I just setup a sonos system running Rhapsody connected to an amp that distributes to 4 zones in my house. Running perfectly. Can't complain at all. My question is if i were to add a zoneplayer 90 to the family room surround sound setup, (which is not one of the zones the amp is distributing to), will the audio to the family room be in sync with the audio distributed to the other zones via the amp? The family room is right next to another zone and i don't want to have them un-sync'd. thanks in advance!!!
