Time for another quick refresher - any amp (receiver, etc) can push any speaker (within reason) - speakers don't "draw" a certain amount of power - they're forced by the amp as far as they can be before the amp starts clipping and damages the speakers. The sound pressure levels you will experience are a function of:
a) Amp power
b) Speaker sensitivity
c) Listening distance from speakers
d) Room effects
I plugged your numbers into the little Excel spreadsheet I've got here for just that purpose and it looks like running stereo through the M22s with your receiver, you can expect peaks of 99dB SPL @ 5M (15 ft) away or 105dB SPL @ 3M (9 ft), I'd shave a bit off that to keep within a safe tolerance, though.
Is your amp powerful enough? For regular listening levels, probably, H/K are notorious for undervaluing their measurements, but receivers and watts are relatively cheap (in the 65-90WPC range) - might be worth a second look, especially if you ever think you'll want to put the spurs to it.
