If you are using the receiver for surround sound in the family room in addition to the other zone, I would use the Onkyo TSX-609. It has a powered zone2, you can get an Onkyo iPod dock that integrates nicely, and has internet connectivity for additional music sources like Pandora. You get alot of bang for your buck. The Sonos is great too but you wouldn’t have surround sound and you would need an external amp to run multiple pairs of speakers. I would use the non-powered ZP90. Each setup would be around $600 retail.
