2001 - Création de Slim Devices
Slim Devices, Inc. 958, San Leandro Avenue, suite 400, Mountain View, CA 94043, is a Silicon Valley startup with hot products for audiophiles. It's also a next-generation open organization where customers imagine and design the products. Is this the company of the future?
Sean Adams fondateur de Slim Devices.
2006.02.08 "You have to love this sweet, satisfying machine," wrote David Pogue in his New York Times review of the Squeezebox™. The sweet machine in question is a $300 device that lets audiophiles take digital music from their computer hard drives or from Internet-radio streams, and play it with impressive clarity on high-end speakers in their living rooms. "Its creators have sweated so many details, you want to hand them a towel."
This was the prototype for the SliMP3, released in 2001 by Sean Adams:
Early Days.
Ah, but who actually did that sweating? Not just the handful of engineers on the payroll at Slim Devices, the startup that makes the Squeezebox™. The player, which has sold an impressive 50,000 units, is largely the brainchild of its customers around the world, who have done much of the vital engineering and design work--for free.
They've been motivated by their passions for great audio, for cool products, for the art of engineering and also by the satisfaction of being admired and relied on by a global community of their peers.
We know about open-source software and Web services such as Linux, the Mozilla Web browser, and Wikipedia, of course. But Sean Adams, the 27-year-old college dropout who started Slim in his Silicon Valley garage, bet that the same ethos of knowledge sharing and community could extend to a manufactured physical object, one being sold--gasp! for profit.
True, it's a conclusion he came to by accident. Adams had a more conventional company in mind when he was making the rounds for venture capital. He just happened to be looking for funding during the Valley's particularly inauspicious time of late 2001. "Sean wanted Slim Devices to be open source because he didn't have the money to build a company in the usual way," says Patrick Cosson, Slim's vice president of sales and marketing. "It wasn't a political position. It was out of necessity."
And you know what they say about necessity. Slim Devices will bring in around $10 million in revenue this year. Its fans include music stars Herbie Hancock and Alanis Morissette. And its latest product, released last September, the higher-end $2,000 Transporter™, has reaped three times the expected orders.
Slim Devices is still small, of course, and young. But it offers a glimpse of how many companies may come to function in the future: as ecosystems that depend on the active participation of broad networks of contributors. "Everywhere you find innovation today, a community is involved," says Patricia Seybold, author of Outside Innovation: How Your Customers Will Co-Design Your Company's Future (Collins, October 2006).
In this world, running a company is not about brilliance or command, but about attracting and orchestrating the work of talented and passionate outsiders--people who know more than you do, have better ideas, and maybe even care more about your product than you do. As Slim's five-year history shows, there's still an important role for the company and its leaders, but it sure isn't what people have been learning in business school for decades.
People around the world have been contributing to Slim Devices free of charge for all sorts of reasons. Some do it to showcase their skills in the hope of attracting a job offer. Some do it for the challenge. But much of it comes down to this: We want things our way. "Initially, I really got involved because the product didn't do quite what I wanted," says Adrian Smith, who's employed as a network architect for a large telco in Britain. "Instead of just complaining, [Slim] allowed me to roll up my sleeves and try to improve it."
Hard-core audio enthusiasts like Smith, the sort Adams calls "people who will do anything in the pursuit of sound," are the backbone of the Slim Devices community. But what keeps these avid listeners engaged, in fact, is the chance to be heard. Felix Mueller was a software engineer in San Jose, California, a few miles from Slim's headquarters in Mountain View, when he started writing new features for its players.
The startup's bosses treated him with deference when he dropped by its vintage 1950s Silicon Valley building (which originally belonged to Fairchild Semiconductor, the legendary company that invented the computer chip). "When I first met Sean," Mueller recalls, he greeted me with, You must be the famous Felix.
Mueller remained a key member of Slim's community even after he moved to Switzerland. Smith says Slim's executives have earned his trust by relying on his software and "treating me as the expert on how it works."
Slim Devices has depended on its community of enthusiasts to both suggest and create the numerous add-on features that give its products their full richness. But if that's all there was to it, Slim would be merely a customer-centric organization using open-source software development in much the same way giants like IBM do.
Adams's true leap of faith is to let his company rely on nonemployees for much of its most crucial engineering. A particularly vexing challenge for any high-end audio product, for example, is minimizing the amount of power it uses, because electricity creates noise that detracts from the purity of the signal.
And Andrew L. Weekes, the engineer who masterminded Slim Devices' approach to minimizing power, isn't an employee. He works for a company that supplies the British military with target drones, unmanned aircraft that they can use for practice.

Still, he's one of a handful of the community's members who have full access to the product's inner sanctum "firmware," the detailed hardware specs and software that determine how it works. "Vendors told us, 'You guys are insane," Adams recalls. "They said, 'What are you doing? You need to protect intellectual property. You need patents." Instead, Slim's executives decided to put their trust in the contributors who have proven their talent and commitment to the endeavor for several years.
It's a risk, to be sure. But cultivating customer-creators of all stripes gives Slim access to talent that it otherwise wouldn't have. "There are a lot of bored telecom engineers who would move to California if they didn't have families or passport problems," says Cosson. "Half our contributors are abroad--in Canada, the UK, Switzerland, Germany--and this is their way of connecting to Silicon Valley."
Leading a network of outside contributors--if it can be called "leading"--takes some getting used to, says Dean Blackketter, Slim's chief technology officer. He knows this relationship from both sides: Blackketter was Slim's first customer-creator. A seasoned software engineer who had worked at Apple, Microsoft, and WebTV, he bought Adams's first product, the SliMP3 (serial No. 3), out of curiosity.
He saw that the software code that ran the device was posted as open source on the company's Web site. He began making improvements and additions to the code and sending them to Adams, who responded by sending a free SliMP3 to Blackketter in San Francisco (now a common gift to contributors), and then another, and then some stock in the company. In 2002, Blackketter came aboard as the company's second employee.
Now he presides over the community, a task that, among other things, requires a talent for suppressing his own ego. "The hardest part is giving up control," he says. "Do I make decisions myself about changing the product, or do I open it up? Every single time I've opened it up, it's paid off. A couple of times, I've been this close to doing it my way, but they"--the people in the community--"changed my mind. Their hearing is better than mine, their ideas are better than mine. They're doing it because they love it."
At some point, though, the community has to be saved from itself, and that's when Slim's managers step in. One customer wrote a piece of software that enabled Slim's boxes to connect to Rhapsody, Real Networks' online music service. He did so by breaking the code that protected Real's data transmission over the Net. Uh-oh.
The author of the Real plug-in lived just a few blocks from Blackketter in San Francisco. Blackketter went over to his house and said, "That's a really good hack, man," but told him it wasn't legal. Only mildly daunted, the hacker put the plug-in on his own Web site rather than Slim's.
Then, sure enough, an email came from Real Networks asking him to take down the posting--and, in classic Silicon Valley fashion, to visit Real the following week for a job interview. Slim managed to hire him first, then eventually worked out a legal relationship with Real and incorporated the plug-in into its players. "You can't be heavy-handed and kill the creativity," Cosson says. "But you have to manage the chaos and resolve disputes."
As the company has grown, Slim's leaders have learned exactly what the founders of Mozilla Web browser discovered: If you're going to have a grown-up company, with a competitive product in the marketplace, you need a staff of paid full-time employees. They make it possible to meet deadlines and run reliably. Some things have to be handled by staff--such as quality control for the physical product.
And, of course, you can get paid staffers to do what the volunteers pass up or abandon midway. "We think of our development community as this big game room, this big playpen, and we're watching," says Cosson. "If the community can elevate an idea and get it over the hump, that's great. But sometimes we have to rewrite software to finish it." Slim now employs 26 people.
The company's open-source model will increasingly be tested as it grows and matures. Already, Slim's top contributors detect changes in the tenor of the online forums that have been so effective. "The community has grown wildly in the last couple of years," says Kevin Deane-Freeman, who makes his living as a hardware designer for a printer manufacturer near Vancouver, British Columbia.
For several years, he has often spent his lunch break working on software for Slim. "It's no longer possible to keep up with it 100%, nor to make everyone happy. That's a big thing when much of why you do it is to see others happy with what you have provided."
With Slim's full-time staff increasing, there's also a danger that the intellectual center of gravity will shift to the inside. In the past, Blackketter says, "the vast majority of our technical discussions, inside and out," took place on Slim's online forums, "where you wouldn't be able to tell who is an employee and who isn't." Now, Adrian Smith warns, "as the employee team has grown, there are more conversations going on in private."
How Slim manages this phase will determine whether it can be more than just a startup that briefly thrived on the open-source model. "With the open organization, the real question is: Can it scale?" says Ram Charan, the prominent management consultant. Open-source software projects often reach a "forking" point where the community splinters and factions go their different ways.
And while the open-source approach offers a nearly limitless resource potential, "that same potential can introduce an unpredictability," says Deane-Freeman, who signs his postings "not a Slim Devices employee" because of confusion that arose from his frequent and authoritative contributions. "In a larger structure, and especially with a publicly traded company, predictability plays a strong role."
Indeed, Slim's unconventional, open style may prove challenging for Logitech International, which announced in October that it had acquired the company for $20 million. Logitech® promised that Slim would remain autonomous, enthusing over "one of [its] key assets, a committed community of developers." But you still have to wonder whether Logitech® merely covets Slim Devices for its cool audio technology--and whether, ultimately, it will kill off the more valuable invention.

2006-10-18, 15:00 - Annonce de Sean Adams de Slim Devices
I am pleased to announce that Logitech® is acquiring Slim Devices, and I am glad to have the opportunity to share the news here in our forum before the official press release goes out.
We have been building a relationship with Logitech® for quite some time. As we got to know their executive team, it became clear that there was a compelling opportunity for us to work together to bring Slim Devices’ products to the mainstream market. As you may know, Logitech® recently launched the Wireless DJ music system, and also produces Harmony remote controls, which many of our customers already use with their Squeezebox™.
This is an opportunity for us to introduce Squeezebox™ and Transporter™ more quickly to a lot more people. Slim Devices will benefit from Logitech’s brand, their retail channel, their expertise in developing quality hardware, and their existing portfolio of complementary products such as speakers and remotes. Logitech® believes this will be a fast growing segment of their business, and we are looking forward to making that happen.
All of our employees have accepted new employment offers, and we will remain in our Mountain View location. Dean, Patrick and I expect to stay for the foreseeable future.
I’ll be here on the forums if you have any questions, and as always, welcome your feedback and ideas.
Best regards,
Sean Adams (Slim Devices founder)
2006.10.18 - Annonce de Guerino De Luca de Logitech®
Fremont, Calif. Oct. 18, 2006 and Romanel-sur-Morges, Switzerland, Oct. 19, 2006 — Logitech® International (SWX: LOGN) (Nasdaq: LOGI) today announced that it has acquired Slim Devices, Inc., a pioneer in the development of music systems that take advantage of a home network.
Products from Slim Devices, such as the acclaimed Squeezebox™ and the recently announced Transporter™, enable people to enjoy high-quality digital music, in multiple rooms of the home, regardless of whether the music is streaming directly from the Internet, or from a PC, Mac, or storage device on the network.
Logitech® purchased the privately held Slim Devices of Mountain View, Calif. for $20 million in cash plus a possible performance-based payment, tied to reaching certain future revenue targets.
"With the acquisition of Slim Devices, Logitech® is building on our foundation of innovation in digital music and home-entertainment control to address an emerging market," said Guerrino De Luca, Logitech® president and chief executive officer. "Our focus is on people who want to listen to and control their digital music, anywhere in the home. Slim Devices brings expertise in both network-based music delivery and high-quality audio, and a committed community of developers. Slim Devices complements Logitech´s existing technology and human-interface strengths, helping to ensure that we can deliver to music lovers the promise of the digital home."
"With digital music, the convergence between PC technology and home entertainment is particularly evident," said Junien Labrousse, senior vice president of Logitech´s Entertainment and Communications business unit. "Millions of people around the world, in all walks of life, are using their PC or Mac to store their music collection — and those with broadband Internet connections are enjoying the wealth of Internet-radio content and other services. At the same time, increasing numbers of these music enthusiasts have wireless home networks that can be used to distribute the music throughout the home. Logitech® sees significant potential for network-based digital music systems that can enhance the listening experience with high-quality audio, flexibility, choice and control."
In a recent survey of online households in the U.S., conducted by research firm Parks Associates, nearly half of respondents characterized as music aficionados indicated very high interest in the ability to listen to any song, whenever they want, wherever they are, and one third of these respondents were very interested in listening to Internet or computer-based music/audio on their stereo.
According to Parks Associates Chief Executive Officer Tricia Parks, "We forecast music downloads, online radio and music-subscription services at close to $1 billion in 2006 for the U.S. alone. We forecast that amount to increase in the U.S. to over $3 billion annually by 2010. Those figures don´t even count the hardware revenues from necessary adapters and controllers. Clearly, Logitech´s timing for the acquisition of Slim Devices is excellent, just as it was for the acquisition of the Harmony remote business. This fills out Logitech´s wireless music line, and offers audiophiles interested in high-fidelity sound their own network solution."
Slim Devices was founded in 2001 by Sean Adams, serving as chief executive officer, who was joined by Dean Blackketter, serving as chief technology officer. The company has worked with the contribution of a worldwide open source community to develop the SlimServer software, which powers the Squeezebox™ and Transporter™, as well as the SqueezeNetwork, which delivers content to the devices from the Internet, without requiring a PC.
By becoming part of Logitech® , the Slim Devices team gains the advantage of Logitech´s expertise in interface-product design and amplified-audio systems, as well as marketing resources and distribution channels, which include consumer electronics retailers in countries throughout the world.
Led by Sean Adams, the Slim Devices team will become a distinct group within Logitech´s Entertainment and Communications business unit. "Slim Devices has been very successful in developing and enhancing network-based solutions for delivering premium-quality digital music and Internet radio to music lovers, thanks to our effective collaboration with our open source community," said Sean Adams. "Now we have the opportunity to leverage the marketing, sales, distribution, supply chain, manufacturing and engineering resources of a company that shares our passion for innovation in digital music and that can help us reach a wide range of mainstream customers. We´re very excited about joining the Logitech® team to continue to shape the future of digital music in the home."
Labrousse continued, "We´re very enthusiastic about broadening our development efforts with the inclusion of the Slim Devices team and one of their key assets — a committed community of developers."
Logitech® Foundation in Audio and Home-Entertainment Control
Audio is one of Logitech´s fastest-growing businesses, growing by 112 percent in the company´s last full fiscal year, ended March 31, 2006. The growth has been driven by the increasing popularity of digital music, which Logitech® supports with award-winning, premium PC speakers, as well as a line of stylish and high-quality iPod/MP3 speakers and headphones. Logitech® is the worldwide market leader in PC speakers, and is gaining significant momentum in the iPod/MP3 speaker market.
As part of its commitment to the emerging market of wireless music systems, Logitech® recently launched the Wireless DJ™ Music System, which allows people to stream digital music from a PC to a stereo without a home network. The product includes the Wireless DJ remote, which makes it easy to browse and play music selections from anywhere in the home.
Logitech´s presence in the living room includes delivery of digital music as well as control of music and home-entertainment systems. Since acquiring its Harmony remote business in 2004, Logitech® has become the clear market leader in advanced programmable remote controls in the U.S., and the emerging leader in Europe. Distinguished by their ease of setup and use, the Harmony remotes have become widely available in consumer retail outlets throughout North America and Europe.
Impact on Current Fiscal Year
While Logitech® views the long-term potential of the acquisition to be very promising, the impact of the acquisition on Logitech´s current fiscal year is not expected to be material.

Le développement de la gamme avec Logitech®
Pionnier des systèmes de musique sur réseau, Slim Devices avec la Squeezebox™, bénéficie d’un atout de taille à l’heure où le CD cède le pas à la musique sur Internet. Le JDLI a rencontré au cœur de la Silicon Valley, Sean Adams, fondateur de Slim Devices.
D’où vient l’idée de la Squeezebox™?
À l’origine, j’ai travaillé seul sur ce projet car j’avais de nombreux CD mais je ne pouvais pas les écouter où je voulais. À l’époque, Napster était à son apogée et le CD était déjà en perte de vitesse. L’idée était de pouvoir écouter de la musique en profitant des réseaux. Avant le rachat par Logitech® , nous faisions tout nous-mêmes, qu’il s’agisse de l’assemblage ou des expéditions. Quand le marché a été suffisamment mature, nous n’avions pas la capacité de produire de larges volumes avec une bonne finition.
Logitech® commençait déjà à entrer dans le salon avec des haut-parleurs et des télécommandes. Ils avaient un produit appelé Wireless DJ et ils se sont intéressés à ce que nous faisons. 60 % de nos ventes étaient réalisées en Europe, notamment en Angleterre, en Allemagne et en Suisse qui sont des marchés sur lesquels Logitech® dispose d’une énorme expérience et d’un solide réseau de distribution. De plus, Logitech® est passé maître dans l’ergonomie des produits, mais il manquait encore une bonne interface utilisateur et un logiciel puissant. Le rachat a donc été bénéfique à tous les points de vue.
Désormais, nous sommes devenus une division à part entière qui se concentre uniquement sur ce produit.
Quels sont les avantages de la Squeezebox™ par rapport à ses concurrents?
La Squeezebox™ répond à de réelles attentes. En effet, nous avons identifié les différents types d’usage pour y apporter des réponses adaptées. Le gros des utilisateurs cherche avant tout à se débarrasser du support physique et notamment des CD. On veut profiter de toute sa bibliothèque musicale mais sans pour autant rester collé devant son ordinateur. Nombreux sont ceux aussi qui portent une attention toute particulière à la qualité du son.
Le CD a encore une bonne réputation dans ce domaine, malgré les problèmes de disques rayés ou encore des enregistrements de mauvaise qualité. Avec le numérique, il n’y a plus de lecture mécanique et donc plus aucun risque de dégradation, mais il reste le problème de la compression et de la qualité des composants. La Squeezebox™ restitue le son sans en altérer la qualité et elle est capable de lire les formats en Lossless pour offrir la meilleure qualité sonore sans aucune perte liée à la compression.
À quand la fin des supports physiques?
Nous sommes dans une phase d’ajustement. Les gens associent encore la musique à un objet physique. Aujourd’hui, le média devient invisible et il existe de nombreux modèles économiques avec le paiement à l’unité ou par abonnement. Reste le problème des DRM, dont les restrictions ne font rien d’autres que d’ennuyer les consommateurs honnêtes. Heureusement les labels l’ont enfin réalisé et les choses changent. Les radios Internet connaissent également un grand succès et les services de programmation par affinités comme Pandora sont très appréciés pour découvrir des artistes qu’on ne connaît pas forcément.
Au final, les consommateurs deviennent plus téméraires, ils découvrent de nouvelles choses. C’est la même chose pour le MP3. Pourquoi se contenter de quelques chansons dont on risque de se lasser quand on peut disposer de millions de titres accessibles immédiatement par abonnement. En fait, nous abordons actuellement la dernière phase de la dématérialisation. Les gens s’éloignent de leur ordinateur pour l’écoute mais aussi pour stocker car ce n’est ni le plus pratique, ni le meilleur endroit. L’accès direct par Internet est bien plus logique, plus souple et surtout immédiat sans nécessité d’organisation personnelle.
Comment pouvez-vous faire encore évoluer le concept?
Nous allons d’abord nous orienter vers le multi-room, c'est-à-dire permettre aux utilisateurs d’écouter de la musique dans différentes pièces de la maison. Pour se faire, nous allons proposer des produits plus adaptés aux autres lieux que le salon, notamment pour la chambre à coucher, la cuisine ou encore le jardin. Nous nous concentrons également sur le contenu. Avec Squeezebox Network, on peut se passer d’un ordinateur et nous voulons maintenant ajouter de la valeur au concept.
Il y a encore beaucoup de travail à faire en Europe, où les services par abonnement comme Rapsody sont encore rares. Néanmoins, quand de nouveaux acteurs apparaissent, nous sommes d’ores et déjà en mesure de les ajouter rapidement et c’est une caractéristique unique à nos produits. Enfin, nous sommes en mesure d’intégrer notre logiciel dans d’autres produits et nous travaillons étroitement avec les autres divisions de Logitech® dans cette optique.
Peut-on envisager d’intégrer la Squeezebox™ directement dans d’autres produits, comme un amplificateur A/V par exemple?
Certains constructeurs comme Denon proposent déjà des fonctionnalités réseau, mais cela reste basique. Nous discutons beaucoup avec eux, d’autant que notre dernier produit étant pour l’essentiel une télécommande, il est très simple de l’intégrer. Nous pouvons donc le faire assez simplement et pour un coût très contenu.
Peut-on envisager des produits avec des haut-parleurs intégrés par exemple?
C’est effectivement une demande de nos clients et cela semble intéressant. Bien entendu, je ne peux pas tout vous dévoiler, mais vous pouvez avoir une idée en consultant notre forum qui regroupe les demandes de nos utilisateurs. Ils veulent également des écrans plus grands ou encore pouvoir brancher leur équipement sur le téléviseur.
Comment rendre les produits encore plus faciles d’emploi?
C’est un véritable challenge. Même si les consommateurs sont aujourd’hui plus familiers avec les réseaux et les logiciels tels qu’iTunes, ce sont surtout les prescripteurs qui en raffolent. Il n’est pas évident d’expliquer le concept au grand public. Le mieux est de laisser le néophyte essayer et il comprend alors par lui-même. L’idée est de ne pas tomber dans la simplification qui nuirait à l’usage et demanderait l’apprentissage d’une nouvelle logique, comme en leur temps les surcouches à Windows. Il s’agit simplement de proposer une ergonomie adaptée à l’usage et qui suive celle de l’existant en musique numérique et en informatique. Aujourd’hui, une grande majorité des utilisateurs est familière avec ce type de manipulations.
Pourquoi ne pas avoir fait le choix du courant porteur en ligne en lieu et place du Wi-Fi?
Nous suivons l’évolution du CPL de très près, mais cette technologie n’est pas parfaite. En effet, bien que le CPL soit simple à mettre en oeuvre, il ne couvre pas forcément toute la maison, sans même parler des problèmes de coût. Le Wi-Fi est maintenant bien implanté et les utilisateurs savent généralement ajouter un nouveau périphérique sans trop de difficultés.
Qu’en est-il de la vidéo?
Il ne s’agit pas d’un problème de technologie mais plutôt de contenu. En audio, on peut réaliser une copie de ses CD, sans oublier les catalogues en ligne qui sont déjà bien fournis. À l’inverse, il est illégal de copier un DVD et peu de services sont disponibles pour télécharger des films afin d’en profiter comme on veut. Ce n’est donc pas le même modèle économique. De plus, on ne consomme pas de la musique comme des films.
On peut écouter une chanson plusieurs fois sans se lasser ou en fond sonore tandis qu’un long métrage, on le regarde et c’est tout. En se concentrant sur la musique, nous avons réussi à proposer un bon produit, chose que nos concurrents qui font tout n’arrivent pas forcément à faire. De plus, les marges ne sont pas intéressantes et il faut être fournisseur de contenu pour s’y retrouver. Il n’y a pas de marché pour une Squeezebox™ vidéo aujourd’hui, mais nous développons d’ores et déjà des solutions pour être prêts le jour où.
Pour revenir à la musique, l’Europe semble moins bien lotie que les États-Unis, pour quelle raison?
Il existe de nombreux fournisseurs de musique en Europe mais il n’y a pas de système de distribution unifié, ce qui rend la gestion des droits très difficile. Techniquement, rien ne nous empêche de proposer Rapsody et Pandora sur le marché européen mais les compagnies de disque ne nous y autorisent pas.
Pour le moment, il faut donc se contenter des radios Internet. Nous ne sommes pas assez importants pour imposer quoi que ce soit et nous ne pouvons pas faire grand chose pour que les choses s’accélèrent, même si des gens travaillent dans ce sens chez nous. Il semblerait que les rapports entre le législateur, l’économie de la musique et la distribution soient bien plus complexes en Europe avec des intérêts particuliers difficiles à dépasser. Il faut donc du temps.
À quand la haute définition en musique?
Le Transporter™ est déjà adapté à la musique en haute qualité. C’est une demande forte de la part des utilisateurs qui sont lassés de la compression qui engendre une perte de dynamique. Nous sommes en mesure de supporter les formats haute définition, avec notamment le FLAC ou encore le 96 KHz. En ce qui concerne Squeezebox™, ce n’est pas à l’ordre du jour même si elle supporte le FLAC. Dans tous les cas, Squeezebox™ fait aussi bien, voire même mieux qu’un lecteur de CD.
2001 - Le SliMP3
Here is a shot of the front of the unit.
A l'époque où le format MP3 s'est déjà bien imposé, et que des baladeurs MP3 évolués commencent à apparaître, Sean Adams et Dean Blackletter conçoivent, et lancent la production depuis leur garage, d'un appareil qui semble aller à contre-courant des produits offerts par la concurrence: le SliMP3
À la différence de la plupart des autres produits du marché, cette platine est dépourvue de mémoire de masse propre, et récupère directement par streaming (diffusion de contenus) les fichiers MP3 là où ils se trouvent: sur l'ordinateur.
Le but avoué des concepteurs est de permettre aux utilisateurs du SliMP3 de profiter, sur leur installation Hi-Fi, de toute leur collection de fichiers MP3, et pas seulement d'un nombre limité d'entre eux, loin des nuisances sonores associées à l'ordinateur, en pilotant l'appareil grâce à une télécommande.
Le design est minimaliste, et la connectique est réduite à sa plus simple expression:
Views of the back.
Plutôt que d'intégrer dans la platine elle même toute l'intelligence requise pour assurer les fonctions de navigation et de lecture, les concepteurs décident de déléguer un maximum de traitements à un programme serveur de leur conception: le "SliMP3 Server".
Ce programme serveur, écrit en langage Perl, est publié dès l'origine sous licence libre GPL, et les utilisateurs du SliMP3 - essentiellement un public technophile - sont invités à le faire évoluer à leur gré.
Dans la première version du logiciel serveur, seule la navigation par arborescence de fichiers était disponible, le logiciel ne reconnaissait pas les tags ID3 (un choix de Sean Adams, qui considérait que trop peu de fichiers MP3 étaient correctement taggués), et la seule interface utilisateur disponible était celle de la platine elle-même.
The SliMP3 Server Web. The server controls.
The SliMP3 Server Web. The player controls.
Mais, en raison de l'ouverture du code source du logiciel serveur, de très nombreuses fonctionnalités seront ajoutées au logiciel serveur pendant la commercialisation du SliMP3: interface utilisateur Web, support des tags ID3, transcodage d'autres formats audio afin de permettre à la platine de les lire, synchronisation de platines, etc...
Du fait des très fréquentes évolutions du logiciel, celui-ci n'a jamais été livré avec la platine: l'utilisateur était invité à aller télécharger la dernière version.
C'est une caractéristique que l'on retrouvera par la suite avec toute la gamme des platines Squeezebox™.
Durant sa commercialisation, le SliMP3 a connu quelques mises à jour mineures, comme le changement de la teinte du plexiglas ou l'ajout d'un carter de protection:
Caractéristiques techniques:
• Formats audio natifs: MP3 CBR/VBR - 16bit / 44,1kHz.
• Interface réseau: Ethernet 10baseT.
• Convertisseur N/A: Crystal CS4334.
• Mémoire tampon: 1 Mb (8 secondes @ 128 kbps).
• Sorties audio: RCA analogiques.
• Télécommande: infrarouges.
Informations commerciales:
• Date de sortie: août 2001.
• Prix de lancement: 269 USD (249 USD à partir de janvier 2002).
Anecdotes:
• Les 200 premières unités ont été assemblées à la main.
• Pendant les 18 premiers mois de commercialisation, le SliMP3 a été livré
avec diverses télécommandes infrarouge universelles (un guide expliquant
comment les paramétrer pour le SliMP3).

Like almost everybody I know, I've been dutifully ripping my CDs to mp3 files over the last few years. I have a server running FreeBSD that delivers the files through Apache MP3 to any machine on our home network, and now my wife and I can listen to our music on our computers. So why did I balk when my wife suggested putting the physical CDs in deep storage?
Because of our stereo. Thirty gigabytes of MP3 files are fine until you actually want to listen to them in the living room. I tried a homebrew solution a year or two ago, connecting my FreeBSD machine's sound card output to the stereo's input with a very long set of cables, but none of the FreeBSD console MP3 players I could find would successfully play the MP3 files we had ripped with RealJukebox on Windows.
Frustration be gone! In the last year several devices have entered the market that let you play mp3s through your stereo. The latest of these is the SliMP3 from Slim Devices ($250). Small (8.5 x 2.5 x 2) and elegantly black, it has but three connectors: power, Ethernet, and RCA cables to your stereo. To succeed in the consumer audio space, an MP3 appliance has to exhibit this kind of simplicity and elegance in every aspect of its design.
Here's a view of the back.
Physical installation of the unit was trivial. The hardest part was finding an ethernet cable long enough to reach from the nearest hub across the living room to the back of the entertainment center. The SliMP3 FAQ specifically addresses dispensing with the cables and going for wireless; but until it becomes possible to support 802.11b and keep down the cost, the SliMP3 will continue to be cable-bound.
The hardware component of the SliMP3 is only half the picture, though. The SliMP3 speaks its own (open sourced--there's even a SourceForge project for it) protocol with a server to fetch playlists, streams, track information, etc. So you need to run a server somewhere--servers are provided for Linux, Mac OS X, Windows, and (to my exquisite delight) there's even a Perl server. I installed the Perl server in minutes on my FreeBSD box.
Because of the various ways people set up their networks, configuring the SliMP3 wasn't as simple as one button push, but it was close. The option that uses DHCP and automatically discovers SliMP3 servers worked perfectly for me.
The SliMP3 comes with a Sony generic remote, which you must first program (through five or six button presses) to be a SliMP3 remote. This felt out of place in an otherwise seamless install--the TV, tuner, TiVo, and DVD player I have in the entertainment center all came with remotes that worked out of the box. That said, the instructions in the booklet were easy to follow and in no time I was up and running.
The screen of the SliMP3 is one of the first things you notice the crisp 40x2 fluorescent display is very bright and easy to read from a distance. Blind codgers like me will appreciate the option to supersize the text, making it very easy to read from across the living room. When powered off, the SliMP3 displays the time, which turned out to be surprisingly useful in our house. Thanks to NTP, which keeps my server's time accurate, we now have a very visible authoritative source of time around the house.
Here's a view of the front.
What's really cool about the SliMP3, though, is that the server is optionally controllable through its own Web server. From your browser you can change what's playing, pause, change the display, change the volume, and otherwise tweak the SliMP3. That may not sound like much, but if the living room is filled with three year olds who are clamoring for Queen's Greatest Hits, it's sheer pleasure to be able to queue "Another One Bites the Dust" from one's office rather than have to descend into a veritable hell-hole of toddler trouble. Not that this has necessarily happened to me.
Although the default configuration has games disabled, the server can offer games via your SliMP3. Tetris and a horizontal shooter are the two standard games, but other people have extended the Perl server to add their own features. Someone's even written a BBC news ticker. This opens itself up to all kinds of fun: subliminal messages, an interface to FestVox so it can read the headlines as well as display them, a biff-style mail alert, visual load averages for your machines (via ruptime?), fortunes, Choose Your Path adventure games, and much much more.
The Mac OS X SliMP3 server installed trivially, read my iTunes databases, and even noticed when I updated my iTunes database. Because the SliMP3 server can translate streaming MP3 formats like Shoutcast, Icecast, and Live365, I was able to drag the KCRW public radio simulcast to my Library and within a few seconds it was available on the SliMP3 player. I don't think anything has impressed me with the SliMP3 as much as this. Now if only my local NPR station offered an MP3 stream instead of RealAudio and Windows Media!
From the SliMP3's remote control you can browse and search saved playlists, albums, artists, and genres. This quickly taught me how appallingly tagged my 30 gigabytes of MP3s are--I like basic genre distinctions like "Jazz", "Rock", "Bluegrass", "Classical", and somehow I have MP3s that are tagged with genres like "Alt-Folk", "General Folk", "Folk-Rock", "Contemporary Folk", and many other variations on the same theme.
There's also some dubious classification--while The Proclaimers' "I Would Walk 500 Miles" is arguably Blues, Lenny Henry's "Live and Unleashed" album is far from "General Classical". Fortunately, the SliMP3 lets me browse the music folders as they're laid out on disk. Because I have a sensible directory structure, if not consistent tagging, I can quickly find what I'm looking for.
Tracks start playing as soon as you hit the play button on the remote control, and I've not once noticed a network lag. In fact, the SliMP3 is blazingly fast and puts the TiVo and on-screen cable guide to shame. It's possible to find the album or track you're looking for very quickly, once you have your head around the SliMP3 menu system.
The SliMP3 has features I haven't used in the week and a half that I've had it. For example, there's an alarm function that will make it play a specific track at a particular time. I haven't found a killer app for this (three year olds act as organic alarm clocks, although there are times when I wish their volume and playlist was as variable as the SliMP3's) but I'll keep trying.
The SliMP3 isn't perfect, though. The power button on the remote control repeats, so it's easy to turn your SliMP3 on only to turn it off again immediately. It's also easy to get lost in the maze of browse and search options, and it takes a lot of time to get used to when the remote's left arrow backs you out of a menu vs when it returns you back to the root menu (this is, however, configurable via the Web server). These are minor UI glitches, though, and the overall convenience and functionality still leave the SliMP3 ahead.
Overall rating: 9/10. The SliMP3 is a perfect gift for the MP3-collecting geek in your life. Santa gives it two elves up!
RF Interference
I am no expert in RF shielding, but I believe the lack of a grounded metal enclosure hurts the SliMP3. The exposed circuit boards and minimalist design has an extremely high geek factor, but it's possible to be too minimalist.
During the evening I received my SliMP3, the server seemed to be having trouble keeping up with the demands of the client. I would get drop-outs after songs had been playing for a few minutes. The next morning the problem was gone. The whole next day the SliMP3 worked flawlessly. The next night it started having problems again. I turned on debugging in the server and on the client via some flags documented in the code.
The client was requesting retransmits for lots of packets. After spending several hours replacing cables and trying to narrow the problem down I gave up and turned the lights out preparing to go to bed. When I went back to the server I saw that the retransmit requests had stopped. It turns out the dimmer in my floor-standing lamp across the room produces enough RF to interfere with the data getting to the CPU of the SliMP3.
I tend to think that the interference is occurring on the board, since I've never had any trouble with twisted-pair near this same lamp, which I've had for years. I've heard of lamps like this interfering with DSL, but never Ethernet. In any case, since I've stopped using this lamp the SliMP3 has been fine.
I have also seen significant diagonal interference patterns on broadcast TV channels 3 and 4 when the SliMP3 is powered. (I suspect that cable TV would be unaffected by this). I don't watch much TV, but it's another sign that proper shielding is warranted.
Conclusions
Despite some blemishes, the SliMP3 is a good product and I have no doubt it will continue to improve with further development. It is already an impressively functional device, nicely filling a niche for open network-based MP3 players. If you have the hacker mentality, a bunch of MP3s, a UNIX box and $249, you would be hard-pressed to find a more suitable player. The ability to easily modify the fundamental behavior of a consumer electronic device is just too cool.
And it makes nice sounds too
It is clear that the people who designed the SliMP3 have a clue. They designed a product they wanted to use themselves, and those are invariably the best products. Before you buy, check out their website, read the FAQ, look at their pictures, read the development mailing list archives. To the right kind of person, the SliMP3 sells itself.

Album covers for your SliMP3 - What's this all about?
It's easily one of the coolest electronic gadgets I have ever bought. One of the nice things about it is that it includes a Web interface to control the player, including all the playlists and such. This feature also has the ability to show the album cover in the Web interface, if an image file is in the same directory as the mp3s. Looks something like this (note that this image is scaled down to 800x600 to be of reasonable size).
The problem I ran into was that I had a huge number of CDs and wasn't about to spend an insane amount of time scanning in every album cover. By an odd coincidence, at this same time, I discovered Amazon's SOAP interface to their database. A solution quickly evolved to meet my problem. It's possible to query Amazon's database for a given title, and pull down the image for the album cover from their site.
This script will run over your mp3 directory, look at the ID3 tags of the mp3s it finds, and will perform several different types of searches on the Amazon database to find the closest matching album. It will then download the album cover, if it's available, and place it in the corresponding directory for that album.

Reg Review I have a dream, ladies and gentlemen, of listening to music of my choosing that has been pumped through the ether as if from nowhere. There are no discs to change, no turntables, drives or tape mechanisms to disturb the concentration, just pure audio, accessible on whim and a player.
Compact Disc welcomed us to the world of digital music. Almost two decades later, MP3 realised the potential of compressing music to make possible archiving huge quantities of the stuff. Today's monstrously capacious hard drives allow us to build that archive.
One thing spoils this audio heaven: the need to wire said hard drive to the hi-fi. There have been hi-fi units equipped with hard drives, but nothing beats a personal computer for ripping and managing an audio collection. But most computers, even Apple's don't sit well alongside a living room entertainment system. And who wants to walk over to a PC to set a player app in motion?
What's needed is a way of keeping your music in one place - the computer up in the spare room - but which lets you listen to it from the comfort of a fine leather reading chair in the lounge.
Enter Slim Devices' Squeezebox™, a remote music access point that uses the magic of Wi-Fi to enliven your hi-fi, without forcing you to physically merge the worlds of consumer electronics and computing.
The Squeezebox™ is about the size of a large, 'trade' paperback. At the back sit a set of digital and analog outputs, a 10/100Mbps Ethernet port, a screw-on WLAN antenna and the power jack. There's a 3.5mm headphone jack on the side. Up front, you'll see a large, crisp two-line LED panel, slightly larger than the kind you might see on a DVD or CD player. There are no controls - the Squeezebox™ is operated by remote.
Get connected
Connecting the Squeezebox™ to an amplifier is straightforward. And in a real challenge to claims that Wi-Fi isn't easy to use, getting the unit to talk to your WLAN is equally clear-cut.
Go wired or wireless, analog or digital, open air or headphones.
It really is a doddle. Plug in the power cable, wait the briefest of moments and the Squeezebox™ takes you through a short series of steps. First, select your WLAN's SSID. If there are several in the vicinity, you use the up- and down-arrow keys on the remote control to find the right one. Press the right-arrow key when you've done so.
Next, tell the device whether the network is secure or not. If it is, you enter the 64-bit or 128-bit WEP encryption key using the remote's numeric pad. I tried the Squeezebox™ on an open, public network and on my own, rather more tightly tied down home WLAN, and had no trouble getting it to work with either. Having fought with Wi-Fi and WEP before, it was nice to have something wireless work first time.
Moving on, you're subsequently asked whether the device's IP address will be assigned or is static. I choose the former, and the Squeezebox™ promptly requested one from the router.
Finally, you're asked to select the computer on which Slim Devices' open source server code is running. Again, there may be more than one, so use the arrow keys to locate and select the one you want. And that's it.
The light-weight server software (written in Perl, incidentally) has to be pre-installed on the computer holding your music archive, of course, but that's not likely to tax anyone smart enough to rip their CDs. Slim Devices not only supports the various incarnations of Windows, but Linux and Mac OS X, which wins it much praise from this quarter and a big yah-boo-sucks to its Windows-only rivals. You may need to tweak your firewall, of course.
With the system in place, you can start playing your songs. The Squeezebox™ features a straightforward search system, allowing you to locate tracks by artist, album title, song name and so on. And you can browse the entire contents of your music folder.
The remote's numeric pad uses the same alphabet clusters as a mobile phone keypad, so entering a few characters or even a long album title is easy. The Squeezebox™ uses that to interrogate your music collection, and displays a lists of items which fit the bill. Again, you just step through the list using the remote's arrow keys.
There are slight pauses as the box talks to the computer via the WLAN, depending on the level of background traffic, but controlling the Squeezebox™ itself is quick and responsive. Select an album, press Play, and the device will start running through song by song.
It maintains a dynamic playlist to which you can add songs by finding them and hitting the Add key. This quickly lets you build up a dinner party playlist, greatest hits selection or whatever. Removing them is trickier, but possible.
The remote also provides the usual pause and track-skip keys, along with shuffle and repeat play order controls, and a handy Now Playing button. You can also set the LED display's brightness and switch it to show a magnified, single-line read-out. You can also control the Squeezebox's output level with a pair of Volume buttons.
Multi-format playback
The Squeezebox™ plays back MP3 files by preference, but it can cope with iTunes' AAC files (providing they're DRM-free) and Ogg Vorbis tracks, but you'll need extra software to do it. Slim Devices could have done a better job at explaining how this is achieved, and even bundled the appropriate code. But a quick download of Blacktree, Inc.'s iTunes-LAME Encoder - linked from Slim Devices' FAQ - solves the problem.
It includes a version of LAME tailored to transcode AAC and QuickTime's .MOV formats to MP3, which the server software streams across to the Squeezebox™. There are Windows equivalents for PC-based iTunes users. LAME and Oggtools are enough to do much the same for Ogg Vorbis archives, says Slim Devices.
AAC transcoding is set up to convert to uncompressed AIFF, but transmitting all that data proved too much of a limiting factor on my 802.11b network. AAC-encoded tracks songs sounded choppy, with small sections of each track missing.
The squeezebox™ keeps time and ignores dropped packets, simply picking up the audio when it returns. So if you lose half a four-minute, say, it won't take more than four minutes before the next song starts.
That said, you do occasionally see the counter get out of sync with the song, a phenomenon that manifests itself as the next track appearing on the display before the previous one has finished.
Shutting down the missus' Citrix client, helped, but configuring the server software to convert to AAC to MP3 rather than AIFF led to a big improvement. Again, this tip comes from Slim Devices' FAQ and a separate download but should have been part of the package.
I didn't experience any of these problems with native MP3s (apart from the track counter synchronisation) and Slim Devices claims its machine works equally well with uncompressed WAV and AIFF files, for those who prefer the true CD quality audio - just make sure you've got plenty of bandwidth.
Inside the Squeezebox.
The sound quality was good, with the caveat that what you get depends on what level of compresssion you use on your archived songs. While an oscilloscope might reveal the addition of noise to the audio signal, my ears couldn't. Like me, you may have to make some adjustment's to the Squeezebox's own Volume, Bass and Treble controls to allow you to set your amplifier's volume to the level you're used to having it at.
With my Music folder copiously filled with classical, rock and spoken word repertoire, and an extensive if eclectic playlist ticking away on the Squeezebox™, I settled down with a large glass of Wirra Wirra Church Block to enjoy this realisation of a dream I've had for nigh on 20 years: tens of thousands of songs, all no more than a few remote control button presses away.
Slim Devices' gadget isn't the only one of its kind, and not the first, but it deserves praise for its cross-platform and multi-format support. And it doesn't pretend to be anything but a music system. So there's no attempt to let you view holiday snaps on your TV, or even the suggestion that your 802.11b network will happily cope with full-screen, full-motion video.
The squeezebox™ was a joy to use, particularity once the AAC problem had been resolved - a problem that wouldn't have existed had I had the bulk of my music collection in MP3 format. With MP3s, there really was no problem, and I could sit back and enjoy my playlist, or leave it running in the background while I offered my guests drinks.
The one downside - and it's a minor one - is the WLAN support. With a newly installed 802.11g network, it's a shame to have to drop down to 802.11b for the Squeezebox™. Roll on the higher specked version, I say. And hopefully a more comprehensive set of instructions and bundled software while Squeezebox™ is at it. Having to download code makes for a more up-to-date install, but it's not entirely consumer-friendly
Upgrade Squeezebox™ 1/1G
Case for Squeezebox™ 1/1G
The case is refurbished from an earlier project. It's really only a folded sheet of metal, without a left, right and bottom part. The front is a piece of plexiglass with a black layer in between. I had to add something to the front to cover the holes from the earlier project.
The long and thin display cable added additional resistance to the powerlines causing the diplay to show 'garbled' output and also fainting. To compensate for that I added a big capacitor (about 2200uF) to the powerlines.
Sidenote: It's not that I don't like the original case, but my prototype Squeezebox didn't have a case so far.

2003 - La Squeezebox™ 2 (v2)
The Squeezebox™ 2 is a high-tech piece of computer hardware that plays computer music files and internet radio stations through its built-in Toslink or coax digital outputs (or its analog output), but there is more—the Squeezebox™ 2 can stream musical ones and zeros from a remote location via its built-in 802.11g wireless capability, or hardwired via an onboard Ethernet connection.
Modèle avec Wi-Fi.
Modèle sans Wi-Fi.
Slim Devices also makes an Ethernet-only version for the wireless-challenged, but for an additional fifty smackers you get both. This seems like a no-brainer to me. Small in size, the Squeezebox™ 2 could easily be confused with a Sharper Image clock radio if weren't for its elegant fluorescent display ticker-taping the names of rock anthems and Bach sonatas across its front. Just so you know, it also has a setting that allows it to be used as an alarm clock!
The Squeezebox™ 2 must be controlled from a computer running special software. This software, called Slim Server, is open source, which means that it is freely distributed, and that anyone who has the desire and knowledge can tweak, add to, and/or create updates and new applications.
When installed on a Windows, Mac, or Linux-compatible computer, the Slim Server software runs as a Web-based interface that allows the user to control all of the SB2's functions, from setup to music file management to internet radio capability. You can close the Web browser window without stopping the server, in which case it will run "silently" in the background, playing music files stored on the computer.
The software can also interface with Apple's iTunes, incorporating all of its existing music files and play-lists. The thing has so many options and parameters that an entire book could be written about it, but instead of continuing to butcher the digital-operative lingo, I will describe my experience with this third-generation Slim Devices music player.
I have no experience with Slim Devices' inaugural product, the SLIMP3 Networked Music Player, but I do own the first-generation Squeezebox™. Because I was satisfied with its performance as a whole-house music server, I gave it a trial run in my main two-channel system.
While not awed by its performance, I was sufficiently intrigued that when the Squeezebox™ 2 with its faster, wireless connection and supposedly more robust audio performance—was announced, I immediately put my name on the list for a review unit.
My previous experience had prepared me for wading through the treacherous waters of wireless computing. Using the 802.11g wireless standard, the Squeezebox™ 2 is much faster than the original. Gone are the occasional dropouts and slow access times that compromised the functionality of the first Squeezebox™.
The Squeezebox™ 2 is a terrific upgrade for the same money. It is faster, has nearly zero dropouts, and with its new Burr-Brown DAC and low-jitter clock, the sound approaches a level that even the most jaded audiophiles can enjoy.
The big difference between the Squeezebox™ 2 and every other audio component in my home is its relative complexity. Does that mean that it is difficult to use? Yes and no. Though it certainly helps to be computer-literate, anyone who has downloaded and installed software from the Internet will find the Squeezebox™ 2 easy to set up.
The earliest versions of the software had a penchant for crashing emails and documents as you tried to save them, but this has been fixed, and I have had very few problems.
In addition to all of the computer crazies that have pushed the evolution of Slim Server along so rapidly, there are many folks developing software add-ons and plug-in programs to use with the SB2. The fact that the Squeezebox™ 2 should continually improve for some time to come is one of its most important virtues.
At a time when technical obsolescence can occur virtually overnight, it is comforting to know that someone will always be trying to make the SB2 work better, even after it is no longer the new toy in town.
Now that you have downloaded the Slim Server freeware and have it running, you are ready to rock, right? Perhaps so, if you are using an Ethernet connection or already have a wireless system in place. If neither is the case, I'm afraid you'll need to set up either a wired or a wireless network.
Both are simple tasks—for a computer geek. I went wireless, as I wanted to be able to move my system to different rooms without having to run a CAT5 cable to every corner of my little house on the prairie.
I have a wireless Access Point that is connected via Ethernet to my hardwired router. I was lucky enough to have a spare CAT5 cable from my router to a centrally located closet that was no longer being used for computer duties.
This location gives me great coverage, and I get a wireless signal strength that averages in the 80 percent range. Setting up the Access Point was not entirely painless–it took a week or two to get the gremlins out—but once accomplished, it worked without a hitch.
Though the Squeezebox™ 2 itself must also be set up, this is MUCH simpler than it was with the original Squeezebox™. (I don't really know why, but without a doubt it is. I only know enough to be dangerous—I read the directions and when I can't make it work, I get my kid to fix it.)
The good news is that the new unit will usually connect automatically, but it might not, in which case a bit of sleuthing is in order. It certainly helps to have a modicum of knowledge about IP addresses and DNS servers. You don't have to be Bill Gates, but a computer novice will undoubtedly struggle if things don't go smoothly.
It might be smart to have the computer cavalry on standby, they may need to ride in and save the day. It should also be noted that funny things happen when the power goes off, so after a storm knocks out the grid, your Squeezebox™ may have some (hopefully) momentary brain dysfunction.
Every system will be different, so there is no magic bullet except rolled sleeves and good fortune. If I've made setting up the SB2 sound like a task of Herculean proportions, don't fret, because truthfully, almost anyone can do it.
Once the system is up and running, it will need some tunes to play. You could load crappy MP3 files onto your computer's hard drive, but hey, we're power users here in audiophile land! I purchased a Maxtor 300-gig external USB hard drive, then spent days and days ripping (transferring via a computer program) all my CDs with Apple's iTunes program, converting from Redbook format into Apple Lossless files to save space while leaving quality intact.
I currently have almost 6000 songs by over 440 artists, with room for another 5 or 6000 before I have to run out and buy another drive. And yes, any prudent person would have a second drive set as a backup in case a crash takes place. It did take an excruciatingly long time to rip all those CDs, and I would hate to have to do it again. I guess I'd better become a prudent man. and soon!
While the Slim Server is quite adept at running the SB2, it is a bit rough around the edges. Since you need a separate program to transfer your digital discs to the computer anyway, and being a simple kind of guy, I settled on iTunes to handle my music management duties.
Many computer music gurus swear by Exact Audio Copy (EAC) to convert CDs. If they want to save computer space, they convert those WAV files to the lossless compression format of FLAC.
While this may yield superior file transfers, to the best of my knowledge, FLAC files will not work with iTunes. Why, then, do I use it? Apple's Lossless format sounds very good, and that makes it simple. This is my version of simplicity:
1. Download iTunes.
2. Set iTunes to convert CDs to Apple Lossless format with error checking
enabled.
3. Rip hundreds and hundreds of discs.
4. Make up play-lists to your heart's desire.
5. Enter the path to the iTunes folder in the Slim Server software.
6. Play back play-lists by choosing them either in the Slim Server software at
the computer, or by using the remote control to scroll through them in
the Squeezebox™ 2 display.
That is the abridged version of setting up the Squeezebox™ 2. If you want more information, you'll need to visit the Slim Devices' Website, where you can download the software, check out the FAQs, and browse the informative user's forum. It will also be worthwhile to find a good computer Webzine review, which will surely touch upon many more set up issues and options.
The SB2 clearly outperforms the original Squeezebox™ by a wide margin and in every category, including sound. Both units offer a remote control that operates every necessary function. Its operation is intuitive.
After scrolling through the functions a few times, even the most tech-adverse should be able to access music, change volume, play internet radio, and execute the basic commands: play, pause, next track, and stop. There is a dizzying array of options, mostly having to do with set up of the unit.
The only ones I really use are displaying the setup menu, setting the fade in/fade out/crossfade options, and choosing where to locate my default music storage folder. When setting the display, there are many different visualizers to choose from, including analog VU meters and scrolling newscasts, but I chose to see the title, artist, album, and year of the music being played.
Again, I have only scratched the surface of what is available. Anything beyond the best sound with the fewest glitches is computer gee-whiz territory and not my bag.
One very cool thing about the little black plastic Squeezebox™ 2 is its ability to stream SHOUTcast, Radioio, and Live365 Internet radio stations. If you've never used Internet radio, it is a great way to listen to music and stimulating discussions from around the globe. One night I lucked onto an Irish radio station playing drunken jigs and reels streamed live from a Dublin pub.
Internet radio makes the Squeezebox™ 2 worth the price all by itself, but what could be even better is a feature so new that I have yet to really use it—the SqueezeNetwork, which has just been introduced, promises to allow the SB2 to connect to services like streaming radio without running the Slim Server (hence the computer). Righteous, dude!
If small and simple is your ideal, buy a Squeezebox™ 2, connect it directly to a power amp or powered speakers, and control the volume via the Squeezebox™ 2's 40-step digital volume attenuator. You'll have a fine, simple audio system. To hear the SB2 at its best, selecting two options in the Slim Server "Player Settings" window is very important.
Disabling the digital volume control by selecting "Digital output level is fixed" and "No Limit" on the bitrate option allows the Squeezebox™ 2 to bypass the digital volume control and play files at their highest recorded bit rate, with the following caveat—at present, file playback is limited to 48 or 44.1khz sample rates or below in the PCM audio format of 16 or 24 bits per sample.
As a computer-based digital playback system, one of the most important features of the Squeezebox™ 2 is its ability to play a plethora of popular computer music formats, including .WAV, Apple Lossless, Windows Media, FLAC, Ogg Vorbis, and of course, the dreaded MP3.
Aside from great sound, the ability to play lossless formats is (to me) the SB2's most important feature. Without this capability, my hard drive space would be nearing extinction, yet I would never commit the sacrilege of converting perfectly good CDs to MP3 for playback through a Fi-X tube amp!
As I have gained experience as an audio writer, it has become increasingly difficult for me to describe the sound of components. I have become keenly aware that great audio reproduction can only be the result of a carefully assembled system. This is especially true of the Squeezebox™ 2. Its built-in Burr-Brown DAC is lightyears beyond its forerunner in sound quality.
While the SB2's internal DAC really does sound very good—stout bass, extended treble, clean mids, and excellent resolution—it seems a bit sloppy and ragged compared to its S/PIDF coax output connected to my Birdland Odeon-AG DAC. In my opinion, it is the SB2s new lower-jitter digital output that allows it to become an integral part of a high-performance audio system.
While I am not going to give you the usual blow-by-blow audiophile commentary, there are some important things to note about the Squeezebox™ 2's performance with an outboard DAC. Using its coax digital output, the SB2 is very silent. A lot of audiophiles dislike the word "neutral," since no one can really define what it means.
Still, the Squeezebox™, used as a transport, does not seem to add any sound of it own. How do I know that? For a short but sweet time, I had an Audio Note DAC connected to the SB2. The AN's sound was amazingly forthright and highly transparent, with deep bass, extended treble, and wonderfully rhythmic drive. Alas, the unit eventually traveled eight hours north with its owner.
The Odeon-AG sounds wholly different than the AN. Its resolution at low levels is stellar, as is its imaging. It also has beautiful tone, and the sound just pours out in a pure, musical stream. Nevertheless, it has less drive than the AN and lacks the AN's deep bass capability.
Both DACs sound wonderful, and both sound distinctly different. With both, I can hear the Fi-Xi doing its brilliant 2A3 tube thang, and can clearly hear the differences in speakers, so without further ado, I pronounce the Squeezebox™ 2's digital output to be neutral.
Does this mean that I think the Squeezebox™ 2 is the best digital transport around? Hell no! But I do feel that it compares nicely with many of the disc slingers I've tried. Paired with the Birdland DAC, it is not in the same league as the Lector Alphatop, which is the finest I have heard. The combo sounds different than the high-energy preciseness of the Cary 303-200, but very much like the laid back Metronome.
It should be noted that I no longer strive for the ultimate stars of audio space. My gear is good, but simple and relatively inexpensive. My focus is on synergy and great sound for the money.
The Squeezebox™ 2 lacks the effortless air and space of the best digital gear I've heard, so it might not be the best transport for a megabuck, pick-out-the-rosin-on-the-bow system, but you know what? It kicks ass in the realm of convenience, and sounds really, really good doing so.
The SB2 is making some waves in the DIY and high-performance modding community, and there are some talented people who are engineering modifications to take this unit to the next level of performance. One modder in particular, Vinnie Rossi of Red Wine Audio, has taken the SB2 off the power grid.
Vinnie tells me that his extensive internal modifications and SLA battery power improve the SB2's sound to the point that an outboard DAC is no longer needed, and he uses the digital volume control!
Something new and perhaps better is always right around the techno-corner, but by waiting for the perfect solution we sometimes miss an opportunity to try a truly innovative product, even if it is not perfect. There are other devices on the market that wirelessly stream music, and they may be just as terrific as the SB2.
I bought my original Squeezebox™ for its Apple Lossless capabilities, and I will be buying the Squeezebox™ 2 for its excellent audio performance. I now use the SB2 daily for critical listening, and I am blissfully in the land of fingertip music. It is an addictive and marvelous way to listen.
It is like having my own high-quality radio station, without the brainless, time-wasting commercials. I cannot say that the Squeezebox™ 2 is for Joe Everyconsumer, as it has all the quirky earmarks of computer-based technology, yet the SB2 is so astoundingly convenient, and sounds so good, that it can no longer be ignored.
If you can deal with the vagaries of computers, are willing to commit a few bucks to set up a wireless network (or even just a Ethernet cable slung through the house), and don't mind spending a few days, or weeks, converting CDs into computer files, you can have a wonderful taste of audio's future right now, for a mere 250 dollars.

Logitech® transporte la musique de votre serveur personnel vers ce "lecteur MP3 de salon"... Une solution intégrée accessible depuis une télécommande!
Plus exactement, la Squeezebox™ 3 est une sorte de lecteur MP3 et Radio Internet "tout en un" qui peut facilement s'intégrer au milieu de votre installation "Domotique". Dans son cas, on parlera plus volontiers de "Convergence Numérique".
Cet appareil se substitue avantageusement à des solutions dites "intégrées de salon". Il sait tout faire en terme de diffusion sonore numérique.
C’est un relais entre votre PC et votre amplificateur qui permet de jouer, (Sans fil ou câblé), tout ce qui en provient: MP3, Webradio …Un peu le "grand frère" de l'ExSteamer en version beaucoup plus jolie et télécommandable, une version "Wi-Fi" du module CPL Dlan-Audio, et surtout la concurrente directe du Philips SLA5520.
La Squeezebox™ 3 est un lecteur "audio-stéréo" qui utilise la puissance d'un réseau informatique câblé ou Wi-Fi dans votre maison pour distribuer un signal audio. La Squeezebox™ 3 peut lire tous fichiers audio venant d'une radio Internet ou du disque dur d'un PC branché sur votre réseau.
La Squeezebox™ 3 diffuse la musique depuis votre ordinateur vers votre chaîne Hi-Fi, au travers de votre réseau sans fil Wi-Fi ou Ethernet - sans aucune perte de qualité sonore. Vous avez alors un accès instantané à n'importe quel morceau de musique numérique, depuis n'importe quelle pièce.
Les connecteurs numérique optique, coaxial et analogiques permettent toutes les connexions hi-fi, "home theater" ou enceintes amplifiées. La Squeezebox™ 3 Wireless peut servir de pont Wi-Fi pour connecter un autre appareil compatible réseau via le port Ethernet.
De la taille d’un petit routeur, une vingtaine de centimètres en longueur et une dizaine en hauteur, la Squeezebox™ 3 est un "lecteur MP3 de salon" original qui fonctionne avec n’importe quel ordinateur, PC ou Mac.
La Squeezebox™ utilise le fameux Burr-Brown Advanced Multi-Bit 192kHz 24-Bit DAC AK4396 bien connu des audiophiles pour produire un son pur et une distortion minimum:
► For more information: click here
La connectique numérique-optique, coaxial et analogique permet de relier l'appareil à tout système tel qu'un home-cinema, des enceintes stéréos ou amplifiées.
Tranquillement installé dans votre salon, télécommande en main, vous parcourez votre collection de MP3 et arrêtez votre choix sur un de vos titres préférés. L’écran très lumineux de la Squeezebox™ 3 de SlimDevices affiche l’essentiel : artiste, album, chanson. Une pression sur un bouton et le tour est joué, la musique sort des enceintes.
Un logiciel installé sur cet ordinateur se charge de la gestion de vos MP3 et le tout est relié au lecteur en W-iFi, permettant de laisser le disgracieux et bruyant PC dans le bureau ou dans un placard. Un des inconvénient de ce produit est qu’il faut un PC allumé en permanence quelque part pour stocker les MP3.
Le fabricant travaille sur la possibilité d'allumer et d'éteindre le PC directement depuis la télécommande. (Une mise à jour qui se ferait par un simple changement de logiciel). La compatibilité infrarouge de la télécommande laisse prévoir une reprise à partir d'une télécommande universelle type "Pronto" de Philips™" ou même d'une SRU9600.
Fort d'un très bon écran VFD, (Vacuum Fluorescent Display), naturellement lumineux, donc visible jusqu'à quatre ou cinq mètres, la Squeezebox™ 3 se fond naturellement dans un ensemble Hi-Fi ou "home cinéma". Reliée à l'amplificateur par un câble RCA, comme celui utilisé pour les lecteurs CD ou par une connexion numérique via une prise coaxiale, elle délivre un son remarquable.

While you may never have heard of Slim Devices, this small start-up originated the networked audio player market back in 2001. The concept behind the company was to produce a slim device, minimalistic on the player client side and powered mostly by the server. The theory behind this is that adding functionality and features to the player client is complex and expensive. CPU and firmware resources are at a premium. However, providing the computing horsepower and features on the server side is much easier and cheaper. It also makes implementing radical changes trivial by comparison.
The Slim Devices Squeezebox™ 3, now referred to again as the Squeezebox™, is the company's 4th generation product. The company's first product was the SLIMP3, a 10 Mbps Ethernet-only, MP3-playback-only device. The first Squeezebox™ added 802.11b wireless capability with WEP security, a larger buffer, a larger screen and many more playback formats.
A Squeezebox™ update was the addition of a graphical display, which could be installed by the user in earlier Squeezebox™. The Squeezebox™ 2 updated the Squeezebox™ hardware with 802.11g wireless networking, WPA security, a very large buffer, an even larger display, improved audio circuitry and support for more audio formats.
The latest Squeezebox™ product, which just started shipping November 1st, shares its hardware with the Squeezebox™ 2 but uses an entirely new housing, a filter to change the screen colour to aqua and a new power supply that emits less radio interference. Support for native WMA decoding was introduced, which also updated the Squeezebox™ 2. The company's thinking is that the external looks finally match the unit's internal sophistication.
The Hardware
The Squeezebox's housing is a brand new look for the company. It is composed of brushed aluminum, an aqua-coloured display and gloss black finish around the sides and back; white is also available. It looks extremely stylish - almost Mac-like. It's sitting on top of my Energy C-5 right speaker, which seems to have been made for it!
This is a radical design change for the company, which housed the first Squeezebox and the Squezebox2 in an angular, boxy housing with a prominent external antenna:
Squeezebox 2.
The most eye-catching part of the Squeezebox design is the gorgeous 320 X 32 X 2-line graphical vacuum fluorescent display that's really a sight to behold. These sorts of graphical displays are usually only used in commercial and industrial devices as they are simply too expensive for consumer-level devices. Consumer manufacturers have moved on to LCD displays instead. But Slim devices, in a decision which gives you an idea about the philosophy of this company, found backlit LCDs too dim to be read from across a room and decided not to sacrifice quality to save cost.
The Hardware con't.
From left to right is the headphone connection, the right and left analog outputs, the optical digital output which I'm using, the coaxial digital output, the Ethernet port and the power jack for the tiny "wall wart" power supply, not much bigger than an ice cube. Note that BOTH optical digital and coaxial digital outputs are included. Slim Devices offers the Squeezebox in wireless and lower-cost wired versions. In the wireless version, the unit can operate in either wired or wireless modes. If it's operating in wireless mode, plugging a PC into the Ethernet port can turn the device into a wireless bridge. The unit will operate as a wireless bridge and as a normal Squeezebox simultaneously. How cool is that?
There really isn't as much dust on top of the unit as it appears! The housing is so glossy that the overhead room lighting made it very apparent. This photo was even taken after cleaning with the included microfibre cloth.
A small and fairly mundane 3rd party remote is included, which is white for the white units:
Internally, the unit contains an 802.11g wireless receiver with a large 40 Mbit (5 MB) audio buffer to avoid dropouts in adverse wireless networking conditions. This ensures playback for several minutes after the unit has lost a signal. To avoid marring the unit's looks yet have good wireless reception, there are two internal antennas.
Wireless security is through WPA or WEP, although no encryption is supported as well. WPA2+AES is coming soon. The unit can support non-broadcast SSIDs and it can use a DHCP-assigned IP address or a static IP address.
Slim Devices lavished a lot of attention on the audio circuitry to ensure high-quality playback. Two separate linear power supplies are used for the DAC (digital-to-analogue converter) and line-out stages. The device uses a 24-bit Burr-Brown DAC for its analogue output. This is better than most CD players and at least as good or better than the DACs found in most audio/video receivers. The digital audio circuits also get special treatment. Rather than use cheaper PLL-based timers, it uses dual high-precision crystal oscillators
Unlike soundcards and A/V receivers, there is no conventional digital signal processor, or DSP, used to process the sound. Instead the code sits in the unit's flash memory and portions of it are retrieved as needed. The unit's 250 MHz RISC CPU then does all the decoding work rather than a dedicated DSP chip which would not be nearly as powerful. This also means new decoding formats and performance enhancements can be added very easily. For example, the latest firmware update added native hardware WMA decoding capability.
What do all these audio terms mean, you ask? It means that Slim Devices has spared no expense to bring you the highest quality audio possible. You will have to pay careful attention to your source material as the Squeezebox can easily reveal any compromises you have made in CD ripping. It is far more accurate than a consumer-level CD player.
Oh and to tempt us, the headphone output is not merely a headphone output, it is a multi-functional "geek connector" that can enable advanced control. Currently it only supports an IR blaster that can remotely control other devices besides the Squeezebox, but other applications are possible.
Setup
For some reason I could not get my SMC2804WBRP-G router working wirelessly with it. It worked fine wired - in fact wired setup was extremely simple, taking under a minute. I attributed my wireless setup problems to poor router firmware and changed my router to a ubiquitous Linksys WRT54G, which works perfectly, including with 3rd party DD-WRT router firmware.
I was unable to consistently get the unit to operate with SSID broadcast disabled, but it worked well with a 63-character WPA passphrase and a fixed IP address.
I had installed the software earlier to familiarize myself with the UI and the Squeezebox hardware using the SoftSqueeze software emulator, so once I solved the initial wireless networking problems and connected it to my home theatre receiver, that was it.
Operation
The Squeezebox is unlike any device you have ever operated. Simply put, everything is "tweakable"! You can change nearly everything about how the unit operates. Some of this is through the hardware interface, some is through the software which I will cover later.
The menu system is very intuitive and easy to follow. The menus are arranged "horizontally and vertically". You scroll around them using the remote's cursor buttons. The first smaller display line shows which menu you are in and how many items are in the menu (i.e. "1 of 8") while the menu item itself is described on the large second line. You can scroll through the items in the menu using the up and down cursor buttons. Once you find an item you want to enter, you scroll the cursor to the right to enter it, or to the left to go back to the previous menu. It's very easy to navigate around the menus, and the "drill down" structure feels very natural.
The unit really has two modes, playing local files and Internet radio through SlimServer, and playing Internet radio through the Internet-equivalent of SlimServer, SqueezeNetwork. When using SlimServer, you browse or search through the music stored on your PC or on your local network. On the player, you can browse or search by artist, title, genre, filename, whatever...it's all tweakable.
When browsing, you can sort through them one-by-one or you can narrow it down by typing in characters, either by scrolling up and down to increment/decrement letters or typing them in by repeated presses of a remote button like you would on a cell phone (1=punctuation1, 2=abcABC2, 3=defDEF3, etc.) Searches require at least one letter of text input. You can play music you're interested in one file at a time or you can add them to the device's playlist. You can play back pre-made playlists or you can save playlists you make for the device.
SqueezeNetwork searching and browsing works similarly, although searches are limited to genre and stream name.
Other menu items accessible through the hardware in SlimServer mode include settings such as language, screensaver when playing, screensaver when not playing, screensaver when idle/off, time format, long date format, alarm settings, library information, player information and server information. Menu items in SqueezeNetwork mode are limited to language, screensaver when playing, screensaver when idle/off, time format, long date format and alarm settings. You can also access RSS Feeds, Favorites, ambient sounds and a massive live music archive in SqueezeNetwork mode.
The unit supports an impressive range of file formats. Some are decoded natively while some are transcoded by SlimServer on-the-fly and passed to the device. The unit plays MP3, AAC, Ogg Vorbis, MP2, MusePack and WMA lossy formats, AIFF, WAV and PCM uncompressed formats with DTS pass-through, and Apple Lossless, FLAC and WMA Lossless formats.
When you are playing a file, the screen is the "Now Playing" screen. The first line will display "NOW PLAYING", followed by number of items in the playlist (i.e. 1 of 12). The Artist and Title are displayed below in the very large second line, and guess what, the data it displays can also be changed. If necessary, the line will scroll to display all the characters. The "NOW PLAYING" screen can be reconfigured as follows through repeated presses of the remote's "NOW PLAYING" key:
• artist and title only;
• artist, title and digital VU meter;
• artist, title and small spectrum analyzer;
• artist and title superimposed on a full-width spectrum analyzer.
Each screen can be used alone or with a progress bar, time remaining bar or buffer fullness indicator.
After 30 seconds, the screensaver activates. Again, there are many screensaver options and you've already seen the two most impressive, the analog VU meter and the full-width spectrum analyzer. You can disable the screensaver or adjust the time to activation.
The screen has 4 brightness levels and can use separate levels in playback, idle and off modes. The text size can be altered so that both lines are the same size, the second line is much bigger than the first, or the second line occupies the whole screen (you'd be able to see this font from forty feet away!) The text sizes can be set individually for on and off/standby modes.
And the sound quality? In a word, incredible. Much better than a CD player in my opinion. I conducted comparison tests between the optical digital output and the analogue output since, as I indicated, the unit's DAC is at least as good as those in my A/V receiver. However it seems my receiver does not handle analogue as well as digital. The digital output was crystal clear and clean but slightly bright (grating treble). The analogue sound was not overly bright but slightly muffled in the vocals. I preferred the digital connection even though the high treble can be irritating at high volumes.
The unit's headphone output, which uses the Squeezebox's DAC, sounds fantastic. Much better than the analogue connection to my receiver. Since the Squeezebox includes a volume control for the analogue outputs, it's perfect as a headphone source or with powered speakers.
Once set up, the unit experienced no wireless connection problems. Signal strength is 80-85% and remained so even when my wireless laptop ten feet away was down to "fair" signal strength and a 1 Mbps transfer rate. The buffer fills quickly at the start of a song and for files less than 5 MB in size it can store the entire song in the buffer. The buffer then slowly empties throughout play and is refilled when playing back the next song. I have not encountered any sound dropouts caused by poor wireless bandwidth or buffer underruns, even when playing 1 Mbps FLAC files.
The unit does not go "off" as you would expect. Instead it goes into standby, and the screen will only go off if you select the "None" screensaver. The unit is effectively paused and will start playing right where you left off when you take it out of standby.
Regarding the remote, my Marantz RC1400 universal remote handles the Slim Devices remote's IR codes perfectly.
Software -SlimServer
Note: The software is in rapid, active development. I am reviewing SlimServer 6.2.1, which is the latest stable build at the time this review was written.
Slim Devices' SlimServer software was made open-source right from its start in August 2001, before many of today's high-profile open-source projects. It's freely available for everyone to try. It works in Windows, Mac OS X and Linux since it's coded in Perl with an SQLite database, and it has useful features even if you don't own a Squeezebox™ since it streams your audio files throughout your network or over the Internet.
The streams can be played back over any software audio player capable of playing streams, such as Winamp or foobar2000. You can even play it back using the free "SoftSqueeze", a software emulation of the Squeezebox™ written in Java.
SoftSqueeze.
The server's interface is like any Web page and can be accessed over your local network by starting up any Web browser (it works equally well with IE and Firefox for me) and locating the URL http://:9000. Of course, this port can be changed if desired. The machine actually running SlimServer has this interface come up automatically and points to "localhost" instead of its IP address.
On the machine actually running SlimServer, a tray icon can be used to start and stop SlimServer. Starting SlimServer takes about 15 seconds on my Intel 2.8C/512 MB machine with over 1100 songs. Once SlimServer is started, the Home Web page loads:
SlimServer Home Page.
On the left side of the screen is the Server portion. To the right is the Client portion, the player. You can select from multiple hardware and software players using the drop-down list. You can browse and search music or Internet radio streams in the server portion and load it to the player.
The Web interface can be reskinned and the program comes with 13 skins. For all players, you can skip, play, pause or stop, repeat one file, repeat all or turn repeat off. You can shuffle by song or album, add or remove songs, save, download or clear the playlist and select which song you want to play. For Squeezebox's™ and SoftSqueezes, you can also remotely turn on the player and adjust its volume. Regarding the volume, note that "this one goes to eleven!"
New Music lists your music collection sorted by the time they were added, with the most recent first. Random Mix places random files on a continuous basis to your playlist. You can select files from certain genres, artists or albums. You can also set alarms, either the same one every day or a different one each day. As the alarm music, you can choose either from a playlist you've made or a random album, artist or song mix.
The software can be used to tweak just about everything in Squeezebox's™ and SoftSqueeze players, even esoteric items like scroll rate and scroll speed. You can decide what items appear in menus, where they appear, and select and control everything you can with the remote.
SlimServer Player Settings
The software can handle multiple players and they can each have their own settings. You can see all of mine listed in the home page under "Settings". All Squeezebox's™, SoftSqueezes and software players will be initially recognized by IP address but can later be given unique names to differentiate them. SlimServer will remember what items were last playing in each player.
Multiple hardware and software players can be synchronized to play the same material at the same time, and hardware players can be set to power-on simultaneously for whole-house audio systems. The software also has good security provisions. Access to it can be password-protected and you can set it to block command-line interface and HTTP requests from all but a list of allowed IP addresses. There is also medium or high protection against cross-site request forgery attacks.
SlimServer performed well on my setup. The most intensive operation you can make it do is rescan the music library for changes. Rescans take 15 seconds for my 1000 songs. CPU usage rises to 50-60% during this period, but playback on the Squeezebox™ is still flawless and uninterrupted.
Rebuilding the library from scratch and rescanning only takes a minute or so. Even during rescans, SlimServer's Web page generation is quite fast.
SlimServer also uses plugins contributed by the community. The plugins cover items such as new screensavers, games, visualizers, Internet-derived data like weather, sports scores and TV listings and feature enhancements.
Software - SqueezeNetwork
SqueezeNetwork is the Internet-based equivalent of SlimServer and can be accessed from any Internet-connected PC at www.squeezenetwork.com. The feature is powered by Linux servers Slim Devices maintains which run modified SlimServer installations. When you first set up your free SqueezeNetwork account, you enter in your Squeezebox's™ unique PIN which associates your Squeezebox's™ MAC address with your account.
You can then access SqueezeNetwork directly from your Squeezebox™ - there's no need for SlimServer and you can turn off the PC running SlimServer if you wish. SqueezeNetwork allows playback of the thousands of Internet radio streams, a massive live music archive, ambient sounds and RSS feeds as well as remote control of the player and its settings.
SqueezeNetwork Favorites Page
As you can see, SqueezeNetwork allows you to pause or stop the stream, turn your player on or off, adjust the player volume and shows what is currently playing on your Squeezebox™. This screen shows your favorites since you can't save a playlist as this is all streaming content.
You can also directly play one of your favorites, reorder your favorites, delete them and add new streams to your favorites list, giving them custom names.
You can also add or delete streams using the player, although any streams added this way have to be through one of the prearranged groups of streams available on SqueezeNetwork. These groups are SHOUTcast, Live365 and radioio, as well as a selection called "Slim Devices picks", a rotating collection of streams. The Web interface doesn't have this limitation, allowing you to add any stream to your favorites.
SqueezeNetwork is much like SlimServer in that player settings can be set within the software:
SqueezeNetwork Favorites Page
This is a much more limited feature set than what you can change with SlimServer, but I've got to admit, there's something very cool about changing a setting on a Website in California and having your own player mysteriously respond without any intervention from the remote!
The Squeezebox™ operates differently on SlimNetwork than on SlimServer in that there are fewer options. Yet there are still enough that it's a fully capable Internet radio player. You can also add and remove RSS feeds. This is a neat option, and you can select an RSS feed screensaver either during playback or when the unit is off, but unfortunately it's mostly for novelty as it can only display headlines.
The Company, the Community
No discussion about the Squeezebox™ would be complete without some comments about this unique company, Slim Devices. Never before have I bought something from a company that seems to be so much...well, so much like me! A comment was recently left on their forum from an ecstatic user like myself that described the company like a group of friends making cool stuff just for us. I couldn't agree more. This small company started in a humble way.
Several company practices reinforce my opinion of them:
• they do not advertise;
• they do not sell in retail stores;
• they keep their price low yet use top-quality components;
• software updates, firmware updates, SqueezeNetwork, all free;
• all old products still supported, including the SLIMP3™, now three product
generations behind.
The software updates are frequent and can offer substantial new features. Firmware updates are included with each release but keep in mind that the device is mostly software-powered. Therefore changes in the software can dramatically affect how the device performs and what it can do.
The software is open source and the forums are active with Slim developers and enthusiasts from around the world. The CEO drops in almost daily. Experiencing a problem? Submit a bug report and it will probably get addressed in the next software release - there's usually one or more per month. Have a suggestion for a new feature or want to see something changed? That can be accommodated as well. Just try that with any other consumer electronic device.
Negatives
Can you have your cake and eat it too? Not quite!
The Squeezebox™ 3 and SlimServer are very complex pieces of technology. They operate very well, but not perfectly. I haven't been able to get the unit to actually go "completely off" in SqueezeNetwork mode as I expected it to - the standby date/time screensaver always comes on, even though I had selected the "None" screensaver in both the Website and the hardware.
SlimServer is a fairly well-written application, but it uses a fair amount of memory. It normally consumes 60-80 MB, and the tray application that can switch it on and off uses 6-7 MB more. This is better than some version 5 releases that consumed 100 MB or more, so there has been progress. I don't find this to be a problem as I'm not normally using my PC when I'm playing my Squeezebox™ 3, and even when I am using this PC I haven't experienced any problems. I don't run SlimServer at all times anyway.
There are some minor functionality glitches that pop up from time to time. For example, my screensaver when playing does not come on occasionally. I set it through the player interface and it comes back every time.
Tagging MP3s properly is very important with SlimServer. I standardized on not using the album tag. This worked fine with SlimServer 6.1.1 but with 6.2.1 all my songs were grouped together under one album ("No Album") and I could no longer search by artist. I added a few album tags and rescanned and it's working well again although the link still indicates "705 songs by 370 artists in 1 album" if I'm looking for just one song. However the song listed is correct. Others were having this problem as well and a bug was created. This is partially my fault, but SlimServer 6.1.1 worked fine with it - 6.2.1 does not.
Conclusion
Can it really get any better? Not much! The unit's stunning looks, high price/performance ratio, its unbelievable sound quality, its supreme flexibility, the outstanding support from the company and the community, its continuously growing capabilities and the pure geek factor make this one of the coolest gadgets around.

The Software
The Slimserver 6.2 software (firmware) that I downloaded installed in a snap. When you see it on your computer screen, it isn't much to look at. It is very utilitarian in nature. When you start the interface program on your computer, up pops a new session in either Foxfire or Internet Explorer (or whatever your Web surfing front end is).
On the left are the basic menus, on the right are your music files (assuming you've ripped some music to your hard drive). Navigating the software is easy enough.
Everything is easy to find and adjust or tweak, just don't expect some snazzy GUI software and you won't be disappointed. Don't get my comments wrong, the front end software is completely usable and does exactly what you tell it to do. Besides, the software was written in an ‘open' code so that anybody familiar with it's language could write small add in programs. You'll find a host of nifty ‘plug ins' at the Slim Devices Website.
In my case, my server is upstairs and my listening room is in the basement. The little Netgear wi-fi router that I use puts out the signal just fine for my connection. When you actually start the player in your system, you can use the remote control that is provided with each unit.
The remote is your typical plastic cased infrared device that is specific to the Squeezebox™. On the remote you can control the volume, scroll the onboard menus (which are many), play, pause, go forward or back, or any number of other preprogrammed options Slim Ddevices have setup.
Although there are several other interface devices (remote controls) that can be utilized like a wi-fi enabled PDA, to control your music, the factory remote does just fine. It will take you wherever you want to go.
Just in case you were wondering, you can attach more than one Slimserver to your network. I've currently got two installed, one Bolder Cable modified (that I'll review in the next installment) and one bone stock SB3. When you have additional Squeezebox's™ installed, they are each controlled independently.
In other words, you can play different tunes in the individual SB's, they aren't synced or ‘master slaved', they operate totally independent of each other. Very cool.
Another nifty feature that the Squeezebox™ has is you can set screen savers to pop up while playing music or when the unit is powered down. The screensavers can vary from VU meters to RSS feeds from your favorite Website.
Guess what? Enjoy the Music.com has just the feed for your new Squeezebox™ as we now offer an RSS / XLM feed. I thought I'd throw in some shameless self-promotion to try to suck up to the Boss... Hi Steve! (Editors note, said in good humor: the stack of non-sequential $20 are behind the rock that looks like it down.
Ripping And Compressing Tunes
The next step was to download what is commonly accepted by digital audiophiles and computer geeks alike, as the best ripping software. Exact Audio Copy (EAC) is an open source, freeware program that can be downloaded at a number of sites. EAC isn't the most intuitive software I've ever played with before, but it isn't bad either.
I'd like to suggest that if you plan to use this that you do some searches on Google and the forums on how to set it up properly. Hydrogenaudio.com is a good place to start. There are all kinds of settings that the laymen (read = me) won't have a clue as to what they are, or mean. Things like Offset, Gap Settings and weirdness like that.
Once you rip your CD to WAV files, you now must choose one of the lossless compression schemes supported by the Squeezebox™. Me, I chose FLAC (Free Lossless Audio Compression).
This is a separate program that compresses the WAV file to save space on your hard drive. I'm getting about a 40 percent reduction in file size over the raw WAV format. As it stands, I've got 236 albums ripped containing 2442 songs with a playing time of just over 198 hours and this takes up approximately 75 gig of drive space.
If you are truly anal about ripping your CD's to a hard drive, there are several programs that will do a bit-by-bit comparison of the original file to the compressed file so you can feel better that you haven't lost a half dozen 1's or 0's somewhere in the translation.
Me, I could care less. I've talked to several people who have tried the comparison and the audible difference is imperceptible when you pick back up those few missing bits and bytes. Not to mention, the comparison then re-ripping required all takes time. With a thousand CDs and counting, life is too short (for me anyway).
All told, between ripping a CD to your hard drive and compressing those files, it takes about fifteen minutes per CD. Obviously, this time will vary on a number of factors. First, your processor speed, next is your CD drive speed and compatibility with the FLAC front end software. Now that I'm up and running, lets talk about some music.
Tweaks
Before I go in depth about how the SB3 sounds, there are a couple of things that you will want to know first regarding the stock unit. First, the stock switching power supply is woefully inadequate for the critical listening that we audiophiles do.
Fortunately, a cheap easy substitution of a $7, 5 Volt 1.5 Amp (regulated) wall wart brings a significant gain in resolution. If you want, you can go for a supped up 5 Volt regulated power supply like Bolder Cable offers or a battery power supply as in the one Red Wine Audio builds. I'll be auditioning each of these in the second of this series on the Squeezebox™ 3.
Next is the software version that you use to drive the digital volume control on the SB3. Keep in mind the volume control is done with an algorithm before the DAC. There are no volume pots on this unit. It's all done with software and a remote. That means that depending on the software version, the unit can sound slightly different.
I happened to pick this one up from some of the guys on one of the audio forums. They had mentioned that the new 6.2 firmware had been released and several of them upgraded. They began to notice that the units didn't sound quite as good as they did prior to upgrading firmware.
In turn, one of them rolled back a portion of the firmware to the previous version and found that the great sound reappeared. Sure enough, I did the same thing and it definitely sounded better than the new firmware.
Since those discussions first popped up, the software gurus at Slim Devices have incorporated some new programming language into the latest firmware update that addresses this issue. The truly great part about this little faux pa is that when the issue popped up, within three weeks (or so) the company had addressed the issue with a downloadable firmware upgrade. Lets see one of the majors try that one on for size.
Listening To Streaming Music
I know all of you hardcore audiophiles out there are cringing at the thought of this but read on, trust me. According to Sean, there are over 200 streaming stations currently available through the Squeeze Network. The quality of the streams varies.
Many of the streams are at 128bps stereo at a 44.1kHz. This is far from the ultra low rez MP3 streams you might expect. As I mentioned before, you can always manually type in a Web address and get nearly any feed out there. That makes the total number of streaming stations available over 10,000.
Granted, this isn't like listening to a CD or piece of vinyl but it's WAY better than the heavily compressed FM that gets broadcast in many local areas (or at least my area). And to top it off, there ain't no damned commercials. It's pure streaming music, interrupted (with the exception of the occasional station ID). The radio of the future is here today.
Myself, I've gotten hooked on a couple of different streams. One is the Shoutcast Digitally Imported European Trance Techno Hi-NRG station. The others are just about anything radio streams.
Now, if you've ever listened to streaming music on your computer, you know that there are a limited number of users that can be on a stream at any given time. Keeping that in mind, you may run across a station that you can't log onto. Hopefully isn't one of your favorites but if it is, there are (no doubt) numerous streams that will trip your trigger.
In listening to the streams (at least with the DirecWay satellite), I occasionally get a momentary interruption or hiccup in the feed. Heavy weather is completely disruptive to my stream but I guess that's my fault for living in an area that doesn't have DSL or cable modem. In the same vein, my DirecWay has a screaming fast download speed of over 1.3mbps.
As an additional feature, Slim Devices has included what they call the Squeeze Network as a menu option on the SB3. The Squeeze Network allows you to listen to streaming music without having your computer turned on. That's a pretty cool feature providing you've got a direct pipeline to the Internet via your network server.
Getting back to the sound quality of the feeds. When you lock onto a station like radio Classical that streams at 128kbs/44.1kHz, the sound can be quite impressive. Granted, it isn't lossless but can be extremely satisfying.
The sound is fairly natural with an acceptable amount of digital overtones of artifice. If you aren't doing critical listening, the stream is completely enjoyable. If you are reading a book or doing some work around the house, or even trying to find some new music to sample these 128kbs/44.1kHz streams won't stand out as being inferior in the least.
With an external audiophile DAC the highs are nice and extended without being too splashy, the midrange is full and almost believable and the bass is quite taught. The sound of these feeds don't give you the feel of "being there" as a good piece of vinyl or a quality CD does, but it is FAR better than you might think.
I'm pretty picky when it comes to sound and I find myself listening to the streams quite a bit, and I enjoy them. Of course, if you lock onto one of the low bit rate streams, it sounds pretty crappy but you always have alternative streams to listen to.
One of my favorite things about the streams is the fact that I get exposed to new music. Stuff that I never hear played on commercial radio, even on my Sirius feed in my car. Listening to radio, I have found more new music over the past two years of listening to it in my office and at home than I ever would on my own.
Just like right now, I'm listening to Stacey Kent. She's a female Jazz vocalist who has a more than attractive style. I kinda like her. In turn, I can't say that I've ever listened to her before. This makes me want to go up to Amazon and sample (and maybe buy) some of her music.
The best part of all, these are free streams.
Commercial Radio Is Dead
A while back I had planned on doing an expose on the commercial radio industry. I had planned on writing a dissertation that let people know just how corrupt the music industry and commercial radio truly are (think the Evil Empire, Clear Channel Communications).
I was going to give you interviews with a couple of local, long time radio DJ's that would spill some little know information about the industry (anonymously of course). I planned on citing sources that would make you despise the music industry even more than you probably already do.
But then at a concert, I ran into one of those un-named DJ's and we started talking. Eventually the conversation turned to my planned article. We talked for a while between the artists sets and Rich (the DJ) said (paraphrasing), "Everything you mentioned is right, but lets look at this a slightly different way.
Today, we are exposed to more music than at any time in the past. You and I grew up listening to one or two FM stations. Now, everywhere we turn we have music, from the commercial radio stations, to Sirius and XM, to nightclubs and concert venues, to MTV and VH1, to the Internet. The Internet alone has thousands of streaming feeds of music. No matter what your tastes in music, you can find it on the internet."
That got me thinking. Rich was exactly right. I'm not normally a negative type of guy. Occasionally something sticks under my craw (like the music industry) but rather than focusing on that, if I can find a viable alternative, I'll definitely take that path. Such is the case with streaming music and the Squeeze Network.
Here we have in front of us a wonderful piece of technology that can connect us to one of our first loves, music. Best part is its music in its purest form, non-hyped, non-commercial, and nobody has been bought and paid for by the music industry and its cronies (at least none that I know of). These streams really remind me of the Golden Age of FM radio.
Listening To Ripped CDs
I'm going to start off by hitting you with my long time rant (feel free to skip this paragraph if you wish). Just because you can rip a CD to your hard drive does not give you license to go knock on your buddy's door and borrow his entire CD collection and start ripping them.
If you own the CD, it is perfectly fine (and legal BTW) to rip it to your heard drive. If you don't own the CD and you rip it, that is stealing... period.
The Congress of the United States allows you to make copies of music you have purchased providing you don't sell them or give them away (that is a crime too). Besides, buying a CD from your favorite artists makes sure that they are happy and healthy, monetarily. If they are happy, they keep making music.
If they aren't happy, they give up and go sell shoes at a mall or something to make money. So bottom line, don't rip a disc you don't own or download ‘free' music. You wouldn't want somebody taking the fruits of your labors for free would you?
Oh, and BTW, downloading music from allofMP3.com is officially the same as stealing music. Forget the fact that you pay by the megabyte to download files; allofMP3 isn't paying royalties to the artists whose music they are selling.
The IFPI (International Federation of the Phonographic Industry) is currently in negotiations with the Russian Government to shut that site down and bring the offenders to trial, and rightly so.
OK, so I went two paragraphs, sorry.
Let us talk about the sound of the stock Squeezebox™ playing ripped CD's. As I mentioned earlier, the SB3 really needs a power supply upgrade if you plan on using it in your multi-thousand dollar two channel audio rig.
On the typical consumers Big Box system, you probably won't notice much of a difference but on the gear that we play with the difference is immediately noticeable. A cheap, regulated power supply (wall wart) that delivers 5 Volts at 1.5 Amps or better will give you better dynamics, cleaner highs, firmer lows and far less hash than the switching power supply supplied with the stock SB3.
Plus, a cheap regulated power supply costs all of about $7. Don't think, just buy one, honest. Now, when you get into custom built power supplies like Bolder Cable sells, everything gets tons better but I don't want to give away too much. I'll save that for the next instalment.
After giving the stock player about 100 or so hours to completely break in, I gave it a critical listen. Although the stock Burr Brown DAC seems to be a nice feature I'm afraid that the opamps and other components used in the analog signal path aren't quite up to the hardcore audiophile standards we are used to.
Don't get me wrong, the unit sounds better than the vast majority of the entry level players out there (read = $300 or less). In fact the SB3 may even compete with some players that are slightly more expensive but unfortunately I haven't fooled around with that price range of player in a while.
What I can say is that the onboard, analog output stage of the SB3 doesn't do anything wrong. It's not aggressive sounding in the least. It has a very laid back presentation. The soundstage is rather flat and two-dimensional.
Placement of the instruments and vocals are nice. The lows are nice and taught. The mids are decent, although veiled, and the highs are polite and slightly rolled. The sound quality is extremely smooth and infinitely listenable. All in all, not too bad considering the overall $300 price tag.
Where this little unit begins to really shine is when you add an external DAC. In my case, I plugged in an old CAL DAC Sigma. As you all know, not the greatest DAC but not the worst either. After giving the digital output some time to run in, the Squeezebox™ started to show some serious signs of life.
The insertion of a mediocre DAC like my old standby CAL DAC Sigma II (tubed) makes a marked improvement in the sound. The soundstage increases in depth and width, the music takes on more "life" as a whole.
Listening to one of my favorite performers, Pat Metheny and the album he cut with Dave Holland and Roy Haynes titled Question and Answer, the music nearly came to life. On this particular recording, Roy Haynes drums are superbly mic'ed.
When Roy snaps the snare drum or does a mini-solo, you almost feel as if he is in the room with you. I started to get a real sense of how good the Squeeze Box could become using the digital output and the CAL DAC. I can't wait to plug in a true high end DAC into this little treasure.
As I listened to other music that I had ripped, I found that the addition of the external DAC was the way to go. Everything came much closer to what we all love about high-end audio.
I do have to say that it still lacked a bit though. There was still some slight veiling to the overall presentation partially due to the stock digital output and part due to the CAL DAC. It wasn't horrible, but it was there. Not to worry, remember those Mod guys I mentioned earlier? They've fixed that (and inexpensively too) but I'll save that for the next installment.
Quirks (Sort Of)
Pause function on the remote control can be a bit abrupt. But think about what the pause button does, it stops the stream (and maybe the hard drive too?). In turn you get (on occasion) a thump. That thump is no louder than the music that is playing so there is no fear of killing a speaker. It might be nice if in the next software release that the software guru's wrote a nice fade out, fade in algorithm for the pause function.
Since hard drives are limited to (about) 400 gig for an internal drive, it would be nice if on the next software release the ability to more than one music folder were incorporated. As the version 6.2 software stands, it can only read a single directory.
Also, if you are using a laptop to communicate to your music server (and its folder), the network location must be typed in manually. The Slim Server music folder settings don't support reading across a network automatically. Again, this isn't anything that the software gurus can't add in future releases.
So Why Does This Sound Better Than a Standard CD?
If you read my articles on a regular basis, you know I'm a hardcore analog kinda guy. I love the sound of valves and vinyl but this little interface device now has me listening to more and more ripped CD's. The sound of a CD doesn't sound like a CD any more. It's hard to explain, much yet rationalize (for my pea brain).
The only thing that I can figure is that now on each playback of a CD, no longer do we have all of the issues associated with a transport mechanism the pick up (optics) and error correction (and resulting jitter).
Ripping CD's to your hard drive, there are no more read errors on the fly, no more laser beams reflecting inside the CD players case causing what ever they cause (think green Sharpie's and blue LED's inside the case), no more 500 RPM (and less) vibration issues of the transport shaking the rest of the electronics inside your CD players case, no more issues of the CD not being perfectly balanced or being slightly out of round causing read errors.
From read errors caused by micro pits and imperfections on the glass master that are magnified by the manufacturing process, to additional pits in the plastic formed during the manufacturing process, all of these contribute to jitter.
When you rip music to your computer, the ripping software utilizes a second, more intensive level of error correction with the CD/ROM standard (IEC 10149) which the typical music CD player excludes. This ripping software differs from music playback software. When you are making a bit for bit copy of ones and zeros, it is crucial that the copy be exact.
Otherwise, you end up with a corrupt file. The ripping software and computer looks at the music file as a data file. If a computer data file is corrupt, it doesn't work, where if a music file is corrupted while you are playing it, you get a pop, hiss or maybe a slight reduction in definition. Music playing software (both read and write) isn't mission critical to a CD player or computer.
Once your CD/ROM drive has extracted all of those little ones and zero's to your hard drive, you have just eliminated all of the problems inherent with a transport leaving you with a pure, bit for bit, digital stream that is then converted to the analog domain (in the form of your favorite DAC). The end result is you have a more pure, less harsh sound.
If you've ever listened to an extremely expensive CD player ($3,000 to $5,000), you know that the sound is much more 'analog' than that on a low to medium priced CD player. Ripping CD's to your hard drive, then using the Squeezebox™, a quality power supply and an external DAC now gets you much, much closer to the sound of a true high end CD player.
Here is another biggie in my eyes. The Squeezebox™ has upgradeable firmware. In other words, the software program that makes this thing work, is constantly being upgraded to give it better performance. Slim Devices has a forum where you directly communicate with the software developers and the owners of the company to report bugs, make a suggestion or just talk with other Squeezebox™ owners.
When a firmware upgrade becomes available, you just download and install it. It's that easy. If you don't mind playing with pre-releases or Beta versions of future firmware upgrades, you can do that too. Since thins software is Open Source, there is a myriad of ‘Plug Ins' that are (or will be) available for the Squeezebox™. The ones I'm waiting for is the Up Sampling and the Polarity Reversal plug ins.
In The End
I haven't been this jazzed about a piece of new gear in a long, long time. Don't take my comments about the stock analog output out of context. When you add a decent external DAC and a good power supply, this little piece of technology can sound wonderful.
Using these tweaks, this unit easily competes with CD players costing well into the thousands. As much as I love the sound of my AH! Njoe Tjoeb, I have to say that the combination of the Squeezebox™ with a good power supply and a decent DAC, the sound is much smoother and more natural sounding.
The tweaked Squeezebox™ has brought my music on CD several steps closer to the analog domain. I'm not raving here, I'm being dead serious when I say, when you roll in mods to the stock Squeezebox™ as we'll be talking about in future articles, and we really have got a serious piece of kit for not much money.
If you've ever wondered just how good computer based audio can sound, I'd like to suggest trying the Squeezebox™ 3. Be sure to pick up a decent power supply and I highly recommend using a quality external DAC.
The quality of sound you get from this little gem will depend on your DAC (obviously). Even with the stock unit and a decent DAC, you are likely to find a serious improvement over what you are used to hearing from CD's and conventional players. Again, the reason (as I see it) all boils down to bit for bit digital copies of the music and the resulting reduction of jitter.
The Squeezebox™ is extremely easy to use and is highly configurable to suit your personal preferences. You have all of your CD's right at your fingertips, organized in any fashion that you wish. And let's not forget the fact that you get some pretty decent sounding streaming music as side benefit of the Squeezebox™. The Squeezebox™ is definitely worth checking out.
My Ratings
As you will read below, I have included a second column that shows the ratings of the Slim Devices Squeezebox™ 3 with an external DAC and a regulated power supply. I have chosen to do this because of the drastic improvement in the sound quality gained by utilizing the digital S/PDIF output provided on this unit.
The DAC used for these ratings was an unmodified CAL DAC Sigma II. A regulated 5 volt, 1.5 amp power supply was also used in the Modified column. If you were to use a better (or lesser) DAC, the scores would go up or down accordingly to the quality of the piece chosen.

Upgrade Squeezebox™ 3
I got the last capacitor for the analogue stage upgrade in the mail today, I had a couple of hours of spare time so made a start. DE-soldering of surface mount components has got to be the worst job!
It's slow painstaking work avoiding damage to pads and tracks, and this took the longest part of the job. A slight modification to the IC adapter was necessary to avoid hitting a capacitor otherwise reassembly was simple.
Plugged it in and away it went (sometimes I surprise myself!)
Nice sound immediately and I'm sure it's only going to get better once the Elna's burn in!
I was surprised how sturdy the adapter is, there was no issue plugging in the IC, so chip rolling would be extremely easy.
A worthwhile modification? Yes I think so!

Bolder Cable Digital and Power Supply Modifications
Wherever you go there you are…
I stumbled into computer based audio by way of using an iPod as my portable music player and if you are reading this chances are you did too since Apple has upwards of 80% of the retail market for MP3 players.
The iPod is a fantastic device for portable audio, never skips, decent battery life in the newer versions, and when fed lossless or uncompressed files and run with some decent headphones sounds very good. When I got my first iPod I was geeked and thought it would be great to have this kind of convenience of organizing music in my main system.
I quickly learned however, when hooked into my main rig for critical listening it sounded quite poor, and I could hear all its warts plainly when it was not competing with background noise in a car or plane.
I began to investigate alternative means to get files from my computer to my main system and after researching the available options I decided to purchase the Squeezebox™ 3 based on the fact it had a decent quality DAC, excellent display and interface, and a coax SPDI/F digital output.
At only $299 for the wireless unit it didn't seem like a big risk compared to many other components I have bought in a fit of lust and later divorced in disgust.
Squeezebox 3... Sexy tech
Initially I was planning to use the Squeezebox™ to augment a traditional disc player for sheer convenience. I have owned a few quite nice sounding units including the Ayre CX-7e, Electrocompaniet EMC-1UP SE, and Arcam CD23, and I was using a Bel Canto PL-2 feeding a Benchmark DAC-1 at the time I purchased the Squeezebox™ with satisfactory results.
I first tried using the analog outputs of the Squeezebox™ directly into my preamp, and while acceptable for background music, it did not have much life. Dynamics were poor, frequency extremes were missing, and there was a veil over the music.
I moved on to feeding the Squeezebox's™ digital output to the Benchmark and this setup showed serious promise. Music emerged from a very quiet background and lacked any digital glare nearly equaling the overall performance of the PL-2/DAC-1 combo.
When I factored in how nice it was to never have to leave my chair to change discs, the PL-2's time was up. Following it out the door of my listening room was my monstrous CD rack, no longer looming over me from the corner of my room like a tidal wave of jewel cases, and I was not sad to see it go.
Taking the Plunge
Having spent days ripping music via iTunes, I was now wed to my hard drive come hell or high water and it was time to get serious. Bolder Cable is based just fifteen minutes from my house so it was an easy decision to investigate their modification services for the Squeezebox™ 3.
Bolder offers several types of mods including extensive analog output upgrades but since I was planning to use the digital output to feed my DAC-1 I requested only the digital mods be applied.
I also purchased the Elpac regulated linear power supply that was recommended by Wayne Waananen the head honcho of Bolder Cables as they do not carry the unit, and once it arrived I gave him the Squeezebox™ and power supply to work his magic on. In the meantime I listened to my unmodified Squeezebox™ to get a good handle on its sound and prepare for a direct comparison.
The glamorous looking Elpac power supply
Wayne's modifications to the Elpac power supply include replacing the stock diodes with HexFreds, replacing the smoothing cap with a higher capacity and higher quality Panasonic, replacing the reservoir cap with a very low ESR Panasonic FM series, and adding a Black Gate NX series cap as a bypass across the output of the regulator.
Their Squeezebox™ 3 digital mod includes replacing many of the main input power supply capacitors and digital buffer power supply capacitors with higher value low ESR versions. BlackGate NX caps are used throughout the circuits.
The power supply cap to the digital buffer chip is replaced by a BlackGate NX and the signal path to the digital output jack is rerouted. The digital output jack is replaced with a 75 ohm, WBT NextGen, gold plated, copper RCA. I don't know what a lot of this stuff does but it sure sounds good, and the new WBT connectors are fascinating to look at.
The power supply mods will set you back $100 plus the cost of the Elpac, and the digital mods are $200 plus the cost of a Squeezebox™, both prices exclusive of shipping.
Wayne cautioned the modded unit would need some significant break-in to achieve its full potential. I found this to be true as for the first several days it actually sounded worse than the stock unit, lacking body and seeming somewhat harsh sounding. Since there are no moving parts to wear out I was not worried about leaving it on nonstop for over a week while I was out of town, and when I returned my patience was rewarded.
The unit had taken on a lushness and body that was missing in the stock unit, and the weight and extension in the bass was much improved. I am not sure if I am a bass freak since no one has ever called me that before, at least not to my face, but I do like plenty of slam and extension during my frequent excursions into industrial and electronic music.
The modified Squeezebox™ has excellent bass slam, and when I ramp up the volume on tracks like Goldfrapp's Black Cherry or Massive Attack's Mezzanine it delivers a physical as well as audible punch to the gut without loss of control or pace. Despite the increase in heft, acoustic bass and male voices were never overcooked, and overall coherency was improved.
In addition to the added low end prowess the midrange and treble gained greater aptitude and female vocals in particular became much more lifelike. Listening to Vienna Teng on Dreaming Through the Noise or Neko Case on Fox Confessor Brings the Flood, it seemed like I was listening to the performer and not a glossy facsimile as is often the case with digital sources, and the micro-dynamics of their voices came through more clearly.
The midrange balance with the modded unit in my system leans to the warm side, but this is due in part to my Aesthetix Janus with new old stock tubes as well as the DAC-1 itself which is not quite as incisive or detailed in the midrange as it is in the treble and bass.
I prefer an immersive and forward soundstage, and a pronounced midrange to mid-treble typically puts mud in my applesauce to say the least. The unmodified unit added an often times unpleasant emphasis to these frequencies, but depending on your tastes you may miss this energy on some tracks.
Personally I much preferred the more polite presentation of the modified unit which reduced listener fatigue to a non-factor. I found the "spotlight" on some instruments and vocalists was less artificial with the modified unit and the image was larger both in width and depth offering a truly engaging listen.
In the upper registers the modifications allowed cymbals, bells, and synthesizer bleeps & braps both the detail and body required while avoiding the harshness and grain of the stock Squeezebox™.
My speakers have a ribbon super-tweeter and though the sound was smoother and easier to listen to it was very evident the zenith of treble extension was raised. On material such as the new self titled release by Rodrigo y Gabriela, the sound of their fingers on the guitar strings was perfectly integrated with the sound from the guitar body instead of being a distracting discombobulated noise.
In addition the modifications lowered the noise floor allowing more air and ambience from the recorded space to be heard. I found I can now listen to many discs with a significantly lower gain and still hear all the detail and ambiance. The dreaded cliché of digital sounding "analog" is about the only thing I can say, the modified unit simply allows more high frequency detail with less fatigue than the stock unit.
So are there any other good options to get my tunes out of your PC if you don't want to spend this much dough?
I compared the stock and modified Squeezebox's™ to two other methods of feeding my DAC to ensure I hadn't just fallen for the first gadget to catch my eye. First I ran the mini optical output from my Mac Mini to the Toslink input on the Benchmark.
This setup was very lackluster at first and I was ready to give up after less than three songs, then I found you could output a 24/96kHz signal from the Mac by changing system settings. Moving from 16/44kHz to 24/96kHz was an enormous leap, and the 24/96kHz sound was very dynamic with good frequency extension and a decent soundstage.
What kept the direct toslink connection from challenging the Squeezebox™ was a digital glare manifested as an annoying harshness in the upper mids and lower treble that made listening for more than a few minutes very uncomfortable. This harshness was more pronounced than on the stock Squeezebox™, and coupled with the increased dynamics I found myself wanting to run for the door on several rock songs.
While not without significant drawbacks in sound quality this setup was the value leader as the Belden mini optical to Toslink cable set me back $14.99, however an additional consideration is a controller. If you do not have a monitor in your listening room or some other form of controller for your software player, the Squeezebox™ is clearly a simpler way to manage your library.
I utilized a PDA and the Salling Clicker software to control my iTunes without a monitor and it worked quite well, but again this is a more complex solution than the Squeezebox™ and probably not one to recommend for those who find programming a Tivo box akin to putting a man on Mars.
Hagerman Technology - HagUSB.
Next up was the Hagerman Technology HagUSB, a simple USB converter that outputs an SPDI/F signal. This device is quite inexpensive at $125 and can be made from kit form for even less. I found the sound of the HagUSB to be quite pleasing and it did not suffer from the harshness that plagued Mac's optical output.
On discs like Goldfrapp's Black Cherry, the synthesized noises that were grating through the Mac's output were now tamed, and the soundstage was more laid back.
The more I listened to the HagUSB however the more I found it was a bit too pleasant, obscuring detail and noticeably softening the attack and bite on many recordings. To be fair, the modified Squeezebox™ and power supply total out at over $600 while the HagUSB comes in at a fraction of that, so considering its overall musicality it could be a good option if budget is a concern or you just want to dip a toe into the PC audio ocean.
Again one consideration is how to control your music as the HagUSB is simply a conduit to get the 0's & 1s out to your DAC. For some this is no big deal, for others it is a deal breaker as mentioned previously.
After evaluating all of these options, I found the Bolder modified unit was simply more dynamic with significantly fuller bass, a musical and less fatiguing midrange, and more delicate and extended treble.
As a final hybrid test I also hooked the stock Squeezebox™ to the modded Elpac power supply and found this to give it a definite boost in dynamics and bass, but did not present the same liquidity or soundstage of the modded unit and the treble was still a bit zingy, so my advice is to go for the full digital mods.
So how good is it?
Based on my experience with the Bolder Cable modified Squeezebox™ I would say it is a spectacular bargain when you consider the sound quality it is able to extract from your hard drive. The beauty is you likely already have a PC of some serviceable sort, and if you have a wireless network you can put the Squeezebox™ anywhere in your home and have a reference caliber transport for very little investment.
This truly appears to me to be the future of digital, and recently several very high-end hard drive based stand alone units have been introduced supporting the idea that the days of using physical discs are numbered.
Others more technically literate than I have written volumes about the potential superior performance of hard drive as a source versus compact disc due to reduced jitter, error correction, and other benefits.
It is also hard for me to fathom that I was able to replace an entire wall of CDs with an external hard drive the size of a dictionary, and a 40 pound player with a unit the size of a box of Mac n' Cheese and not lose sound quality in the process.
PC Man moves into Appleville...
I admit the main reason I bought an Apple Mac Mini is aesthetic, the thing is tiny, and it is also almost dead silent. It is also the simplest computer I have ever used and given my full acceptance of iTunes it was an easy choice for a dedicated music source.
Now for some controversy, I have ripped several discs in both Apple Lossless Compression and as uncompressed files and found I could not reliably tell the difference so to save disk space most of my collection is encoded in ALC.
This probably causes some ruffling of feathers as some feel there is a sonic compromise despite the fact that it has been proven it truly is a lossless technology, and also because others don't like being roped into using Apple's proprietary software.
Without delving into those too deep, this underlines one of the strengths of the Squeezebox™ platform, it will decode pretty much any format under the sun, and Slim Devices has provided constant firmware updates to keep up with changes or reported glitches.
For those in uncharted territory with ripping music, I have found iTunes to be the most user friendly program out there as it automatically categorizes and labels as you rip and its playlist feature is very simple to utilize (and its playlists can be utilized on the Squeezebox™).
I have used other programs on a Windows machine and although they often have more flexibility and advanced options, they are significantly more complex than iTunes for those who are not at least moderately skilled in PC geekery. No matter which path you decide to take, you will be surprised at the level of performance offered.
For anyone who has contemplated using hard drive based audio, I highly recommend the Squeezebox™ 3 with Bolder Cable Company modifications for the sheer ease of enjoying high quality digital music.
It is great when I have an entire evening to spend with my vinyl allowing time for thorough cleaning and setup, however I find myself now sitting down to listen to several different artists for 20-30 minutes when in the past I would likely not have due to the inconvenience of selecting discs and warming up a player.
Computer based audio is just coming into primetime for use in high-end audio and there are sure to be advances ahead, but the modified Squeezebox™ is a simple, affordable, and great sounding solution for anyone looking to break free from the shiny disc today.

Squeezebox™ 3 with upgrades installed by Russ
I finally got around to modding my SB3. Thanks to those who posted in this thread, especially Gary, to get me moving in the right direction. It turned out to be more of a parts removal operation. First I replaced the PS cap with a 3,900uF Panasonic FM. I then removed the op amp, the input and output caps for the op amp, and the analog RCA jacks. I installed upgraded RCA jacks and connected the DAC outputs directly to the RCA jacks.
What! No coupling caps? Well I wasn't thrilled with the option of using tiny electrolytics due to the tight spacing so I decided to go outboard with the caps. Here's what I came up with. Those are 4.4uF polypropelene clarity caps. And yes, the SB3 sounds wonderful in this configuration!

Squeezebox™ 3 with upgrades installed by Audiocom
The Squeezebox™ 3 incorporates Logitech’s fourth generation hardware. Features and most technical specifications are identical to that of the Squeezebox™ 2. A new board and chassis design are used, as well as a new remote. With the introduction of the "Duet" Squeezebox™ 3 was renamed "Squeezebox™ Classic".
The stock Squeezebox™ Classic is a convenient niche product with decent mid-fi sound. There is however far greater potential available from the stock unit, particularly when used as a digital front end via the digital output to a high quality external DAC.
Our modifications focus on reducing noise input noise, providing very low noise DC regulation, minimising jitter, and improving the quality of the digital or analogue output signal.
If you are looking to maximise digital or analogue audio performance from your Squeezebox™ Classic then our range of upgrades will take it several notches up the sonic ladder.
Once upgraded the Squeezebox™ Classic the overall presentation is cleaner, more open, with a marked reduction in digital artefacts such as glare and hardening. Detailing and dynamics are improved, the music gains substance and depth with low frequencies benefiting from increased weight with the highs sounding sweeter, more natural.
Squeezebox™ Classic (SB3) products can now be upgraded with the Audiocom Superclock 4. This modification can be installed as a stand-alone upgrade or in conjunction with our level-1 or level-2 modifications.
The factory clock fitted in the Squeezebox™ players is a ‘Pierce’ type using a 74HCU04 inverter chip. This type of oscillator is simple and easy to implement but also very noisy, jittery. With jitter minimized, low to mid frequencies gain substance, high frequencies are cleaner, image focus and dynamics are significantly improved.
There are numerous setup options with the Squeezebox™, the choice of using the integrated line-out or adding a separate DAC, using the switching power supply or adding a higher grade linear, etc. We have a range of modifications to suit individual setup and budget.
► SB3 /Classic Level-1 Digital Upgrade:
• Sanyo OS-CON SP for DC input bypass;
• Super-regulator 3 for 3.3V digital supply;
• Sanyo OS-CON SP regulation bypass;
• Bybee Slipstream Purifier for digital output.
► SB3 /Classic Level-2 Digital Upgrade:
• Sanyo OS-CON SP for DC input bypass;
• Bybee Slipstream Purifier for DC Input;
• Super-regulator 3 for 3.3V digital supply;
• Sanyo OS-CON SP regulation bypass;
• Bybee Slipstream Purifier for digital output;

Squeezebox™upgrades installed by The Bolder Cable Company
The Statement mod upgrades the parts and circuitry of the SB's internal power supplies. The mod also removes all the stock parts from the analog section. The signal path is now run direct from the internal DAC through very high quality coupling capacitors to new RCA jacks.The output level of the signal now has a max output of 1.1 V rms down from the 2 Vrms of the stock unit.
This top level of mod upgrades the output bypass capacitor to the V-Cap Teflon capacitor. All of the internal power supplies use Black Gate caps in their "Super E" configuration. Resonance dampening material is used in critical areas.
The output connectors are changed to WBT NextGen. A Bybee Purifier is used to reduce noise.
This is the mod to get if you want the simplest signal path. The modded SB3 can be run directly into a power amp. The volume can be controlled through the SB3's internal control. There will be no loss of sonic quality, In fact, most people with this mod report far improved sound quality running direct into an amp without a preamp getting in the way.
This mod improves upon the Enthusiast level and offers even clear more natural sound the highs are extended and very sweet. The low end is VERY tight.

Welborne Labs Squeezebox™ Power Supply Upgrade
The Logitech® Squeezebox™ has become a very popular streaming music player however it is packaged with a very wimpy and noisy switching power supply that inhibits its true potential.
Our upgrade design incorporates a tightly regulated linear power supply featuring low noise Schottky rectifier diodes, low noise, low drop-out voltage regulator chips, Ultra low impedance Nichicon capacitors and a high-current-low-noise-split-bobbin transformer (get it? it's designed for very low noise).
Our power supply measures less than 50 microvolts of ripple under full load resulting in very quiet operation with plenty of reserve current for good dynamics. Additional benefits are obtained with the use of a ceramic fuse, Vishay/Dale 1% metal film resistors, Wima polypropylene bypass cap, heavier gauge dc power cable and a detachable ac power cord.
The sonic results achieved include a blacker background with excellent low level resolution and detail, an expanded soundstage along with deeper and tighter bass. The Squeezebox™ sounds pretty good stock, but our power supply will raise the performance to the level you demand. We're confident you will hear the improvement!
The aluminum chassis measures just: 4.25"W(108mm) x 7"D(178mm) x1.8"H(46mm) and is available in red or black anodized finish. All versions accept detachable AC power cords however the cord is NOT included and must be purchased separately. We have Power Supply Upgrades for the Squeezebox Classic, Squeezebox 2 & 3, Duet and the new Touch.
Please specify below when ordering. Available factory assembled for $260.00 or kit for $205.00. The factory assembled version is warranted for a period of three years.

Logitech® Squeezebox™ Duet
Système musical réseau qui vous permet d'écouter et de contrôler votre musique numérique préférée dans chaque pièce.
Votre musique à votre façon
Avec un lecteur Logitech® Squeezebox™, tout dépend de vos envies. Vous préférez peut-être n'écouter que votre collection musicale personnelle. Ou alors vous êtes toujours à la recherche de nouveautés. Quels que soient vos goûts musicaux et votre style d'écoute, un lecteur Squeezebox™ vous offre une liste de lecture infinie.
Votre propre collection
Que votre bibliothèque contienne 100 ou 100 000 chansons, que vous graviez vos propres CD ou achetiez votre musique à partir de services comme iTunes®, Amazon® MP3 ou eMusic. Votre Squeezebox™ vous permet de parcourir, organiser ou écouter votre collection musicale numérique n'importe où dans votre maison.
Vous avez de la musique sur plus d'un ordinateur à votre domicile? Aucun problème. Votre Squeezebox™ peut tout trouver, que vos ordinateurs fonctionnent sous Windows®, Mac OS® X ou Linux. Vous bénéficiez même d'un accès instantané à la musique que vous stockez sur votre disque réseau NAS ou sur votre répertoire de musique MP3tunes.
Tout un monde de radios Internet
Le divertissement ne s'arrête pas à votre propre collection. Vous pouvez écouter tout un monde de divertissement provenant d'ici et d'ailleurs avec votre Squeezebox™. Des milliers de stations de radio Internet gratuites vous font profiter de tous les types de musique allant de la pop grand public à des sons trop éclectiques pour la bande FM. De la musique, des talkshows et des podcasts, vous pouvez tout écouter.
Récemment, la Squeezebox™ avait déjà changé fondamentalement la manière de consommer de la musique dans la maison mais la Squeezebox™ Duet va encore bien plus loin et propose un confort ultime pour peu que vous disposiez d’un réseau Wi-Fi chez vous.
Logitech® vient de lancer une nouvelle version de son lecteur musical en réseau, la Squeezebox™ Duet. Le principe de base est inchangé avec un lecteur connecté à toute chaîne par une classique connexion audio et branché sur le réseau domestique pour diffuser la musique qu’il puise sur le Web et sur les ordinateurs reliés.
Mais Logitech® a franchi une étape supplémentaire avec la Squeezebox™ Duet en déportant l’affichage et la réception sur la télécommande. Avec deux avantages principaux à la clef: la possibilité d’adresser plusieurs lecteurs répartis dans la maison et une commande bien plus agréable à distance. Nous verrons aussi qu’un troisième avantage qui paraît évident à la réflexion n’a pas été implémenté, du moins pour l’instant.
Si l’installation et la connexion n’ont rien de compliqué en soi, le système nécessite tout de même un certain nombre d’explications préalables qui d’ailleurs ne figurent pas dans la documentation fournie. À ce propos, si je ne suis pas pour le gaspillage du papier, le fait qu’aucune documentation complète ne soit fournie ni imprimée, ni sur CD est inadmissible.
Il faut donc commencer par la télécharger, tout comme le logiciel pour le PC. Ce n’est pas un problème en soi mais comme le guide fourni manque cruellement de détails sur l’installation et que la documentation n’est proposée qu’après avoir débuté la procédure en allant sur le site dédié, c’est franchement déroutant.
La Squeezebox™ Duet est livrée avec les accessoires suivants:
• Squeezebox™ Remote Control;
• Squeezebox™ Receiver;
• Charging cradle with power supply;
• Power supply for receiver;
• RCA to Jack cables;
• Rechargeable Li-ion battery pack;
• Quick-Start Guide;
• 2-year limited hardware warranty.
Un lecteur discret
Le lecteur fourni est simplement un petit boîtier noir très discret qui se place à côté de votre chaîne audio ou d’une paire d’enceintes amplifiées. Il s’y connecte par les traditionnelles prises cinch analogiques stéréo ou en numérique par l’optique et le coaxial.
Logitech Squeezebox Duet - Receiver.
Ensuite, il se relie au réseau par le Wi-Fi G, ce qui suppose que vous soyez équipé d’un routeur point d’accès idoine lui-même connecté au Web. Le lecteur est également doté d’une prise réseau Ethernet par laquelle il peut alternativement se relier au routeur en filaire.
L’alimentation se fait par un adaptateur secteur discret livré. Dépourvu d’interrupteur, le lecteur dispose en tout et pour tout d’une LED en façade qui change de couleur selon son état.
La télécommande fait tout
En fait tout se passe sur la télécommande, magnifique au demeurant, et dotée d’un large écran LCD couleur haute résolution d’une diagonale de 6 cm ou 2,4 pouces. Elle est fournie avec un socle avec adaptateur secteur dans lequel elle se glisse pour se recharger.
Logitech Squeezebox Duet - Télécommande bidirectionnelle.
Logitech Squeezebox Duet - Chargeur de la télécommande bidirectionnelle.
C’est cette télécommande qui va centraliser les informations directement depuis le Web ou un PC et pour cela, elle se connecte obligatoirement sans fil soit à votre routeur (point d’accès sans fil), soit en se servant du lecteur comme passerelle s’il n’y a pas de réseau sans fil.
En fait, et c’est ce que vous apprend la documentation non fournie, il y a trois cas de figure pour la configuration. Première possibilité, vous disposez d’un réseau domestique sans fil en Wi-Fi doté d’un routeur point d’accès ou d’une box opérateur Wi-Fi qui fait office de point d’accès.
Par ailleurs, le lecteur n’est pas à proximité du routeur et de la box. Dans ce cas, la télécommande et le lecteur vont se connecter en Wi-Fi au réseau. Autre situation, vous disposez du même équipement mais votre lecteur est à proximité du routeur ou de la box.
Dans ce cas, il est préférable de relier le lecteur au routeur en réseau filaire par un câble Ethernet ce qui le rendra indépendant des aléas de la transmission Wi-Fi. La télécommande en revanche reste connectée en Wi-Fi au réseau.
Enfin dernier cas, vous ne disposez pas d’un réseau Wi-Fi mais juste d’un routeur filaire relié à Internet. Alors le lecteur se connecte obligatoirement par un câble Ethernet au routeur et la télécommande en Wi-Fi sans fil au lecteur qui sert de passerelle, en sachant que la connexion sera moins bonne avec une portée moindre et un débit plus bas.
Dans tous les cas pour que l’achat d’un Squeezebox Duet ait un sens, il faut que vous soyez déjà équipé d’un réseau domestique avec un routeur.
Filaire Ethernet ou Wi-Fi?
Que le lecteur soit relié en filaire (Ethernet - câble RJ45 de classe 5 ou 6) au routeur ou en W-iFi, dans les deux cas, tout a parfaitement bien marché. Nous avons fait des essais de distance et les règles sont les mêmes que pour tout Wi-Fi G standard.
En dehors d’obstacles inhabituels comme un mur en treillis métal, la portée est d’au moins 20 mètres sans qu’il n’y ait de problème de réception et ce que ce soit entre le routeur et le lecteur ou entre ce dernier et la télécommande. Une maison ou un appartement de taille standard devraient donc être couverts.
La connexion au réseau sans fil se fait simplement en suivant les instructions en français à l’écran de la télécommande avec le cas échéant l’entrée du mot de passe de votre protection qui peut être de toute sorte, même WPA évolué.
La solution d'une connexion par câble RJ45 classe 5 ou 6 est cependant à préférer du fait qu'elle assure une transmission des données parfaitement fiable.
Se connecter
Avant de pouvoir trouver du contenu audio sur le Web, il faut créer un compte sur Internet auprès du Squeezenetwork. Et là déjà, cela se gâte un peu puisque tout se fait en anglais. Une fois cette opération effectuée, vous pourrez accéder aux radios Internet ainsi qu’à d’autres services musicaux, nous y reviendrons par la suite.
Pour accéder à la musique sur votre ou vos ordinateurs reliés au réseau domestique, il faut télécharger une application, le Squeeze Center. On peut trouver cette double installation un peu alambiquée et c’est mérité mais l’installation du logiciel se fait très simplement puisqu’il détecte automatiquement la Squeezebox™ Duet et scanne votre PC à la recherche de toute musique.
Et pour ceux comme moi qui détestent l’organisation Windows Media Player, il suffit d’indiquer le répertoire parent qui abrite toute votre musique. L’interface est Web et assez bien fichue mais en fait, vous n’aurez plus besoin d’y recourir par la suite. Tout ceci est compatible Vista sans soucis.
Vous voilà enfin prêt à utiliser le système. Tout va se faire par la télécommande et son grand écran très défini. Déjà, vous pourrez piloter votre lecteur où que vous soyez tant que vous êtes à portée Wi-Fi du routeur Le système de commande est un exemple de convivialité.
Les touches directes se limitent au volume et la lecture. Tout le reste passe par une molette rotative et une validation centrale plus quatre touches de navigation autour.
Ainsi pour lire de la musique contenue sur votre PC, il suffit d’aller dans votre collection musicale et de chercher par album, artiste, morceaux, etc. Ensuite, le cas échant la pochette de l’album et les morceaux s’affichent, vous n’avez plus qu’à lancer la lecture.
Tous les formats courants sont reconnus, y compris l’OGG Vorbis et le FLAC. Ceux qui ne le sont pas directement comme l’Apple Lossless sont transcodés à la volée par l’application PC. En revanche, pas de compatibilité avec les DRM des musiques protégées.
Mais, vous pouvez aussi aller chercher du contenu directement sur le Web. Il y a déjà une très large collection de radios avec plusieurs services comme Radio Time, Live 365, Radio IO et Shoutcast.
Le choix est donc très large et vous devriez trouver votre bonheur quels que soient vos goûts. Évidemment, toute radio peut être mémorisée en favoris pour la retrouver instantanément. Vous disposez même des services d’informations en continu comme ceux de la BBC qui s’affichent en texte à l’écran ainsi que l’accès aux podcasts.
Jusque là tout va bien. Malheureusement cela s’arrête là aussi car les services Web les plus intéressants ne sont toujours pas arrivés en France. Les radios à la demande qui vous proposent des sélections musicales en fonction de vos goûts comme Pandora ne sont pas disponibles dans l’Hexagone.
Pis encore, un coupon Last FM est fourni dans la boîte avec la mention deux points ouvrez les guillemets "Ne fonctionne pas en France"! Sic. Et le pire est à venir. L’exceptionnel service de musique à la demande Rhapsody, qui pour 10 euros par mois vous offre trois millions de morceaux en libre accès streaming, n’est pas accessible en Europe pour des histoires de droit.
Le seul service intéressant a priori est MP3 Tunes qui permet de mettre votre musique sur un serveur en ligne pour y accéder sans PC. Mais avec une connexion ADSL standard, cela prend des années si vous avez une collection conséquente, autant y accéder par le PC.
Tout ceci est donc assez frustrant. Pour plus de détails, relisez notre article sur la Squeezebox originale. En revanche, la qualité de restitution audio est excellente et ce quelle que soit la connexion utilisée.
Un confort optimal
Restent l’accès à la musique de vos PC et aux radios Internet en attendant que Logitech® trouve un jour un accord avec un service de musique à la demande dans l’hexagone (Dezeer depuis juin 2010). Et surtout, il y a l’exceptionnelle ergonomie de la télécommande.
C’est un plaisir de tous les instants que de se balader dans sa bibliothèque musicale ou de chercher une radio, et surtout de le faire sans se soucier de la proximité avec le lecteur. L’ergonomie n’est d’ailleurs pas sans rappeler celle de l’iPod, une référence donc.
Anecdote de traduction approximative amusante, l’aide à l’écran de la télécommande appelle la molette le bidule. En attendant, le bidule est diablement efficace pour chercher et l’aide l’est tout autant.
Le réel intérêt de se système par rapport à la Squeezebox originale et outre le confort accru, c’est de pouvoir piloter plusieurs lecteurs qui vous sont vendus en option pour la somme de 129 euros (décembre 2010).
Mais vous pourrez alors adresser chaque lecteur avec la même télécommande pour restituer la même musique ou une autre et ainsi vous créer un système multi-room vraiment fabuleux. Il est même possible de multiplier les télécommandes.
Conclusions
Avec la Squeezebox™ Duet, Logitech® a réussi le système de lecture musicale en réseau le plus sophistiqué qui soit avec il est vrai une ergonomie exceptionnelle à la clef, et un prix de 269 € en décembre 2010.
Depuis le 16 juin 2010, Deezer poursuit son développement sur le terrain de la mobilité et du multi-support en s’associant à nouveau avec Logitech®. Il est désormais possible de retrouver, à travers l’abonnement Deezer Premium (4.99 €/mois), toute l’offre Deezer sur toute la gamme Squeezebox™ de Logitech®.

Voici quelques informations très techniques sur les possibilités offertes par la nouvelle télécommande WiFi de l’ensemble Squeezebox Duet avec écran couleurs. Il semble donc que l’on puisse aller très loin en faisant contrôler à cette télécommande autre chose qu’une Squeezebox. Merci à ce lecteur fidèle de Multiroom.
Quelques précisions sur l’intérêt que revêt la télécommande de squeezbox Duet. Elle est équipée d’un Linux (2.6) et le kit de développement est complètement ouvert, il s’agit de Jive pour la partie motorisation et SDL pour la partie graphique. La couche de communication est WiFi et le protocole d’échange est hyper standard puisqu’il s’appuie sur JSON.
Cela signfie que tout un chacun, ayant envie de développer, peut désormais apporter sa contribution à l’interface, au moteur de traitement (a priori) de cette télécommande ainsi qu’aux bricoles échangées entre cette télécommande et un serveur (qui par défaut est la slimbox mais qui peut être tout autre chose, partant). Enfin, une innovation dans ce domaine : l’ouverture ! De quoi la personnaliser…

Logitech leveraged their ability to stream audio to customers with their acquisition of Slim Devices two years ago. The Squeezebox™ Duet enables users to stream their favorite audio content from their personal collection, online services (Pandora and Rhapsody) and thousands of Internet radio stations.
The system supports a wide variety of non-DRM content including compressed formats (MP3, AAC, Ogg Vorbis, MP2, MusePack, WMA) and uncompressed formats (AIFF, WAV, PCM). Play songs stored on your computer, tune in to thousands of Internet radio stations, or connect to online services such as Pandora® and Rhapsody®. On the downside, the Squeezebox™ Duet cannot play music stored on a NAS (Networked Access Server) where all of my music is stored.
Instead, the Squeezebox™ Duet must connect to a PC running SqueezeCenter software or to third party music storage companies such as MP3tunes.com music locker making it possible to listen to your personal music collection without turning on your computer.
Squeezebox™ Server
Squeezebox™ Server is the music server that runs on your computer and connects your Squeezebox™ players and controllers to your local music files, as well as allowing you to use third-party plug-ins (applications that extend the features and functions of your Squeezebox™).

If you’re planning to use your Squeezebox™ Duet only to listen to Internet radio and online music services, or if your music is stored in an MP3tunes music locker, you are not required to have a PC running this software. Currently, MP3tunes music locker storage space is limited to 2GB for free. Larger storage space is available for an additional fee. We tested the Squeezebox™ Duet running SqueezeCenter on our media server PC.
Handheld
The handheld controller that come with the Squeezebox™ Duet has a rechargeable Li-Ion battery and measures only 6-1/8" tall, 2" wide and 0.75" deep. The remote sits in a cradle that not only makes it easy to find, but also keeps the controller charged through the two contacts at the base. A beep can be heard when the remote docks to the base confirming a good connection with the charger.
The menu options from the home screen.
The buttons on the remote have a tactile feel and the rotating wheel around the center select button is a nice touch. Just below the navigation keys are the volume buttons and the forward/reverse and pause buttons. The 2.4-inch color LCD screen is easy to read and provides plenty of information about the artist, album, song, and track.
Browsing into the my Music menu item.
The Now Playing view; album art, album name, track number, song name,
song progress, time, battery life, Wi-Fi connection, play/pause status,
and repeat on/off...a lot of information at a glance!
Album cover art is also displayed. At the base of the display, the handheld has indicators for playback mode, signal strength, battery level, and time. Once the handheld goes into standby mode, the display becomes a real-time clock, which can be a useful feature.
Base Unit
The base unit is small measuring only 6-1/4" wide, 4-1/4" deep, and 1-1/8" tall. There is not much to see on the front panel except for the Home button located in the center This button is used to reset the unit and provides visual feedback to the user. A blinking red indicator lets the user know the unit is resetting. Once the color turns white, the unit is connected to the network.
Interfaces
The rear panel of the Squeezebox receiver has a wired Ethernet interface. The unit also supports 802.11g Wi-Fi for those with wireless networks. Both coaxial and optical (Toslink) digital connections are provided along with analog stereo outputs.
The receiver immediately recognized our SSID on our wireless network and we were prompted to enter our password for access. We tested both the wired and wireless connections to this unit. We also connected the analog audio as well as the Toslink output connected to our Denon AVR-5308CI A/V receiver. The universal power adapter can run from 100-240VAC, 50-60Hz making it compatible around the world.
Performance
The Squeezebox™ Duet produces excellent sound quality thanks to the 24-bit DAC and sophisticated audio rendering technology. We maximized our bandwidth by using a wired Ethernet connection to the base receiver. However, it is just as easy to use a wireless link if this is more convenient.
We did experience some lag time between button presses when using the wireless connection, but this may be completely dependent on the type of wireless hardware you have installed in your home or office.
Once our system was setup, we were able to stream our music content seamlessly to our audio system. I particularly like the controller and the display, which provides nice feedback to the user. The lightweight and ergonomic design makes listening to music or Internet radio stations simple and easy.
I was somewhat surprised just how good the lower bandwidth radio station sounded on this system. In many cases the audio was running at a paltry 20-30 kbps, yet sounded much better than other low bitrate recordings I have heard. Both analog and digital interface sounded quite good.
Conclusion
The Logitech® Squeezebox™ Duet ($359.99) is a great way to get music streaming in your rooms with the convenience of a user friendly handheld remote. The system is easy to setup and provides excellent sound quality from good source material.
Internet radio and other lower bandwidth sources will have slightly less audio quality, but can only be discerned on higher quality audio systems. The style, build quality, and features offered with the Squeezebox™ Duet certainly justifies the price. Few products are available with the convenience offered with the Squeezebox™ Duet.
Most of the systems we have seen are significantly more expensive such as the Sonos Music System we reviewed last year. If you are looking for a way to distribute music or Internet radio in your listening space and want the convenience of a remote with a cool display, you owe it to yourself to check out this product.

Transformez votre P.C. en Squeezebox !!!
Depuis cet été 2011, il est possible de transformer son P.C. en Squeezebox, en installant sur celui-ci le programme SqueezePlay de Logitech (version Beta au 11.08.2011), qui offre après l'avoir installé, exactement le même menu que la télécommande de la Duet, ainsi que la possibilité de contrôler les autres Squeezebox installlées dans votre maison.
► Télécharger SqueezePlay sous Windows, Mac, ou Linux ici
Ici, c'est la Version 7.6 qui a été sélectionnée, sur la page suivante, choisir en fonction de son système d'exploitation la version de SqueezePlay et de Squeezebox Sever (au cas où vous auriez omis une mise à jour).
SqueezePlay est en version Bêta, il est important de télécharger régulièrement la dernière version. Avant d'installer une nouvelle version, il est conseillé de désinstaller l'ancienne version en supprimant le dossier SqueezePlay dans Program Files.
A toutes fins utiles vérifier à partir de la commande de chaque Duet que l'option "Activer la lecture (BETA)" est cochée, pour ce faire sélectionner "Paramètres", "Avancé", "Fonctions bêta", "Lecture audio".
Ouvrir Squeezebox Sever afin de vérifier que SqueezePlay a bien été enregistré dans la liste de vos platines (ici, SqueezePlay diffuse un programme musical simultanément avec les platines Duet chambre, Slim Bureau, et Duet salon, les autres platines n'étant pas sous tension):
Une réserve, quelques soient les performances du chipset audio de votre carte mère et/ou de votre carte audio - infos, la qualité de retranscription sera dépendante des haut-parleurs équipant votre P.C.... oublié la musicalité de votre ampli, la vigueur des woofers et la richesse du médium de vos enceintes de salon, mais faite l'essai d'une solution à la fois complète et très simple, tant dans sa mise en œuvre que dans son utilisation!
Il demeure néanmoin un intérêt économique à posséder des Squeezebox "physiques", celui du coût de plusieurs P.C.
Streamin By Bitrate
Bitrate est un terme anglais que l'on peut traduire en français par "taux d'échantillonnage fixe" qui décrit la façon dont la piste audio est encodée.
En effet, plus on compresse le signal et moins la qualité audio est bonne, sachant qu'un un signal encodé en MP3 avec un bitrate de 64 kbits/s a une bande passante de 11 kHz. Ceci signifie que toutes les fréquences situées entre 11 et 20 kHz sont supprimées!
Par ailleurs, pour obtenir un tel taux de compression, outre la suppression des fréquences, on a également transformé les HF en signal mono au lieu de leur conserver leur caractère stéréo.
| Bitrate | Qualité | Compression |
| Master | Supérieure au CD audio | Aucune |
| 320 kbps MP3 | Inférieure au CD audio | |
| 256 kbps MP3 | Inférieure au CD audio | 1:4 |
| 192 kbits/s MP3 | Inférieure au CD audio | 1:7 ou moins |
| 128 kbits/s MP3 | Très inférieure au CD audio | 1:11 |
| 96 kbits/s MP3 | Supportable | 1:15 |
| 64 kbits/s MP3 | Limite | 1:22 |

Quelques stations de radio diffusent en 320 kbps. Avec la Duet il est possible de les sélectionner comme suit :
► Onglet "Personnalisation du Menu principal"
• Valider "SHOUTcast (le carré passe au bleu)
► Menu principal
• Sélectionner "SHOUTcast"
• Sélectionner "By Bitrate"

Upgrade Squeezebox™ Duet
Squeezebox™Duet upgrades installed by The Bolder Cable
The Logitech Duet is the newest network music player to come from the folks who gave us the SqueezeBox.
The Bolder Cable Company - Duet full mod.
Here is a quote from a recent review on the Website "Computer Audiophile" :
"The stock Duet is a convenient niche product with decent mid-fi sound. The Bolder Cable modifications take that sound up a notch or two by squeezing every ounce of performance possible from the device. Simply put, if you like the Duet now you'll like it even more with the Bolder mods. In fact the Duet with Bolder Cable Company modifications may rival the more expensive Logitech Transporter."
We have come up with some changes to the internal parts that we feel improve the sound.
This mod replaces the reservoir power supply capacitor with one of higher quality. The output coupling capacitors are replaced by a blend of BlackGate and Sonicap Gen2 caps. Upgrades are available using Sonicap Platinum or V-caps. The output connectors are replaced with Cardas RCA with the option for WBT NextGen RCAs.
We also remove everything in the digital signal path and run a 75 ohm coax direct to a WBT NextGen RCA.
We have improved the mods based on our work on the RE-BOX project.
We are now improving the power supplies for the clock and DAC chip circuits.
The mods will improve the dynamics, lower background "noise" levels and extend both the low and high frequencies with more detail.
We do suggest you also replace the stock switching power supply with a linear power supply.
Squeezebox™Duet upgrades installed by Leo
The next stage was some internal mods, the first round is going to be basic stuff easy for most to try if they wish, nothing new here Heres the standard Duet pcb. First thing was to replace the filter cap on the input DC socket, the standard one is a general purpose SMD type which is probably next to useless especially if using the external SMPS, I replaced it with a Oscon , any low ESR should be ok here, stability using low ESR in this position was fine.

Avis d'utilisateurs de la Squeezebox™ Duet
► Vous indiquez dans ce test qu'il n'est pas possible d'utiliser la télécommande (Squeezebox™ Controller) comme "baladeur MP3". Il convient de rétablir la vérité: depuis la version 7.3 de SqueezeCenter (devenu Squeezebox Server), il est tout à fait possible d'utiliser la télécommande pour écouter de la musique avec un casque.
Signé: un utilisateur de Squeezebox™ comblé...
► Ce produit était fait pour moi! il me permet de stocker toute ma musique et de l'écouter sans allumer mon ordi. Toute la musique du monde m'y est accessible, je peux même regarder mon Facebook sans utiliser mon portable.
► Il est important de bien paramétrer son compte afin d'utiliser au maximum tous les services proposés. La télécommande s'utilise comme un "Ipod" et est très simple d'utilisation. Ce produit est révolutionnaire vous ne serait pas déçu...
► Après quelques jours d'utilisation, je suis conquis par:
- la qualité sonore (un gros "tampon" fait qu'il n'y a pas de coupures (cf. le
débit Wi-Fi de votre réseau domestique ou le débit Internet du site auquel
vous êtes connecté);
- la bonne convivialité (8/10) du menu, paramétrable, de la télécommande;
- la réponse exacte à mes besoins.
► Un très bon produit qui permet d'approcher la Hi-Fi du future. L'installation est relativement aisé à condition de trouver le mode d'emploi sur Internet grâce à la bienveillance des internautes qui m'ont donné l'adresse Web , ce qui est inadmissible pour une marque tel que Logitech® .
La qualité est excellente à partir d'un serveur Nas notament le synology 207 + ou nouvelle génération surtout si la musique a été enregistrée soit en FLAC soit en AIF, le tout reproduit sur des quad esl 63.La Squeezbox à une sortie un peu faible comparée a une sortie de DAT ou minidisc bien que branchée directement en optique sur le CD numérique Quad. La qualité musicale est au rendez-vous et il est très difficile de faire une différence entre un cd et le système Logitech® . j'ai enlevé une étoile à cause du mode d'emploi.
► Je ne vais pas en faire des tartines ...
Connecté à un NAS Synology DS209J en Wi-Fi sur mon réseau (Linksys WRT54G) la squeezebox est branchée sur mon Home cinéma à 1 étage. Radios internet, Deezer, musique du NAS c'est que du bonheur! Le forum Synology apporte toutes les infos pour faire vos branchements de la sqeezebox en mode NAS (sinon il faut garder le PC allumé pour profiter de ses morceaux de musique). Bref c'est 5 étoiles - mais attention il faut quand même connaître un minimum l'informatique pour réaliser ce type de connexion.
► Je dois avouer que depuis quelques années, je "faisais avec" ma chaîne Wi-Fi, obligée de naviguer dans des répertoires informatiques quasi en aveugle, au moyen des boutons d'une télécommande siglée "multimédia" et non "informatique". Mais bon, je lui pardonnais, au moins je pouvais écouter mes fichiers MP3 à la fois depuis un PC, mais aussi sur la chaîne qui dessert musicalement le salon et la cuisine. Et tout le monde le sait, les MP3, c'est quand même génial, surtout quand on a des enfants qui n'ont pas compris des principes de base, genre:
- Les CDs, c'est joli, on se voit dedans, mais ça fonctionne beaucoup moins
bien après qu'on ait joué avec.
- Et encore moins bien quand on a marché dessus. Même si on fait moins de
15 kilos.
- Et puis c'est pas utile d'essayer d'en mettre le plus possible en même
temps dans la chaîne.
- Surtout si on les introduit sans ouvrir les plateaux de chargement.
- D'ailleurs, tous les sortir des boites pour faire des piles par couleur, ce
n'était vraiment pas une bonne idée.
Et puis cette chaîne, finalement, à force de m'arracher les cheveux en naviguant dessus à grand peine (je ne suis pas non plus d'une patience légendaire, c'est vrai), j'avais fini par arrêter de m'en servir. Au point que la chaîne Hi-Fi SONY de ma jeunesse avait récemment réussi à retrouver subrepticement le chemin du salon. J'avais même exhumé mes CDs du coffre dans lequel je les avais rangés, hors d'atteinte de mes enfants. A moi la musique facile, j'introduis un CD, bouton PLAY, et hop!
Mais l'Homme ne l'entendait pas de cette oreille, et j'ai vu apparaître sur ma chaîne une petite boite noire, accompagnée de sa télécommande avec écran LCD. Et c'est tout bonnement génial!
Le p'tit plus, c'est que la télécommande (c'est du 802.11b/g, donc pas besoin de la pointer ou même d'être en vue du boîtier!) affiche le titre en cours, le temps restant, la pochette associée. Le boîtier se branche sur l'entrée AUX de n'importe quel appareil mutimédia pour profiter de ses enceintes, et se connecte en Wi-Fi ou en filaire Ethernet pour aller piocher dans votre stock de fichiers. Sans serveur, ou sans ordinateur d'allumé, il reste toujours la solution de se connecter à de la musique en ligne...
Je l'avoue, les radios Internet m'ont aussi bluffées, surtout que par chez nous, le réglage de la réception d'une radio est très aléatoire. Alors que les radios Internet, globalement, qu'il souffle, qu'il vente, qu'il pleuve ou que les petiots aient déplacé l'antenne pour la mille et unième fois, elles s'en fichent.
J'adore le progrés...

• Que faire si Squeezebox Server ne s'ouvre pas en même temps que mon P.C.?
Par défaut, Squeezebox Server est installé pour être exécuté en tant qu'application, mais il faut parfois le configurer pour être exécuté en tant que service. Pour l'exécuter en tant que service, procédez comme suit: muni de votre "Nom d'utilisateur" et de votre "Mot de passe" à Squeezebox Server, suivre les indications fournies par l'Assistance de LOGITECH en fonction du système d'exploitation de votre P.C.
► Assistance LOGITECH ici
• Je me demande tout de même à quoi sert la prise casque au sommet de la télécommande, car elle n'est pas fonctionnelle?
Cette prise doit être activée dans les paramètres avancés. Sur le SBC: paramètres>Avancé>Lecture audio>Activer la lecture (BETA). Ensuite dans la liste des platines disponibles, apparaît "Controller". En le sélectionnant, il joue la musique (casque ou mini haut-parleur intégré).
• Comment fait-on pour synchroniser deux Squeezebox™? Est-ce une fonction spécifique ou faut-il tout simplement brancher les deux boites et les placer sur la même radio par exemple?
Cela se fait sur l'application SlimServer: on choisi pour chaque Squeezebox™ si elle joue toute seule ou si elle est synchronisée (et avec quelle autre Squeezebox™ si on en a plus que 2). On peut également sélectionner la synchronisation ou non du volume sonore entre 2 ou plusieurs SB.
• Comment puis-je utiliser plusieurs dossiers ou disques comme sources de musique dans SqueezeCenter?
Pour utiliser plusieurs dossiers et/ou disques comme dossier de musique, procédez comme suit:
► Windows:
1° Créez des raccourcis vers vos autres dossiers de musique.
2° Placez les raccourcis dans le dossier défini dans le SqueezeCenter comme
votre source de musique. Le contenu de ces autres dossiers fera alors
partie de votre collection musicale.
► Macintosh:
1° Créez des alias vers vos autres dossiers de musique.
2° Placez les alias dans le dossier défini dans le SqueezeCenter comme votre
source de musique. Le contenu de ces autres dossiers fera alors
partie de votre collection musicale.
• J'ai acheté une SB Duet l'année dernière que j'ai branché sur mon réseau local en sortie de la Freebox (Ethernet). Après quelques manipulations, j'ai réussi à la faire fonctionner avec le Controller et tout marchait correctement. J'ai acheté quelques temps après (au mois de mai dernier) un Squeezebox Receiver que j'ai branché (toujours en filaire à la sortie de ma box) sur mon réseau local. Je l'ai aussi configuré avec mon Controller sans problème et j'arrivais bien à accéder dans le menu du Controller à la sélection de la platine pour choisir lequel contrôler.
Sur ce j'ai déménagé. J'ai donc essayé de tout réinstaller et c'est là que cela se complique.
J'ai installé la dernière version de Squeezebox Server v7.4.1. J'ai branché ma première platine (Squeezebox Receiver) sur le réseau (toujours en filaire) et après une réinitialisation des paramêtres usine, j'ai pu connecter mon Receiver. J'ai installé ensuite le second Receiver sans succès. J'ai donc éteint (débranché) le premier Squeezebox Receiver. J'ai utilisé le Controller pour lancer le second Receiver en réinitialisant les paramètres usine et j'ai donc réussi à controler le second receiver. J'ai rebranché le premier Receiver et là, le menu de sélection de la platine n'apparaît pas sur le controller donc impossible de faire marcher les deux en même temps!
Avez-vous une idée?
L'intégration d'un système de sonorisation "mutiroom" composé de Squeezebox™ Receiver reliés à un réseau Ethernet (câble RJ45 de cat 5 ou 6), suppose le pré-requit suivant:
chaque nouvelle zone créée doit être "couverte" par la liaison Wi-Fi préexistante entre une Squeezebox™ Receiver déjà relié par Ethernet à un routeur ou à une box et paramétrée à l'aide de la Squeezebox™ Controller.
Un dessin vaut parfois mieux qu'un long discours:
Pour vérifier si la pièce dans laquelle vous souhaitez installer un nouveau Squeezebox™ Receiver est "couverte" par le signal du Squeezebox™ Receiver déjà installé, il suffit de vérifier la puissance du signal qui est indiqué par le pictogramme situé en bas à droite de l'écran de la Squeezebox™ Controller:
Nouvelle installation possible:
Installation impossible:
Dans l'affirmative, procéder à la configuration du Squeezebox Receveir comme suit:
1. Sur l'écran d'accueil du Squeezebox™ Controler, sélectionnez "Sélectionner une platine". une liste de tous les Squeezebox de votre réseau s'affiche, comprenant notamment votre Squeezebox™ Receiver qui n'étant pas encore configurée et indiquée comme suit: ex. Squeezebox B5973E (le code correspondant aux six derniers caractères de l'adresse MAC).
2. Sélectionnez votre nouveau Squeezebox™ Receiver et appuyez sur le bouton central du Squeezebox™ Controler pour commencer la configuration. Le bouton central situé sur la façade avant du boîtier du Squeezebox™ Controler change de couleur pour indiquer qu'il est en cours de configuration pour votre réseau.
3. Une fois le récepteur connecté au réseau, vous êtes invité à sélectionner une source de musique. Outre le Squeezenetwork, une seule source de musique locale doit être répertoriée. Sélectionnez votre source de musique préférée et appuyez une nouvelle fois sur le bouton central.
4. Lorsque le bouton situé en façade avant du boîtier du Squeezebox™ Receveir devient blanc, cela indique que votre Squeezebox™ Receveir est configuré et prêt à être utilisé.
5. Enfin, pour faciliter la sélection et le contrôle de votre nouveau Squeezebox™ Receveir, il vous faut lui attribuer un nom descriptif, comme "chambre", "salon", etc. (menu Paramètres), et une couleur d'arrière-plan d'écran différente.
• Après une mise à jour du micrologiciel de ma Squeezebox™ Duet, les icônes des stations de radio ont disparues (sélections Internet, Local, Monde, etc). Comment fait-on pour reprogrammer cette fonction?
A partir de la télécommande, ouvrir: Paramètres, Avancé, Applet Installer, Réinstaller après la mise à jour du micrologiciel, et valider cette commande. Eteindre et rallumer votre télécommande pour finaliser cette réinstallation.

DAC
A l'heure de la convergence numérique, bon nombre d'entre nous disposent d'une bibliothèque musicale conséquente. Plus pratique que les CD, vous disposez de milliers d'heures de musique sur votre ordinateur. Comment substituer la sortie son (souvent la sortie casque) de votre ordinateur pour obtenir un son qualité Hi-Fi ? L'entrée USB des DAC Audio est parfaitement calibrée pour cela. Elle permet de récupérer le son diffusé par votre ordinateur, de le transformer en signal audio analogique pour que votre chaîne Hi-Fi puisse en restituer la musique.
Musical Fidelity M1-DAC
Principe de la conversion N/A
Les meilleures sources numériques ne seront jamais parfaites sans un bon convertisseur audio : le DAC (Digital-to-Analog Convertor). Ce petit boîtier permet de supplanter la carte son de l'ordinateur pour exploiter vos fichiers numériques (MP3, FLAC, AAC) directement sur votre chaîne Hi-Fi. Les signaux numériques (binaires : 1 ou 0) sont convertis en signaux analogiques (nombre infini d'états). Les DAC Audio représentent la meilleure solution pour profiter de la bibliothèque musicale numérique de son ordinateur avec une haute qualité de traitement du signal musical.
Fréquence d'échantillonnage, résolution et types de convertisseurs
Les convertisseurs des DAC Audio disposent d'une fréquence d'échantillonnage et d'une résolution spécifiques. Plus celles-ci sont élevées, plus la qualité de restitution est bonne. Pour être performant, un convertisseur doit proposer au minimum un débit natif de 48 kHz à 16 bits. Pour répondre à des critères audiophiles, les convertisseurs haut de gamme possèdent des débits natifs identiques à ceux utilisés dans les plus grands studios d'enregistrement.
Un taux d'échantillonnage de 192 kHz à 24 bits conviendra parfaitement aux utilisateurs les plus exigeants. Le signal reste ample, et ne subit aucune perte qualitative. Certains convertisseurs bénéficient d'une solide réputation (Asahi Kasei, Burr-Brown, Wolfson…), et s'imposent comme des valeurs sûres.
Le taux de distorsion harmonique (ou distorsion harmonique totale)
Le taux de distorsion harmonique représente la variation d'un signal par rapport à son état originel. En d'autres termes, il incarne la quantité de déformation que subit un signal ou un courant lorsqu'il traverse un circuit de bout en bout. Plus ce taux est faible, plus le son obtenu est limpide. Un taux de distorsion harmonique élevé peut nuire à la transparence du signal, et aboutit à une résolution sonore imprécise.
Généralement, on considère qu'un taux inférieur à 0,05 % est suffisant pour restituer un signal propre et détaillé. Les convertisseurs les plus performants affichent des distorsions extrêmement faibles, qui aboutissent à des taux de l'ordre de 0,002 %, voir moins dans certains cas.
La bande passante
La bande passante d'un appareil définit la plage de fréquences qu'il peut reproduire. Elle s'exprime avec une tolérance, généralement de 0 à -3 dB.
Pour être considéré comme Hi-Fi, un appareil doit avoir une bande passante de 20 Hz à 20 kHz. L'oreille humaine entend les sons d'un bon niveau entre 25 Hz et 16 KHz. Cependant, les infra-sons sont perceptibles (par le crâne et la cage thoracique) jusqu'à 14 Hz. Il est dangereux d'émettre des infra-sons en dessous de 15 Hz, car cela peut provoquer des nausées et des troubles cardiaques. En étendant la bande passante au delà des fréquences audibles dans les aigus, jusqu'à 40 kHz, on garantit une meilleure précision temporelle des transitoires à laquelle l'oreille est très sensible.

In electronic, a digital-to-analog converter (DAC or D-to-A) is a device that converts a digital (usually binary) code to an analog signal (curent voltage, or electric charge). An analog-to-digital converter (ADC) performs the reverse operation.
Naim Audio DAC
Most modern audio signals are stored in digital form (for example MP3 and CDs) and in order to be heard through speakers they must be converted into an analog signal. DACs are therefore found in CD players, digital music players, and PC sound cards.
Specialist standalone DACs can also be found in high-end hi-fi systems. These normally take the digital output of a compatible CD player (only some CD players output a digital signal in addition to analog) or dedicated transport and convert the signal into an analog line-level output that can then be fed into an amplifier to drive speakers.
Similar digital-to-analog converters can be found in digital speakers such as USB speakers, and in sound card.
