Niles makes multi channel amps that are really nice. I really like the 12 channel sherbourne. This could eliminate the multi speaker selector. My guess is that the selector is actually hurting the sound quality anyway. Older Adcom units tended to have "melt downs".
I'm using a really nice 2 channel amp with a top of the line niles selector and am very happy.
