Peete, welcome. My own M22s are used almost entirely for classical music listening, but I'd never limit myself to listening only with front speakers. Using a modern multi-channel receiver with a mode such as DPLII, the natural surround ambience which had to be mixed into the front channels in 2-channel source material(there was no place else to put it)is extracted and sent to the surrounds where it belongs. This makes for a very significant increase in the realism and enjoyment of music. Consider adding QS side surrounds
So, my suggestion would be one of the Denon or Onkyo receivers with Audyssey MultEQ auto calibration and room equalization. Any receiver rated around the 100 watt area would have more than enough maximum power capacity for the M22s.
