Summary: I have the Sonos Connect, Bridge and Play3. All three products have worked wonderfully and were easy to set up on my wifi system. Not sure it matters, but the wifi is driven by an Apple Airport Extreme and I have a Sony receiver being driven by the Sonos Connect. The Play3 speaker, which I move around, is driven by the Bridge. I really don't have much to add other than to say I've been using the system for about 6 months and it has worked great. No problems of any kind.
Summary: I tried to get a receiver with built in AirPlay. I had a marantz and a pioneer elite. The marantz is best. I wish I had held on to that receiver. I have a pioneer elite in the 700 dollar range and I'm pushing some kef xq 20s. 2300 dollars later I had the stero working with AirPlay and AirPlay sucks in alot of ways - they have a long way to go yet with that. The sonos just works. It's the iPod of stereo components. Don't hesitate. Just get the sonos grin and bear it.
Summary: I have been interested in the Sonos system for quite some time and finally bit-the-bullet. Now I wonder why I waited so long! For the ease and convenience of having both access to your music files on the computer or a NAS system, as well as a wide range of internet broadcasts and services like Pandora and Sirius, the system is hard to beat!
