You’re going to need one Amp per room to have an independently controlled zone for each room. For each TV, if not using the Playbar, you’ll need a pair of Amps. One Amp drives front left/right speakers and a second drives the surround speakers. The center speakers will be unused. Instead the front speakers act as a phantom center. In my experience with two TVs this works well. You won’t need the speaker Selector with this setup, but you may be able to use it if you want to switch speakers between a smaller number of Amps. By my count of your rooms and surround systems you’ll need to purchase 8 Amps for the full setup.

Thanks Dan. Very helpful. So is this the breakdown per amp ? 
 

front speakers tv room 

back speakers tv room 

kitchen 

dining room 

outside patio 

master bedroom front 

master bedroom rear 

master bath 

loft 

( 9 zones = 9 amps - 1 already owned = 8 to purchase )?  

Also , is there a way to connect the Sonos sub in the tv room to the speakers , or does that require another amp ? 
 

thanks so much !! 

Your plan for the Amps per room looks correct. I counted the Amp you own when I said you’d need to buy 8 more. The Amp can provide the signal to a 3rd party sub and can also bond with a Sonos sub, so you won’t need an additional Amp for that.

Thank you. 
so I assume the playbar , once moved to a guest room , would be basically just a “speaker” for the guest room tv and not on the Sonos app ? 

The Playbar would be visible from the Sonos app and can play music like any other zone.
