Ok great, thanks for the reply. Also, there is no other external amplifier necessary to power the in ceiling speakers if I am using connect:amps for all speakers, correct? I was talking to a local audio/video store the other day and he made it sound like I did? ...unless he was just talking about using connects by accident..
In summary, we just did a small house renovation, and while electricians were there I had them run wiring for in ceiling speakers. I want to be able to stream music from my computer and Pandora through the in ceiling speakers, as well as any audio that would be playing from the TV (shows, Blu-ray movies, etc), and control it all from my iphone. Also, I want to make sure that when I'm streaming audio through the in ceiling speakers, that it will also be streaming from the speakers and sub that are connected to my TV.
I plan on getting a Yamaha V775WA receiver, 1 Sonos Connect, and 3 Sonos Connect:amps. The 3 Sonos connect amps will power and control three zones of speakers in my house and the connect will be tied into my receiver and control and power the fourth zone, through the B output of the receiver.
From what I was told, the receiver can run audio through zone A and B simultaneously, which would also allow tv audio to play through speakers in the tv room (Zone A on receiver) as well as in ceiling speakers as well (Zone B).
