I'm running my V.P.160 through a 3 channel ADA1250 with my M80s it's a great combo. Much deeper than with my A.V.R. alone. As all Axiom speakers are tested with many times the recommended ratings, I suspect you'd be fine with even the ADA1500.

It comes to more of a how far are the speakers from your spot and how loud do you like it to be.

I don't get to crank it when anyone's home though when I'm alone you bet.

Reference level quick clean and shower or meal after work all the way.:
