I have an older Denon 1804 and it drives my M80s with out any problems what so ever. I have had a 3ohm load hooked up to it and still no problems. As Huztal said the recommended amps from Axiom are Denon, Sherwood/Newcastle, H/K, I know of a few that use Yamaha and still another very few using Onkyo. Your Receiver choice is not just Sony.
