You could buy any of the models you list and be very happy. You have to consider ergonomics. FWIW I have the Yamaha rx-v2200 and it mates very well with the M22ti's. I did not care for the Denon 3802 as much, due to ergonomics, and the fact that it rolls off the highs a bit (e.g., cymbal crashes do not sustain as long as they would in real life). I think of NAD and Rotel as the next step (fewer features, perhaps better 2-channel stereo, but not better than Denon nor Yamaha for HT).
