Thank You Gonk. I am only going to power the three front speakers with this amp. My rear are two Atoms that will be powered by my Yamaha RXV-730. These have a max power handling of 80 and I'm concerned that I will blow them if I hook them up to the 755. That being the case, I was thinking about getting 3 M200's. Do these amps sound better then the 755? Why would people buy separate amps like this and not just get a 2 channel amp?
