Welcome, Terry.
Gosh, you have a big bedroom!
My recommendation would be to look at the online manuals for receivers in your price range from major manufacturers (Denon, Yamaha, HK, Onkyo, etc.). Look more for features and ease of use than at specs. I don't personally subscribe to the school of thought that receivers at that price range with your equipment at normal listening levels would SOUND different. You might also check out (in person) the remote controls.
You didn't mention your display or sources; each could be an issue relative to the inputs and outputs necessary in your receiver.
With M2's, you will want to seriously consider getting a subwoofer of some kind sooner rather than later.
I'm a happy VP100 owner, and I hope you will enjoy your Axioms.
