While bashing Denon AVRs elsewhere, you are ready to jump in to your elbows with a new product from the same company. Although Sonos does not integrate the way we would like, it is the closest thing to a trouble free high tech device we have seen. They have a ten year head start on making this thing work. I'll watch from the sidelines for awhile on this one. Haven't had a single client not like Sonos yet.
