Bose gets the job done .

Alex from poway ,ca on 9/21/2017

I did a bunch of research and decided to go with this amp and run it with the definitive technology 251's. I went back and forth between a Yamaha receiver and bose speakers. I decided on this do to the ease of use, and the fact that you add on to the system down the road. I played around with the amp at the bose store and it was just too easy to play with . The app works great no issues what so ever. It's nice to play over wifi music doesn't stop when you get a call and the range is much better than bluetooth. I will build up my sound touch system with time.

Pros: Super user friendly even my wife can do it ...

Cons: Only complaint I have is that I wish you could do a zone a and zone b.

Crutchfield Customer Review (What's this?)

Great product for the purpose. I set up (2) SA-5 with (8) 251 Speakers. A lot of bang for the buck. Very full sounding system without a subwoofer. For this outdoor system a subwoofer just was not practical, and with the fullness of the SA-5-251 combo it was not missed. iPhone interface is intuitive and easy to use for the entire family. Setup was relatively easy. I did have a little hiccup when adding the second unit. I called Tech support at 8pm on a Thursday night. Tech that helped was EXTREEMELY knowledgeable. Turned out to be as simple as updating the firmware in the second unit.



Good sound

VirginiaC from New York, NY on 8/2/2016

Crutchfield Customer Review (What's this?)

This is an easy system to install and a lot more reliable than other Bluetooth speaker systems. I purchased this piece after going to the Bose store to figure out how to hook up existing speakers with my Bluetooth music stream.


Cons: The sound quality is an 8 out of 10. I might need to figure out how to adjust the speakers when I have more opportunity to play with the system.
