I doubt that you can hook up "too much" power to the M22's, but you can hook up "not enough". I've had that "not enough" experience just by buying a too cheaply made Sony receiver, from Newegg for about $150 a few years ago. Any decently made newer receiver that can supply from about 60 to 200 watts power should be sufficient for them. My receiver supplies 110 watts per channel and it is more than enought for my system.
