600sqft of space rates quite large in my books and the M22's with a good will work I would recommend going with those big chunky speakers but I like my M80s better than my M22's although the M22's are still one very sweet sounding speaker. You can't go wrong with any of Axiom's speakers.

Denon makes very good receivers so pick the one with the features you like and go with it. I would recommend getting one with preamp outputs should you ever decide to try external amps.
