As you are only looking at the M22s etc, pick the receiver you like the best, but keep in mind that if you ever decide to go with a speaker in the 4ohm range like the M80s I would look at Denon and Onkyo as they are very capable of driving the 4 ohm load or at the very least make sure which ever receiver you choose has preamp outputs to allow a seperate amp to drive the mains \:\)
