    Compact and powerful with lots of options

    A few years ago we had speakers installed in the ceiling of most of the rooms in our home as well as outside in the sitting area. Long story short we stopped dealing with the installation company and never finished the project. We went into BestBuy to see what our options were and they recommended Sonos. The configuration they proposed seemed pricey and I just didn't understand why. After it was explained to us that we could the installation in pieces we went ahead with what we called the first installation. Oh my!!!! Why did we wait so long. It is so cool. My first surprise was all the freebies you get from Sonos such as access to many many radio stations. They are nicely grouped by genre. I was also able to play all the music I had purchased in MP3 format over the years as well. The second surprise was being able to run it from almost any smart device. There was no problem running it from multiple devices. I has the technician install Sonos on my laptop and told him I would install it on my other devices. I was able to install it on my Samsung Galaxy 3 phone, the new Samsung Galaxy 4 phone, my Nook tablet and the Samsung Tablet 3.0. We got two controllers and figured out on our own that you could group and quickly ungroup controllers. We opted to have two rooms on one controller and another controller control another room for a total of 3 rooms able to produce sound. This is so we could do indpendent listening but if you were having a party you could group all the controllers and they would play the same music without having to try and individually set each controller. We plan too add more but we can do that in a time frame that works for us. My only negative comment is that it seems from time to time a device can lose it's connection to the controllers. Sometimes you just need to reboot such as a phone and other times you have to just reconnect it which is literally pusing two buttons on the front of the controller. Not sure why it does this but it doesn't bother me. I like things that are easy, straight forward and make my life better.

    5.1 Surround

    • My Best Buy® Elite Plus MemberElite Plus Member

    So, if you have a SONOS SOUND BAR or SOUND BAR and SUB, you CAN achieve 5.1 Surround with non-SONOS speakers using the AMP. I did not want to use SONOS PLAY:X speakers because of the unsightly power cords and stands, so I went for Yamaha in-ceiling speakers connected with an AMP. The bad news, which I found out after installing the ceiling speakers, is the AMP doesn't have the same antennae as the PLAY:X speakers, so it does not know its connected speakers are surround speakers. This is stupid! And it's the big reason for the lower star rating. One must physically connect the AMP to the SOUND BAR with a CAT 5/6 cable AND connect one SONOS component to a wireless router. My AMP sits in a closet I wired the rear speakers to, so I had to run CAT 6 up the wall, thru the attic, and down the front wall to the SOUND BAR. Then, I had to buy a SONOS BOOST in order to connect to the router which is on the other side of the house. Then I had to set the system up in BOOST mode and change the IP of the AMP to point to the SOUND BAR. BUT, now that it's complete, OMG! The sound is incredible. I ran the Trueplay Tuning with the APP, made some adjustments to the bass, and BOOM. It knocks your socks off. My home theater sounds as good as or better than any commercial theater. And I like that I can set up the App to have separate sound settings for television/movies and music. Metallica never sounded so good in my house!!! Fix the AMP SONOS to not require CAT 5/6 connection, and this thing is a 5 Star product!

    Excellent audio source for my outdoor speakers.

    • Verified PurchaserVerified Purchase
    • My Best Buy® MemberMember

    The Sonos Amp has been an excellent solution to power my outdoor wired Niles rock speakers. I had been using an old 18 year old Onkyo receiver to power the speakers but it finally gave out. The audio source was my TV output utilizing Dishnet for Sirius and Apple TV for iTunes. I looked at replacing the receiver, but to get decent power for two pairs of speakers I would have to go with a surround sound model which I did not need. The other issue was that whenever we had guests (kids) who wanted to watch TV while others were out by the pool we had to turn the music off. Sonos provided the solution. I can now listen to a much greater variety of music from different sources (Sirius play lists per channel are not as long as you would think) without using the TV as an audio source, stream the music on a separate wifi signal in the house using the Sonos Bridge, control the volume (although I had already installed an outside volume control), and select different music from a variety of sources and devices. The sound quality is very good; better than my 18 year old Onkyo! The main drawback is price. I would love to add more components (play bar for the TV with the subwoofer and a Connect to hook up to my home theater in the basement) but I would have to spend an additional $1,750.00 and that doesn't even include the play bar mount for the wall which costs another $40.00!! That's on top of the $550.00 I already spent! The grand total would be $2,340.00 and I would be getting music in the family room, basement, and outside. For the family room to be able to do true surround sound for home theater, I would still have to spend more for rear speakers... Anyways, great system which I highly recommend...but be prepared to spend some $$$.

    Very good but lots of room for improvement

    Limited connections for input. You have to plug/unplug different devises unless all you want is internet fed content. The power level just makes it on the Amp for my Martin & Logan speakers outside (they are awesome). Any less power and it would be insufficient. A friend plugged in his iPhone and the volume was minimal...could not figure why since volume was on max for both. We just disconnected it. Internet range is mediocre at best. I also bought 2 Play 3 speakers, I really like them. The Sonos Boost Bridge is much, much weaker than reported. I also bought a Connect unit and needed the Boost Bridge. Without the Boost Bridge I would not have a network that works at all despite my new very high end Night Hawk router. The Geek Squad just squeezed out the connection with Boost and I am really surprised that the network isn't more robust or as robust as it seems to be reported on line. I have a large house and good thing I only was covering downstairs or it would never have worked. Just make sure all the devices are not too far away or the signal will be dropped. I do like it and enjoy the Sonos system. I wanted the sound bar to integrate TV audio but was told when you group with other speakers you lose individual speaker volume control, so I returned the sound bar and kept my Bose 135.

    I currently have 3 connect amps, 1 connect, the bridge and a Play 3. Every component is top notch. I don't know why i waited so long to get Sonos. Previously i was "trying" to play sound using the receivers different zones but that was not working out for me at all. Plus i have more zones than the receiver could handle. With Sonos, i can now play the same music from each zone, or group them to whatever combination of zones i want to create. Doing that is so simple with the app, even my not-so-tech-savy wife enjoys turning the music onto her favorite choice. You can play different music on any zone you would like, even from a different source. One thing to mention is that in order to listen to music from speakers that are connected through the reciever in my entertainment center (using the Sonos "Connect"), i have to turn my receiver on to that specific input. I use a Harmony Remote and have that labeled as "Listen to Sonos". Overall awesome product and i'm definitely going to add more Sonos gadgets to the entertainment center in my basement.

    A compromise......


    The ZP 120 amp only makes 55 wpc which is simply is not enough adequately drive many speaker loads. In fact, I could not find any receiver in BB that had a power rating so low, even a $179.00 receiver I found there was 100 wpc. I tried driving a pair of Snell bookshelf speakers (Type J) but the ZP 120 just does not have the goods to drive even a moderately efficient pair of loud speakers. At full volume, they were only modestly loud. It's also difficult to use banana plugs as the terminal ends really are not designed to accept them. No excuse for that! The ZP 120 is really more of a compromise of power and functionality vs. portability. If your not real serious about your sound or don't require even moderately loud volumes (depending on speakers). Than this might be for you. Considering it's $500.00 price tag, it does not give enough bang for the buck... It could be easily fixed - I hope they will address these issues in future models.......

    Sonos to the rescue for whole home audio

    • My Best Buy® MemberMember

    I bought a house that has whole home audio. For the longest time, I was looking at non functional in ceiling speakers and loose speaker connections, so I decided to do something about it. I did my initial research online and thought that I had to buy multiple components for a solution. i didn't want to do that so I put my research on hold. Then I revisited and browsed more forums and people were recommending Sonos AMP, an all in one solution! So naturally, my next step is to research the product itself. It got rave reviews and the youtube videos made it more clear that this solution was for me. Overall, I am very happy with my purchase. It definitely is an all in one solution in a small package (don't need multiple components). I've had it for a couple of months and it is working great, it has a premium feel, user friendly (passes the non-techy wife test), and the audio is superb. Now I have music from online sources (Spotify, Amazon, Pandora, etc...) pumping throughout the house. This product has my seal of approval!

    Great AMP for surround speakers

    • Verified PurchaserVerified Purchase
    • My Best Buy® Elite MemberElite Member

    I have a Sonos Soundbar and Sub installed in my home and was looking to expand to include rear surround speakers, possibly adding two PLAY:3 speakers. However, I had a pair of new, in-the-box, in-ceiling Klipsch speakers that would satisfy the requirement. The room was pre-wired for power and speaker wire so the job was a lot easier. The only downside was the setup. Sonos is typically a straightforward process with Sonos wireless speakers. In this case, it required a little more work. The only problem was the instructions with the Connect:AMP and the ones I found online were somewhat difficult to understand. I ultimately followed the directions found here: and here: Make sure the Sonos Playbar recognizes the Connect:AMP and tune the system to assure you get the best sound quality for the room.
