Does it have to be a 5 channel amp? In my experiences, if you value music first, as you say, and you are happy with your Muse 160 amp, I'd just go looking for a used 3 channel amp to add to that for HT purposes. Just look for a nice little used Acurus 200X3 to handle the center and rear channels.
I have heard of those that like the Theta Dreadnaught, and to be fair, I have not had a chance to hear one. However, as someone who has always been a music first type, I never found a 5 channel amp that I could live with for two channel audio, and I have owned 5 channel amps from Classe, Proceed, and Krell.
