As someone who already has 12 zones of audio throughout my house. I have to ask, is it really worth the money to run all the speakers, buy the speakers, tie it all to a single point of failure?
I have 8 zones tied to one amp and it is all IP controlled. Single point of failure is the amp. Sure its integrated and all that, but here where the issue exists.
Sonos, which I now power 4 additional stand alone units and feed the other 8 with a Sonos Connect.
Sonos was far cheaper, could install it myself and is an open platform that frankly just works.
Instead of running all that speaker wire, run cat6 in pairs or quads and hook up 1 or 2 sonos in each room.
Far cheaper, easier and expandable. Sure in wall speakers are cool looking, but the sound sucks unless you go ultra high end and build proper backer channels for the bass.
Plus, all Sonos devices can be controlled by multiple users, one app. Group all rooms, they sync. It is pretty simple but works.
Best of all, if one sonos fails, the whole system doesn’t. And, best yet, you can move them around.
Just my two cents. Save the cost of whole home audio and go with Sonos wired. Play 1s are quite surprising in sound quality, but the 3s and 5s are solid, but older tech.
Also, if you are looking for ST to do IR, look elsewhere for now. Use a 3rd party controller. FYI, the lync has serial control so that means it can be 2 way integrated instead of IR.
Good luck. I’ve dealt with the pains of whole home audio, and if I was to do it again, I would go decentralized, like Sonos. Cheaper, easier and far more reliable.
