Ecosystems And Switching Costs

When you reach a certain level in hi-fi or, as it is the case in particular with multi room systems, you are bound by a high level of inter equipment compatibility, your investment is certain to be substantial. This is not really new. What is new, however, is a coupling with so-called digital ecosystems that is so tight that it very quickly becomes a problem.

Let’s for the sake of argument take a house with 5 rooms, or more in line with the zone-term, areas where you listen to music. If some of these areas conjoin or overlap, you need devices in those areas to be in perfect synch. This de facto means that they need to be of the same brand and model family. In areas further from each other, where sound is not likely to spill across, this is less important but still we have come to enjoy a certain level of remoteness; the ability to turn off the bedroom music while cooking in the kitchen. This does not require the same level of compatibility but it does require the devices to abide by the same protocols which pretty much means either the same brand or DLNA conformance. Very few audio systems are strictly DLNA. Most have features that are not specified in the standard or features that the vendor feel should operate differently and are distanced from existing standards.

There are two levels of ecosystems at play here. First there are the compatibility matrix formed by the devices themselves. Very few devices can operate optimally in a mixed environment. A Bluesound cannot tell a Marantz amplifier to power on or switch input, just like a Technics amplifier cannot tell a Sonos system to pause a queue or switch off the Play:5 in the bedroom. The devices are blissfully unaware of each other and as thick as a Jethro Tull record. Surely this is not a catastrophe but it certainly is inconvenient. This means that, out of convenience, we tend to bind ourselves to one ecosystem and by that put our proverbial eggs in one basket. The day Simple Audio was shut down they left their community with entire sound systems starting a death roll. And the thing is that the eggs in this modern basket are much more fragile than, say, a turntable. When the ecosystem dies, the product effectively degrades and ultimately turns to dust. If our 5 rooms had 5 different brands of devices and one brand kicks the bucket or removes an indispensable feature, you can remove that one device at a reasonable loss instead of having to replace the entire system at a considerable cost.

Another ecosystem domain to reckon with these days is the controller operating system. Consider again our fantasy system. Let’s equip our 5 rooms with the same brand of audio streamer and sprinkle in a few extras; some amps and a TV. The amplifier and TV run DLNA for which there are an abundance of more or less reliable apps for iOS, Android, Mac and Windows. The streamers have their own app, which is not available for one of the phone OSes and is incredibly slow on another, excluding two controller types. Unfortunately it is one one of these excluded phones that we find the best DLNA client. Suddenly we find ourselves using two different controllers plus an abundance of old fashioned remote controls. Then one day the OS on our preferred controller device gets a change in conditions preventing the DLNA app from running. The conflicts are legio. I am not mentioning any names. Suffice it to say that this is not entirely grabbed from thin air.

Both ecosystems have a very short life span. It is really quite incredible that nobody protests. I can understand that companies producing equipment are reluctant, unilaterally making their devices compatible with the competition but that doesn’t discount the fact that consumers are the ones carrying the loss here. And to make matters worse, a whole new ecosystem is on its way into the game. Home automation. Very few hi-fi devices allow themselves to be operated from home automation systems. Most that do are only working due to tenacious communities dissecting the protocols used. Not because companies divulge the information freely or comply with available standards. Logitech, or more accurately Slim Devices, tried when they open sourced their Squeezebox software. An open and active ecosystem disregarding the original devices left more or less in a limbo state without software updates.

As with the ability to remotely control devices from afar, we have come to enjoy the pervasive experience audio in every room gives us. The days of yore where we had a stereo in the living room and a transistor radio in the kitchen are long gone. The demand in quality in ambient sound has become increased for most music consumers, while strangely the opposite is true for the central stereo. The main device has become less important. For a great many people even less capable than household stereos were 25 years ago. More people have relatively good ambient sound while very few have barely adequate detail listening devices. High-end audio is probably on the same level as always, and equally frowned upon. But that is a topic for another article.

Naim Mu-So In The Lottery

Naim Mu-SoNaim have put a Naim Mu-So up for draws among customers who purchase a Hi-resolution digital album from their music shop. The Mu-So is Naim’s take on a wireless, monolithic speaker to compete with products such as B&W Zeppelin. Inline with Naim’s usual graphic style, the Mu-So has a visual punch unlike most other products in its genre. It streams everything up to 24-bit/192kHz Flac on a wired connection and plays it back at 75W per channel. Unusual among its peers it supports multi-room streaming with more Mu-Sos connected and is controlled by either an iOS or Android device or via the [equally] unusually rudimentary remote that comes with the package.

Squeezebox vs Sonos vs Simpleaudio

Multiroom streamers, depending on multiroom definition, are few and far between. One thing is the ability to stream music from one central location and play it in more than one room, another is to actually play in sync if playing the same track in more than one location. Following the latter definition seriously narrows the field of contestants, leaving only Logitech Squeezebox and Sonos, at least within our financial limits. Scottish Simpleaudio does not yet have audio synchronisation but is promised to get it. But how do they compare? They all have their little quirks and shortcomings. Do these matter or are they basically just three flavors of the same thing?

I will refrain from trying to put words on subjective listening impressions; sound stages and vibrant timbres and whatnot. It is bound to fail not having a common reference. Sound quality is either god or bad, perhaps with an added adverb if quality is really good or really bad. All from the point of view of standard hifi. Not high-end audiophile extravaganza nor the iPod dock in your kid’s room. We want good sound but don’t get nerdy about it. Certainly not in determining differences in oxidization levels of copper in cables affecting capacitance or any other such controversy.

Logitech Squeezebox

SqueezeboxtouchThe Squeezebox family began as a simple media server in 2000 and today spans from the audiophile Transporter to self-contained semi-portables Boom and Radio. Central to Squeezebox is a server which collates music libraries and serves them on the network, converting files on the fly if necessary; transcoding. This server software is not absolutely necessary but required to get the fullest from the media players. The software is open source and there is a small but highly enthusiastic community surrounding it. Even the player software is open source, letting you turn any old Linux or Windows PC into a remote-controllable media player fully equal to any other Squeezebox player on our network. Incidentally; after Logitech bought Ultimate Ears, the Squeezebox products are now rebranded UE Squeezebox.

Our setup consists of Duets connected to regular hifi systems in living room and study, and a Boom for the library, software players covering the rest. Remote controls is a combination of Duets, software players, web pages and apps on Android and iPod. And talking of the latter; the iPeng app we use there is a fully functional media player itself [at an extra small cost].
All Squeezeboxes can be connected wirelessly or via ethernet. This is where stability comes into play. The wireless receiver in the Squeezeboxes appears to be rather intolerant, causing them to drop out on occasion or losing network connectivity altogether. This never happens when wired. But wiring a portable player is rather daft. When wiring is possible, however, it is definitely the way to go.

The Boom comes with built-in stereo speakers and a control panel nicely centered between them with a big, friendly knob and a miniscule remote with a magnet on it, letting it stick ever so neatly onto the top of the player [or indeed on your fridge, if you need it to]. It does, however, require a constant power supply. The Radio can be equipped with an optional battery making it truly portable. This has only one speaker but instead boasts a nice color display and can be easily set up as a clock radio in the bedroom with snooze button and all. On a note aside, the server software can be set up to transcode files per player. So to save on network bandwidth and reduce the risk of drop-outs, you can have the server transmit MP3s or some other compressed format, e.g. Ogg Vorbis, to Boom or Radio, and even set the level of compression per device.
The Transporter, the Touch and the Duet are all unamplified players. They must be attached to a hifi system via either a line-out or digitally via a separate DAC or connected to a digital input on an amplifier that has its own DAC. The difference between the Transporter and the other two players is primarily in the use of high grade components in the Transporter and balanced analogue connections. The DAC in the Transporter can cleverly be used for other digital devices as well, turning it into a DAC itself.

The Duet comes with a special remote control that itself can be used as a player, hence the name. Quite clever but not exactly mindboggingly useful. As a remote, however, the controller is rather good. It bears some resemblance with the now discontinued CR100 from Sonos, with touch-wheel and color display, albeit in a slightly more compact form for one-hand operation. The controller communicates wirelessly and can control not just the Duet but also other players on the network – also the software players.

Both Boom and Radio sound nice but certainly nothing more. Neither is capable of being more than what they are, a clever transistor radio, nor do they pretend to be. The Duet, however, is outstanding. The internal DAC is not very impressive but using an external DAC, the tiny box shines, capable of playing 24bit/48KHz files without transcoding. The Transporter can play 24bit/192KHz and the Touch 24bit/96KHz. My advice is to use a wired connection for all three when feeding them high definition files. The files can be rather hefty and require high bandwidth.
The server software that drives Squeezebox, is its Achilles’ heel – and its strength. It is not simple to set up and can be a nightmare to move to another server once it is installed, should that be needed [at least if you want to keep your settings intact]. Once installed, however, it can do magic. It serves music and transcodes as needed, all without hiccups. Sprinkled with a few plugins it can then be set up to filter music to keep Christmas songs in December and Neofolk off the Heavy Metal playlists but keep it on the Folk list. The Boom and Radio both have programmable preset buttons that we have programmed for a handful of favorite genres. Button one plays Rock, two plays Electronica etc. Search is active across all meta data and blindingly fast even with our massive music library. We use filters mostly to keep things apart that semantically belong together but for any number of reasons must be kept apart nonetheless. Sounds spooky but consider the Christmas songs for a second. Nat King Cole and King Diamond both have Christmas songs and they are tagged as such. Their names are even slightly alike. But they are also tagged with other characteristics, such as croon (not King Diamond, I might add), jazz, easy listening, heavy metal, Danish and cover to name the predominant ones. The only shared genres are Christmas and male vocal. The server can be set up to filter out certain tags; in December we allow Christmas songs, so if I select heavy metal in December, I may just hear King Diamond sing No Presents for Christmas. If I choose to play anything Christmas, chances are I might hear Nat King Cole roasting chestnuts immediately after the former. Perhaps not completely unheard of; the opposite situation might be, though. Another common scenario is audiobooks. Everything tagged with speech is filtered out unless specifically chosen. That means that when randomly playing songs from any genre, we don’t suddenly get a 20 minute recital of The Emperor’s New Clothes between Kaki King and Andy McKee.

One interesting feature on Squeezebox is manual network sync adjustments. Normally the players sync automatically but if you want to, you can change lag and delay per device. One situation where this can be really useful, is if you have two zones so far apart that sonic delay becomes annoying [rather than network latency] and one of these zones always plays louder than the other. Then you can tweak the delay so that when heard close to the low zone, the loud zone is in sync, while the low zones is drowned by the loud zone when heard from the other end. Difficult to explain but extremely practical for us. It can also be used to counter any lag in an external DAC, should that be necessary.


ConnectAngle_LargeSonos entered the playing ground in 2005 and from the beginning showed excellence in one point in particular: Simplicity – pure and simple. Everything that can be done automatically is kept away from the user. The players recognise each other on the network and configuration is extremely simple. There are a few options that could have used a tooltip of explanation but they are few and really, if you don’t know what they mean, chances are you don’t need them. If you need them, you probably know what to look for. This is something Sonos have always been good at and keep getting better at. This, however, means you can’t tweak Sonos. Everything works as they have set it out to. Special requirements – buy something else or live without them.

Our replacement system is one of 5 players. Two stationary and three portables. The stationary players come in two flavors, one with a built-in 50W amplifier and one without, requiring a hifi system hook-up. The portables come in two flavors as well, Play:5 with a 5-way speaker and Play:3 with a 3-way speaker. As with Squeezebox Boom and Radio, sound quality is on par with a good transistor radio or iPod dock. The Sonos sales department is slightly less realistic in their appraisal of these players than Logitech’s ditto but still it is never touted as a hifi system per se and can never replace one. The Connect and Connect:AMP, however, are full fledged hifi components. The Connect attaches to an existing hifi-system via line-out or digital and the Connect:AMP just needs a pair of speakers for its 50W internal D-class amplifier.

The amplifier in the Connect:AMP is adequate at low volumes but falls short when pushed. We thus opted for the Connect sans-amp and wired it to our power-DAC. In that constellation, the Sonos Connect sounds brilliant and indistinguishable from the Squeezebox Duet [given the same 16bit/44.1KHz files].

All Sonos devices can be wired or will communicate with each other over its own wireless network. At least one unit needs to be wired to form the hub of Sonos’ proprietary wireless mesh. The idea is that using this mesh of devices, they extend the network autonomously instead of relying on regular wifi coverage. This is probably the single most important factor in Sonos’ inherent stability. If there is no wired network connection available near any of the Sonos players, you can buy [at a very low cost, in fact] the aptly named Bridge, which is basically just the network part of a Sonos player. It doesn’t do anything other than form a bridge between your wired network and the Sonos mesh.

Unlike the Squeezebox players, none of the Sonos devices come with a control panel, save barely adequate mute and volume control buttons. There is an optional remote control with a touch screen that pretty much behaves like a bulky but [granted] very responsive PDA. Luckily there is also an app for iPhone/iPod/iPad and Android, and a desktop application for Windows and Mac [none yet for Linux, though]. As with everything else, these controller apps are extremely simple to use and share a common UI. Install it… Connect to the Sonos system… Play music… Unfortunately the simplistic approach also opens up a few ensuing flaws: It will recognise [a very limited selection of] uPnP servers but not allow them to be named. If there are more servers, you cannot remove those you don’t want. This may sound slightly nitpicking but is in fact rather annoying, since using a uPnP server is the only way to get around one of the system’s 2 foremost restrictions, namely that of a max of 65,000 tracks in the music library (a mere 5,000 discs) and missing support for multiple genre tags! And this is where Sonos becomes a pain to live with. There is absolutely no way we can shoehorn our music library into single categories. If you don’t listen to classical or folk or rock or blues or dance or whatever, one genre category might be enough for said “genres”, since not listening to classical music may cause anything with a violin in it to be tagged classical. If, however, you do enjoy specific genres of music, there is no such thing as classical for instance. A piece of music then takes on such categories as romance, etude, theoboer, lute, variation etc. The same goes for rock to a rock listener. There are at least as many sub categories of rock as there are in classical. There are live recordings and studio outtakes and tributes and covers and and and… No, without multiple genres, we have a hard time using the system at all. Squeezebox not only supports practically limitless amounts, it even lets you use them in filters and queries as [hopefully] explained above.

It is possible to stream an external source connected to a computer in Squeezebox, given a fair amount of tenacity. Sonos can do it out of the box on the Connect and Play:5. Simply connect something and choose the source in the controller app. Voila. It can even be set up to automatically switch to that external source when you connect something. This cannot be done any simpler. There’s a fly in the ointment as always, in that Sonos appear to broadcast the stream across the entire mesh indiscriminately requiring a very solid connection. Where we live there are more than 20 neighboring wireless networks making this feature effectively unusable without wired devices due to radio interference. The ability, however, to have external sources on all players and name them appropriately for all to play, is simply too good to miss and may usher me into cabling the lot however much that may defeat the purpose of the Sonos Mesh.


Unfortunately we didn’t get the opportunity we hoped, to put the Simpleaudio through rigorous testing. But that doesn’t mean we can’t have a short rundown of features. An actual test will have to wait.

simpleaudioSimpleaudio is the baby in the school yard, so to speak. They were formed in 2008 by former Linn MD Peter Murphy and fellow audiophile engineers that trickled over with him. Unlike Linn, Simpleaudio is actually a viable alternative to Sonos and Squeezebox. They have two players, one with an amplifier and one without. Both players have a wired ethernet connection or can be fed via a built-in powerline receiver. No wifi support. What appears a bit technically incoherent at first, is really quite interesting. If one player is set up with a wired connection or you use an external powerline adapter, all other players get their data from the power grid. Every bit as robust as the Sonos mesh and still without wrapping your house in twisted pair cables. In terms of media compatibility the Simpleaudio players is in par with the Squeezebox players, supporting up to 24bit/96KHz media with promised support for 192KHz in the future. If you are concerned with aliasing at these frequencies, however, you may be willing to mortgage your house to buy a Linn anyway.

Like the Squeezebox, Simpleaudio requires a computer running either a uPnP compatible media server or their own proprietary music library service. The former can be a NAS with built in media sharing, although compatibility may vary. Simpleaudio has no dedicated remote control at all. Everything is done from a Windows or Mac application, or from your telephone. Apps are available for iPhone/iPod/iPad and Android.

The controller application for Simpleaudio has one unique feature setting it far apart from the competition. It can separate music libraries between users. Your children can have their own libraries, so they don’t have to listen to Miles Davis but can settle for Teddy Bear’s Picnic instead. Similarly you can separate classical works from your contemporary collection. The Simpleaudio can handle 32 separate libraries, should you have the fantasy to name that many.

A Note on Sample Rates

High sample rates are often dismissed as voodoo due to our limited human hearing. Frequencies above 20KHz are simply not considered important. Sample rates, however, have nothing to do with sonic frequencies per se, but are a product of how conversion between analogue and digital works, or more precisely the mathematics of transformation between continuous and discrete information. Formulated in the so-called Nyquist-Shannon theorem, noise above half the maximum sampling frequency will fold back into the range below and create ghost audio that is indistinguishable from an intended signal. A compact disc is recorded at 44.1KHz. If the sample rate were set at 20KHz, which is the maximum frequency of a perfect ear, sound above 10KHz (half the sample rate) would fold back and cause distortion in the audible spectrum. By going above 40KHz this will no longer happen. Choosing 44.1KHz leaves room for a low pass filter to reduce noise above 20KHz, as well, I am sure, as fitting market-available crystals when the standard of Red Book was inked, and indeed put the data size of a full LP within the limits of a CD. However; making a filter with such steep cut-off slopes (high order) is difficult and will itself degrade sound quality. Increasing sample rates will help making filters cheaper and less impairing. One filter quirk which is rather disturbing is ripple; a response fluctuation both before and after the cut-off. Particularly the ripple before the cut-off is the cause of annoyance among audiophiles because it actually impairs the audio signal within the audible range.

When converting from digital to analogue the filter problems reemerge and we start all over again.

Audiophile extraordinaire, Michael Lavorgna, has written an extremely detailed yet easily understandable essay on filters which is definitely worth a read, available on Audiostream…


The setup that we have settled upon is one of two systems. We use Sonos in our daily life because it is easy to work with and sounds great. For in-depth listening the Squeezeboxes serve a purpose that could have been lifted by Simpleaudio but for which Sonos does not deliver. So, in fact, we have reached an equilibrium we hadn’t anticipated. They live together in perfect harmony.

The problem with multiple genres has been solved in two ways. All tracks have been fitted with a custom tag denominating the preferred genre [on Sonos]. When files change, they are automatically converted from their highest resolution to Red Book and in the process the genre tag set to this sonos-tag from the metadata database. First problem solved. All tracks now have just one genre as viewed from the point of view of the Sonos system but retain their multiple genres when seen from Squeezebox and other media players. The problem with sub genres must then be solved via playlists. To make playlists semi-dynamic we have mashed up a method where we can create .PLS files using the same system, so that each track is added to a set of playlists named from the genres it belongs to. It is not blindingly elegant but it solves the problem until that day when Sonos recognise the need for multiple genre tags. Second problem solved [sort of].

By the way; I omitted the relatively new Raumfeld system from the ‘test’ as it apparently isn’t available in Denmark where I live. It is a system to look out for, though.

Cambridge Audio Sonata NP30

Sonata NP30 Cambridge Audio have been lurking in the streamer business for years but have been hard pressed show any appearance on the shop shelves. Now it looks as if they are finally getting to a shop near me with their recently announced Sonata NP30 Network Music Player. The apparatus is neatly designed yet slightly on the conservative side of the front panel fence.

On the spec side the player offers 24-bit/96KHz playback of Flac and other formats through its Wolfson DAC, streaming from a variety of sources – wired and not.

As with everything else on this planet, the device can be remote controlled from the ever present iPad/iPod/iPhone.

Marantz NA7004

NA7004Marantz for me always stood for good old conservative ways and champagne colored aluminium bezels. Never as a technology frontloader. Perhaps that is the reason why they had me on this one. I didn’t see it coming.

Last year Marantz released the NA7004, which by a quick glance looks like any other Marantz component. But it ain’t! Under the hood lurks a three piece DAC, audio streaming and that all too rare Flac support. The NA7004 will discover DLNA compatible servers and play your music as the audio gods intended. It interconnects with other Marantz components and boasts a well laid out front. And HD? Well, it goes aaaalll the way pal.

Olive O6HD

o6hd_silver_front_angleOlive has been on the media streamer market for the better part of the market’s existence, yet hasn’t made much noise. Their latest initiative could be here to change that: The world’s first HD Audiophile Server. That is what they call it and looking at the specs, it’s definitely the world’s first something, even if others have touched on this before. The Linn DS is definitely up there (with a slightly more rabid price tag) and so is the NaimUniti Serve. The latter being a really attractive setup in its family configuration of server, players and mini players.

The device itself is cool if not exactly novel. The design is like other Olives, slightly unusual and definitely not very shelf-friendly.  The slanted cabinet has a touch screen on top and a handful of heavy duty connectors on the back. The front has a slot for ripping CDs. To get you going, the O6HD comes pre-installed with 12 HD tracks from Chesky records. Hand-built in America and all, it will look good on a serving table or something.

The power supply is split into two, to feed analog and digital circuits with each their own chill filtered juice. The DACs are 24-bit Burr-Brown PCM1792 supporting high resolution conversion of 24-bit/192KHz. It comes with 2TB of storage, letting you rip quite a bit of CDs, at least in 16-bit resolution. At full resolution it is not one byte too much. Unfortunately the CD transport is just that. A CD drive. It doesn’t support DVD or SACD so the only option for actually getting any HD content is to rip it elsewhere or download HD tracks.

A rather cool feature is genre specific tags. Only information pertaining to the specific type of music is shown in the genre navigation. That is really good news for classical music connoisseurs. Add to that a bit of color coding and a bloody nice glass touch screen, and you have a pretty nifty dashboard. The ever present iPhone / iPod Touch remote isn’t missing either.

Software rundown–part 2

In an earlier article, I had a quick run through of 4 media player applications. Apple iTunes, Foobar2000, WinAmp and J. River Media Center. This time I will go another set of players; a triplet that are not that much unlike the previous batch – at least not on the surface.

This week’s selection are: Microsoft Zune, Clementine and Logitech SqueezePlay.

Microsoft Zune

zuneMicrosoft Zune is not only a portable MP3 player. It is also the name of a piece of companion software specifically made for said player. It is, however, a quite capable software player in it’s own right.

Installing it can be a bit of a challenge. If the version downloadable from the official home page will not install, try and download the complete package from Microsoft’s download center – It is quite large but less prone to installation hick-ups. Unlike most of its cousins, Zune comes in both 32 bit and 64 bit versions, letting you take advantage of those RAM blocks above 4GB on your 64 bit Windows. Not sure that it makes much difference with this particular piece of software, though, but there you are.

Zune sports a minimalistic and classy user interface. Everything scrolls smoothly and has a high-key prettiness not often seen. Surely not your average Microsoft application look. On the UX side of things, this is not always a good thing – in fact, Zune is exactly as unintuitive as the majority of media players out there. Barebones and adequate. Not much more to say about this one, except for one thing: It doesn’t support Flac.

3 out of 5 for slick operation but few supported formats and no multi room.


clementineAmarok is a renowned media player for Linux and the antecessor of Clementine. It cannot deny its roots but at the same time it is curiously sleek and sports a fluent navigation many players could learn from. If you want a snappy interface that reacts promptly to your every command and a UI with no bells or whistles whatsoever, this one is for you. Add to that a thriving community and a promising future is ahead. It doesn’t do much in terms of remote control or multi room playing – but when it comes down to it, not many do. Needless to say, Clementine plays both Flac and Ogg Vorbis.

3 out of 5 for uncomplicated and slick operation but no multi room.

Logitech SqueezePlay

squeezeplaySqueezePlay is a PC version of Logitech’s (formerly Slimdevices) SqueezeBox media streamer family. The software version of the player ties seamlessly into the SqueezeBox universe and the SqueezeBox Server. The latter is responsible for managing your music library and streaming to your devices.  The wonderful part about SqueezePlay is not its tidy UI or abundant features but the fact that it can remote control other SqueezePlay’ers as well as any SqueezeBox you may have on your network.

If you don’t already own a Squeezebox thingy, installing this piece of software makes it very difficult not to want a Duet or a Transporter too. Previously the server (once known as SqueezeCenter) was overly complicated to set up and operate. This is all history. The server UI is clean and to the point. If you want to tweak advanced settings, you can get to them through little inconspicuous dropdown boxes – and quite frankly; you shouldn’t need to. There are some pretty nifty things hidden in the advanced settings, though. Among other things, you can make the server transcode certain file formats to save bandwidth or improve compatibility.

Sonos could learn a bit from Logitech here. Sonos have a desktop controller that runs on Windows and OS X. Logitech’s adds Linux and Solaris to the mix. The Sonos controller is exactly that; a controller. It doesn’t play music by itself – it just controls your hardware. The reason is fairly straight forward. Sonos don’t want computer savvy would-be customers create their own media players from scrapped PCs undermining their business model. Quite an understandable position, inarguably. Logitech’s approach, however, is equally understandable. They let you build your own stuff and as you do that you are left to wonder: Can I do this cheaper and more energy efficient? Yep! I can buy one already finished. I can get a kitchen radio, a kid’s room boom box and a Transporter for my Electrocompaniet in the living room. And they communicate. Not only among themselves but with my DIY media player. How cool is that? This is why I am prone to going the Logitech way instead of the Sonos ditto or indeed any third way. It is extremely modular. I can live with the fact that they are hoodwinking me into buying more stuff. I can live with that – ‘sure. One selling point that gives Sonos an edge over the SqueezeBox family, is their analog input stream. Logitech need to do that. They do. They do.

4 out of 5 for extremely well done inter-communication and cleverly hidden subliminal messages saying: *buy* *buy* *buy*.

Naim UnitiServe

UnitiServeWith the UnitiServe, British Naim completes their Unity system. The UnitiServe is a Windows XP Embedded based media server with a built in Red Book CD drive. The server supports a multitude of audio formats, including Flac at a resolution of up to 24bit/192KHz. The innards include parts from equally cool British lads, Digital Fidelity.

The main idea, of course, is for the UnitiServe to act as a server for multitude of NaimUniti and UnitiQute clients already casually spread across your house. It supports streaming unique content to 6 simultaneous receivers. But being a full fledged DLNA server, it will do the biddings of any compliant device on your home network.

The UnitiServe comes with 1TB of disk space or, if you so prefer, with only a 16GB SSD disk, requiring a NAS for its data.


HP Dreamscreen

hpdream The HP Dreamscreen is not an audio device per se but a good old fashioned picture frame with some unusual features.

As a picture frame it is rather above par in terms of picture quality and how it presents photos. It can show images from one of several built-in card readers or stream them from in-house media servers and even from HP’s own Snapfish photo service via its internet connection. For reasons unknown, it cannot stream video. That is somewhat odd since video playback is very, very good. The screen has an exceptionally wide viewing angle and very little ghosting. It comes with a handy little remote that can be parked in a small pocket behind the screen and hidden on-frame controls that light up when you touch it. Apart from getting greasy the screen itself does not have any touch capabilities.

What qualifies it for this short mention is not the fact that it shows your Facebook pals and all their weird ass twips to the world but the fact that it streams in-house MP3 music as well as internet radio stations and even Pandora*. Sound quality is next to hilarious but stick a pair of decent computer speakers in its headphone jack and you have yourself a nifty kitchen aid that gladly plays your favorite radio station while tickering your bestest friends’ updates. Or do as we do; export your own favorite Gumbo and Tamales recipes to a 4×3 image format and save them in a photo stream.

* Possibly due to its Pandora support the HP Dreamscreen is not available in Europe. A pity considering its other properties.

Naim UnitiQute

NaimQute The people who gave us the NaimUnity last year have gone and done it again. This time with a cute little device aptly and cleverly named The UnitiQute. The main difference from the NaimUnity is the absence of a CD transport. In other words, the UnitiQute is for those who don’t care about perloid plastic discs or those who have a plenty of sound elsewhere and needs an extension.

The front is sleek and minimalistic and very Naim.  The back panel abundant with connectors for all things digital and a few analogue for good measure. The UnitiQute streams from internet radio stations and from network storage devices, be it a regular NAS or that equally sleek Naim HDX in the living room. In addition to networked music, the UnitiQute plays music from attached devices, such as iPods and USB harddrives.

Flac support of up to 24bit/96KHz puts it well in the clear with the competition. With a built-in amplifier yielding 30W of smooth niceness it is fairly self contained and should fit any small living area. Put an HDX in the study with your Focals, a Unity in the living room and a Qute in the bed room and your retirement is pretty much secured.
