I have an old Yamaha 2092 receiver that I'm using in the bedroom system. I also have an even older Adcom 535 power amp that I'm not currently using. That amp was very conservativly rated at 60 watts per channel, but I understand was really pushing more like 80, with more dynamic headroom on top of that. If I were to run the Yamaha 2092's main left/right preouts to that Adcom amp to power the main left and right front channel speakers (Polk RT1000i), would that be an upgrade over the Yamaha receiver's internal main left/right power amps rated at 100 watts per channel for those 2 channels (especially since it wouldn't cost anything extra to do it)? Opinions please, and thanks in advance!
