I am getting ready to move a new house which is pre-wired for a main family room listening area (5.1.4) and 6 stereo zones. I have already bought a Sonos Connect. I want to be able to listen to the Connect in all 7 zones. I can hook the Connect to my AVR via RCA and then RCA zone 2 out to my Monoprice multi-zone amp. However, the AVR has be on when any of the zones in on this setup. I can also get a second Connect but that seems wasteful. Is there an easier way to do this? I think that an RCA splitter will be the cheapest solution. Is there one that you guys recommend?
