We went from LPs and 8-Tracks, to Cassette Tapes and CDs, and now we live in the age of portable digital music. We walk around with portable digital music players (aka, "the iPod"), use cellular phones that double as digital music players, and even many portable GPS devices have built in MP3 music players. It's no wonder that technology has driven us in the direction of streaming digital music into several rooms of our home, from one central music source. Many manufacturers sell devices to stream music, via an Ethernet or Wi-Fi network, to multiple rooms in your home, and I have tried many of them. I have tested systems by Philips, Logitech, and Roku, but none can compare with the top-shelf Sonos Multi-room Music System. Sonos has been around for a few years now, and they have produced a few different device models. This review is for the fairly new BU150 model.

This package includes a Sonos self-amplified ZonePlayer 120, a ZonePlayer 90, and a beautiful Sonos controller. If you order this system directly from the Sonos website, they include a free charging cradle for the controller, which is normally sold separately. The entire Sonos music system utilizes a peer-to-peer mesh network, which they call "SonosNet 2.0." This wireless network is completely separated from your typical wireless b/g/n networks in most homes today, so streaming music across the Sonos network will not clog up your regular Wi-Fi network. SonosNet 2.0 also utilizes AES Encryption, so it is extremely secure. The SonosNet mesh network is designed to allow each individual ZonePlayer to work as a wireless repeater, so for every ZonePlayer you add to the system, your wireless range is expanded. Each ZonePlayer has 3 integrated antennas and Wi-Fi radios, and incorporates MIMO (Multiple Input, Multiple Output) technology. This makes for a rock-solid wireless music network that will surely reach every corner and floor of your home without any signal strength issues. The best part of this network is that you don't have to go through the frustrating process of configuring SSID and encryption codes to each device you add. Adding a new ZonePlayer is a one-touch setup, and the automated process takes only a couple of minutes to complete. You can add as many Sonos ZonePlayers as you want (up to 32), so that you can have music streamed to each room of your home. And yes, you can stream different music to each ZonePlayer if you wish, or you can pipe the same music to multiple rooms as well. The versatility of the Sonos Music System is almost endless, and yet installing and managing this system is about as easy as anyone could hope for.

When first opening the Sonos BU150 bundle, it can seem a little overwhelming. Not to fear, Sonos has made the entire process simple enough that anyone can handle it. The first thing I would recommend is that you plug in the Sonos Controller and get it charging, as this will be an important tool for getting the rest of your system up and running. You can perform most (if not all) of the configuration on your PC as well, but the remote controller really makes the process more fun and easy. The controller takes roughly 2 hours to fully charge. Now then, once your controller is ready you will need to connect one of the two ZonePlayers to your broadband router, via an Ethernet cable. You can then connect a set of regular speakers to the ZonePlayer 120, or a set of self amplified speakers to the ZonePlayer 90. The ZonePlayer 90 can be connected to any stereo receiver as well, using either the analog RCA outputs, or the digital fiber optic output. The ZonePlayer 120, which has a built-in 55 watt per channel amplifier, has a set of left and right speaker outputs, as well as a non-amplified subwoofer output (for those wishing to connect an amplified subwoofer for deeper and more powerful bass). Once the ZonePlayer is connected to your router and powered on, you then pop in the Sonos System Setup CD, and follow all of the easy to understand prompts to finish configuring your Sonos music system. If you haven't already installed the second ZonePlayer for your system, you can do so after the software is loaded, and simply use the "Add a ZonePlayer or ZoneBridge" selection from your PC software or using the remote controller. To add an additional controller, in the future, you simply power up the controller and follow the instructions that automatically come up on the LCD display. It's really that simple! Adding ZonePlayers for different rooms, and/or additional remote controllers could not be any simpler. The entire process is almost completely automated. Within a few minutes, and a few button clicks, you are finished and will have successfully expanded your Sonos music system.

Now I will not ramble on about all of the features and music services this Sonos system has to offer, but I do want to touch on just how fun and easy the system is to use. As I mentioned earlier, you can link multiple zones together to stream the same music to each room, or you can create separate zone playlists, and stream different music to each room. If you've ever used an iPod before, then creating playlists on the Sonos will be a walk in the park. Simply select which room (or actually which "zone") you want, then select the music you want (from your collection or from an online music service, like Rhapsody), and hit play. You can save these as Sonos playlists, or just let the selections play out without saving it for later. The Sonos controller really makes the entire process a fun and easy experience. It has a 3.5" color LCD display, scroll wheel and well placed buttons, which make navigation a snap. There is even a motion sensor in the controller, so it lights up as soon as you pick up the device. Of course the controller gobbles up power pretty quickly, so it will need to be recharged regularly. For this reason I highly recommend purchasing the optional Sonos Controller Charging Cradle (unless you bought the bundle from the Sonos store, which comes with a cradle in the package). Sonos can access your digital music collection from any PC, or from a dedicated NAS (Network Attached Storage) drive in your home. It can link up to your iTunes playlist as well, but is not capable of playing the DRM protected iTunes music. You can also access free Internet radio stations, as well as music services like Rhapsody, Pandora, Napster, and Sirius satellite radio. Of course those music services all require a paid subscription, but Sonos gives you a free 30-day trial for each of them to get you started. If you already have an account with one or more of these services, Sonos makes it very easy to login to your account and access the features of your paid subscription. Of course album art, song title, album title, and artist name are displayed on the controller's color LCD display, when available. Browsing for online music, creating playlists, and selecting tracks from your music collection couldn't be easier, due to the brilliant functionality of the Sonos Controller. The entire Sonos system is honestly quite thrilling to operate and enjoy.

Sound quality of the Sonos system is simply excellent. My only minor complaint is when using speakers with the self-amplified ZonePlayer 120, the sound seems a bit thin to me. Although there are tone controls for this ZonePlayer, the sound just isn't as full bodied as you get with the ZonePlayer 90 connected to a home stereo receiver. I guess it is just a matter of equalization, and hopefully something that will be improved with a firmware update sometime in the future. The ZonePlayer 120 is capable of driving both 4 Ohm and 8 Ohm speakers. If you attach 8 Ohm speakers, be sure they are able to handle at least 75 watts of power. If attaching 4 Ohm speakers then be sure they are able to handle at least 150 watts of power. Another interesting note is that if you do connect 8 Ohm speakers, rather than 4 Ohm models, then the Sonos is capable of driving 4 instead of just 2 speakers, if you so desire. Both will just be left and right stereo, so please don't expect a surround sound setup. There are only two sets of speaker outputs (for left and right, positive and negative wires), so to connect two sets of 8 Ohm speakers you need to hook two sets of wires up to each set of outputs.

I could literally go on raving about this system for several more paragraphs; it is really that great. However, there are a few things that one should consider before purchasing a Sonos Multi-Room Music System. First of all, if it carry's the Sonos name then it is going to cost you a small fortune! This is certainly true of the BU150 bundle. Depending on where you purchase it, you are surely going to spend upwards of a grand on this system. The BU150 bundle is only going to provide you music in two different rooms, so you may very well wish to expand this system with another ZonePlayer. The amplified ZonePlayer 120 can run up to $500, while the non-amplified ZonePlayer can still cost a hefty $350. Now an item that I recommend is the Sonos ZoneBridge (model BR100), which you can connect to your router instead of a ZonePlayer. The ZoneBridge is NOT a music player, but rather just a Network Bridge, which allows you to expand the wireless signal in your home. I prefer to purchase and install a ZoneBridge for connecting to the network router, since the router is in the same room as my primary computer (which is already hooked to a stereo receiver and speakers). This way I don't waste a ZonePlayer in an area where I don't really need one. Now you can use the two ZonePlayers (included in the BU150 bundle) in rooms where you want to stream music. The BR100 ZoneBridge will cost you roughly $100, at the time of this review, but it could save you the extra money of purchasing an additional ZonePlayer. Adding another controller to the system, which would be extremely handy when playing music from multiple rooms, will run you another $400. However, if you have an iPhone, Sonos and Apple have now teamed together and released a software application for the iPhone, which allows this mobile device to be used as a wireless controller for the Sonos music system. I can attest that this application works wonderfully, and is certainly a cost effective way to add another controller to your music system. However, I still much prefer the genuine Sonos Controller, and will probably shell out the bankroll to order one when I am able. So overall, just getting started with the BU150 bundle will set you back between $900 to $1000. I think most people will end up expanding their system (by at least adding a ZoneBridge) over time, so the cost of this system is not for the faint of heart. When you consider the high music system cost, in addition to the cost of your speakers and stereo equipment needed to enjoy this system, and finally add the cost of potential music subscription services (like Rhapsody or Sirius), you can clearly see that streaming music through your home with the Sonos system can be a substantial financial investment. However, as one that has tested many streaming music systems, over the past couple of years, I can honestly tell you that Sonos is the only system that has given me excellent results in every aspect. While other systems can be very difficult to install and configure, and offer far less capabilities, features, and overall music sound quality, the Sonos Multi-Room Music System has really stepped up to the plate, providing you with the very best streaming music system on the market today; and so they proudly charge you a small fortune for it. It is easy to install and use, is extremely reliable, provides a huge range of features and music sources, and offers up beautiful sounding music. So if you can afford it, the Sonos music system will definitely give you your money's worth, and then some.

So even considering the high cost, the lack of iTunes DRM music support, and the somewhat thin sound (lack of bass) produced by the amplified ZonePlayer 120, the Sonos BU150 Multi-Room Music System is a true 5-star product that is easy to install and use. It is one of the most reliable and fun to use streaming music systems on the market today, and I highly recommend it to anyone that can afford the investment.

I am an engineer so inherently I look for the value proposition in everything I buy. I have owned my Sonos for over a year now and had held off buying it for at least a year because I could not justify spending >$2K to transport music to different areas of the house. I was silly to wait because I absolutely love the system. I bought a flat panel TV and home theatre amplifier with speakers as well as a media center computer that stores all my music and video. After that big expense the cost of the Sonos did not appear to be that bad.
The connections were a no-brainer and all the units have worked great.
I have an unpowered unit connected to my 5.1 home theatre, a powered unit driving speakers in the yard, a powered unit driving speakers by the hot tub and an unpowered unit connect to a stero in the game room.
Having the ethernet ports for hardwire connections in remote rooms has also come in handy when I have work meetings here.
Storing and accessing the music is quick and easy. If I look to say that there is something that did not meet or exceed my expectation it would be that in order to get the album covers to appear on the Sonos unit, I have to go into MS Media Player and assign a jpg to the music files XML tags manually. But I can't blame Sonos for that.

I love music. I'm always singing a song or listening to one in my head. And I love all types of music. Rock, classic rock, classical, punk, some rap, opera, drumming, bluegrass, country, hard rock, metal, international, etc. I love it all. But, even with multi-CD players, you can't play them all and it's somewhat cumbersome. I was always jealous of friends who built their house and put in speakers to all the rooms, but my house was pre-owned and was not wired. Running wire to everywhere would require lots of demo; wasn't an option in my mind. Enter Sonos....

I actually heard about it several years ago and knew immediately it might be the solution to my situation. However, as others have said I was reluctant given the price to buy it. Man, was I stupid. I bought my first bundle earlier this year. I am so in love with this thing that I now have a combination of powered units and unpowered units in the following places: master bedroom, master bathroom, dining room, kitchen, outdoor patio (unit sits in kitchen, ran speaker wires to outdoor speakers), workout-room, family room and home theater. Yes, I have 8 zones. I have my CDs burned to a NAS that Sonos "looks" to. I also subscribe to Napster. I can literally play almost any song you can name, all at the touch of a button. It's like a gigantic, neverending jukebox. I live alone, so I just link all the zones I want to include and the music is just present in every room that I normally spend time in. I also use the alarm clock function on the controller; I wake up to my favortite rock playlist instead of an alarm. It has a sleep function too, so you can drift off to the sounds of your music in your ears. My friend's fight over the controller when I have parties. I truly consider this to be the best device I've ever bought, or a close second to my home theater which is also a big "wow" for people. But, I don't fire up my projector daily. This Sonos system I literally use every day for many happy hours. I can't recommend it highly enough!

I found out the hard way that the Sonos has a very serious limitation if you have a large iTunes library (or even several of them) that you intent to use with the Sonos. If you have more that 40,000 tunes in all of your playlists, Sonos will not import them. That sounds like a lot until you realize that according to Sonos one song appearing in four playlists counts as 4 (virtual) tunes!

I have around 20,000 tunes total in my iTunes Library but racked up ~54,000 virtual tunes across my playlists. The 'solution' to this issue was to delete playlists (aka forgo organization and ease of use) until the total number of virtual tunes was under 40K.

It is important to note that this limitation is across *all* music libraries that you want to access via Sonos. So, if in you family, your daughter has an iTunes collection, as does your wife as well as your own, you could quickly exceed the capabilities of the Sonos. When I asked a Sonos representative if this was a temporary limitation or one that was going to be fixed in the future the rather indignant answer was "No, we have no plans on fixing this."

Other, much less expensive options from Roku and SlimMedia (now Logitech) don't have this limitation, so if you have a large iTunes library you probably want to weigh your options.

Buyer beware.

The wife surprised me with this early gift to the both of us for the Holiday season. This sort of functionality/cool factor something the both of us have always wanted, so we saved and, at this price, it'll be the only gift given out this year...for either of us.

The setup is stupid simple. You plug-in and wire the boxes where you want them, power up the controller, press a few buttons on the boxes and you're set. Windows Media Connect sharing works perfectly through Windows Media Player 11 (WMP11), and this includes all the DRM wma files we've downloaded from the Zune Marketplace using our ZunePass. Unfortunately, WMA lossless files are not supported, so I needed to transcode my library to ~320kbps mp3 (yay dbpoweramp).

The controller utilizes an iPod-like interface, so it should be familiar to most people, and very intuitive to those who aren't (though I feel the Zune interface is superior in all respects).

I definitely give it a thumbs-up. Just be ready to drop some coin for the starter bundle, and cry if you ever want to expand in to more rooms.

I installed this system as a fully wired (cat 5) system in a living room and den, tied to a network hard drive in the basement. It took less than an hour to set everything up since my music was already on the hard drive. I was amazed when all my music showed up on the remote, in the proper categories (genres). The Internet radio worked well too. There were only a few flukes, such as when some jazz got classified as classical, but that may not be Sonos' fault. I have only a few minor quibbles, i.e., (1) it is easy to create a playlist but there doesn't seem to be a way to delete tracks from it. You have to delete the whole thing and start over. (2) If you are playing say, a jazz playlist and want to switch to a rock playlist, you have to clear the jazz playlist first. Otherwise, it just adds your rock playlist to the music queue, and you end up with a mixture of jazz and rock. Overall though, I am highly satisfied, and think the system is worth the rather high price.

I had owned the Squeezebox Duet for about a year, using it to control music in one or two rooms. (I have a wired connection between the two rooms, which I control with a manual switch.) Primarily I listen to music from the Internet-based provider Rhapsody. Although I liked the look and feel of the Squeezebox system and controller, it would not work reliably in my two-story home, where I have a wireless router upstairs and used a Squeezebox receiver downstairs. Every day or two, the remote controller would lose contact with the receiver (or maybe the receiver would lose contact with the router), and I was forced to try to reset the system. Sometimes this resetting process was relatively simple (just turn off the controller and then turn it on again, which takes a minute or so), but more often it was quite laborious, requiring me to re-enter the router's 22-digit security code by using the controller's wheel to scroll through all the possible combinations of lower and upper-case letters, numbers and punctuation marks. Even then, it would sometimes fail to connect, and I would give up in frustration. The Logitech support people were great, and they even gave me a brand new system to try, but it still kept crashing.
Finally I decided to try the Sonos system instead, even though it was considerably more expensive than the Squeezebox. I was able to save quite a bit of money by buying just 3 items: the Sonos Zonebridge 100 (which connects via ethernet cable to my router upstairs), the Sonos ZonePlayer Z90 (which connects directly to my amplifier downstairs; I'm using an optical cable which may improve sound quality), and an Ipod Touch 8 gB (2nd generation) as a wireless controller. I saved more than $180 by buying the iPod Touch rather than the Sonos wireless controller (actually $220, since I didn't have to buy the charging cradle for the Sonos controller). I'm much happier with this new system.
Setup was fairly easy, compared to the Squeezebox. Getting the iPod Touch to work as a wireless controller was the hardest part. After completing the setup for the Sonos components, which was simple, I connected the iPod to my computer which opened my iTunes program (I already own two other iPods). I had to tell iTunes not to synch my music to this iPod, since I plan to use this one only as a controller for Sonos. Then, in iTunes, I went to the iTunes Store and searched for "sonos iphone app." This search produced two results, but one was a podcast. I downloaded the other one, called simply "Sonos Controller" and then synched it to the iPod Touch using iTunes. After ejecting the iPod from iTunes, I began using the Sonos Controller on the iPod. At some point, I was prompted to enter that all-too-familiar 22-digit security code for my router, but this time it was much easier, since I was entering it on a virtual keyboard on the iPod screen rather than trying to use the Squeezebox wheel system. It was helpful to watch the Sonos video demonstration of the Sonos controller on an iPhone (found on the Amazon screen describing the Sonos BU150 Multiroom Music System) to see how to control volume etc.
There are several advantages to this Sonos/iPod system, compared to the Squeezebox, and two disadvantages. Advantages: 1) the Sonos/iPod system doesn't crash (But I did have one difficult problem after a few weeks of use: Rhapsody's list of my favorite channels stopped working and we tried removing the Rhapsody service from Sonos and then putting it back. When I tried to put it back, the Rhapsody server refused to accept my user name and password. Getting this fixed took 3 long phone calls to Sonos and Rhapsody and more than 24 hours of downtime.); 2) the iPod holds its charge for about 5 days with normal use, compared to a day or so for the Squeezebox remote; 3) it's much easier to search for music using the iPod's virtual keyboard, as opposed to the Squeezebox's awkward wheel, and this difference is huge, since searching for music with Squeezebox was so difficult that I almost never did it; 4) I can slip the iPod into my pants pocket and carry it around the house without fear of dropping it or accidentally pressing keys that might stop the music; by contrast, the Squeezebox controller is too big to fit comfortably into my pocket and, if I did put it there, I would be very likely to press buttons and produce some unwanted activity. Disadvantages: 1) the Sonos/iPod system cost me about $330 more than I would have paid if I'd purchased a new Squeezebox Duet; 2) the iPod goes into a partial shut-down mode after about 50 seconds, so if I want to adjust volume or change tracks, it takes longer (about 6 seconds total) to perform these operations using the Sonos/iPod system, as I must first turn on the iPod (by pushing a button and sliding my finger across the screen) and then wait for it to reconnect with the Sonos transmitter.

We've had our Sonos system for just over a year, and it's fantastic. Not perfect, but darned close. I've had to call support twice since we installed it, and both times was really amazed at how good the support was. Last time, it stopped communicating with our server computer (a Mac), at which point the tech support guy told me they didn't support wireless networking with Macs, only hard-wired networking, due to some tech issues. However, even though it wasn't officially supported, they could usually get it to work (ours had worked trouble free for a year at that point). He then took the time needed to solve the problem and get the system running again. That's right, he fixed a system that was not supported by the company, that's how good their support staff is.

Let me back up and explain the basic concept here. Wireless speakers suck. The sound is just awful. We were going to wire our house for sound and the installers suggested this system instead. It cost a bit more, but we are able to take it with us if we ever move. Basically instead of sending audio to wireless speakers, the Sonos sends digital music files from its "base station" to any of its "satellite" units. The satellites are, in turn, hard wired to speakers nearby. In our case, the main system is in our living room, the satellite is in our son's bedroom. From there, we ran the speaker cables to a switcher, and then one set to speakers in our son's room, the other set goes through the wall to speakers in the next room. One satellite, two speaker sets. Much cheaper that way.

We can play music from our computer, our stereo, or internet radio (I love the Radio IO stations, lots of variety and great sound quality for internet streaming). The wireless controller lets us run the system from anywhere in the house, or you can use the free software from any computer on your network.

In addition, there's a free app for the iPhone that allows your phone to act as an additional wireless controller. That free application saved me the $400 needed to buy a 2nd controller! We're doing some work on our house and will eventually buy one more satellite, which will integrate seamlessly into the current system.

Now, the downsides. Other than cost.

Ours is hooked up to our Mac. So, if we want to access our iTunes music, the computer has to be in awake mode. Eventually I'll get an external drive, put our music on it, and hook that up to our network, at which point our computer can be asleep or off and not affect the Sonos. Easy fix.

However, due to DRM issues, the Sonos can NOT play music you PURCHASE via the iTunes store. Most of my music is ripped from my CD's, so not a big deal. There is a workaround to iTunes music though, and I've used it successfully. Take the purchased music, burn it onto a CD, then re-import the CD into iTunes. Voila. No more DRM.

Note that tracks downloaded from Amazon's mp3 store work fine, no DRM on them.

We also use the Sonos with [...], at the amazing price of $[...]/year. Not month, year. Worth every dime. The unit also works with Napster and Rhapsody, we've used the free trials successfully, but I don't pay them monthly fees due to limited Mac functionality (I'd be paying the fees for Sonos use only, without being able to play the tracks on my iPod, etc).

The Sonos ain't cheap, but it's really an amazing system that I'm still in love with after a full year of use. If you can afford it, it's a no-brainer.

This is a cool system, and mine works great. I have it working with a Quad 12L powered speaker system in my kitchen, and having access to my entire music collection from the remote is amazing. The internet radio option is just unbelievable. This is something to get excited about. I did have a crash when I set it up intially, but I blame transferring about 140GB of music to my computer rather than the Sonos system. Once all that was entered, it has worked great. To my ears, it sounds fine, and I am using it wirelessly. I can run a cd player directly through it at any point if I don't want the wireless sound, but so far I have not noticed a difference. The convenience is great.

I bought this and a synology server so I could reclaim the ability to listen to my digital music anywhere in the house. Now, I have it and with this server and the sonos ability to connect to radio stations around the world and the awsome pandora music station, I am just in heavan. Easy to setup, works with 4 different setups in my house, home theater reciever, stereo reciever, stand alone with speakers and many types of speakers. Well worth it
