I had that exact combination (604+M80s) for a month. It can drive the M80s, but I really had to crank it up. I had given a yamaha 2500 to my father in law and I made him switch me. I'd look into something mid end from last year on Ebay. Avoid HK refurbs-I went through FOUR 635s with them before just getting my money back to buy the Onkyo. Pity too because I loved that receiver. 2 died within minutes, 1 lasted 2 days, and the last one actually made it 6 days before dying.

The Onkyo is, however, a good unit. Simple to use, great menuing system. If it had preouts I would have lived with it and bought separates in a few years.
