Ben, do you have any idea what brand of amps you would like to go with? Are you going to want to stick with the same series of amps?
I am currently using a 2 channel amp, and a 3 channel. I like this setup, due to the separate power supplies. My 2 channel is powering my M60's, and then the center powers the center and surrounds. With this combination, i have not had any lack of power issues. When i had a single 5 channel marantz MM9000 during some movies a couple of the amp channels would be driven into the clipping region. Since going to seperate amps, i have not had that problem.. However, i will say the new amp channels are over 2X as powerful than the Marantz.
Spearitsound, and accerrories4less are both good places to get a good value.
