I have both the Connect:Amp and the Connect along with the Playbar, Sonos Sub and a pair of Sonos Play:3. I run my Connect to a Peachtree amp playing Audience ClairAudient 1+1 speakers. I have an older sub, Sunfire, connected to the Peachtree Amp. The Peachtree amp is in a different room than the Audience speakers are and I would like to use the Sonos Amp with the Audience speakers but it will not connect to the Connect as I understand it. The only workaround that I am currently doing is to connect the sub to the Play:3 which are in a different room, and then group them with the Connect. Not the best, but it works. I am hoping that this community has a better workaround that this one.
