my rxv-4600 handles my setup just fine.

But, how big is your room? If it's really large you might want a dedicated power amp. I've freed up one of my Carver power amps and started using it on the m80's, but to be honest I really didn't need to. Ironically, even with the 80's off of the yammie, it still gets just as warm...anyways, I'm going on and on....

I wouldn't go any smaller then the rxv-4600 though.
