Unfortunately it's my 12 wide x 30 x~7h foot basement. I was hoping to go class d to maximize availability of wall current. Minimize heat and noise and unlike 96 pound amps like the nad m25 or monolith 7 would ship easier. I'm open to suggestions though.What's your AVR model? and most importantly the room size? , 350W @ 8ohms is max ... and that's not a good way to go about it, as per my understanding.
The MiniDSP specs meet what you are stating,
IN: Unbalanced: 2Vrms or 0.9Vrms
OUT: Unbalanced: 2Vrms or 0.9Vrms
Balanced: 4Vrms or 8Vrms
Oh it's an onkyo txrz810 sorry... Nothing too fancy
