Anyone know about Adcom amplifiers? I am considering buying one on ebay and am not sure what to get. I know that 2 channels is the way to listen to music,but I want to get a 5.1 channel amp that will sound good with music and movies. I'm probably going to add a center channel in the future. I currently have a Marantz cc4001 cd player, a Denon avr 890, and a pair of Definitive technology BP 7006's. I use my system more for music than movies.
