I can tell you that the Axiom folks are not shy about cranking up the volume, so if they tell you the Sherwood will drive M80s you can be pretty sure it will drive them. If you want to play it safe get the receiver and speakers both from Axiom.

One of my friends (chips on the board) included a Sherwood receiver in his system (M60 based though). We didn't have a chance to do any sound quality testing against other receivers but I found it to be a very clean and easy to use product.
