You should have no problems driving the magnepans with your amps. I drove my 1.6's with a JVC 120wpc receiver (just to hear how they would sound) and they sounded pretty good. I used an Adcom 260wpc AVR and they sounded better at loud volumes. Now I drive mine with a 400 wpc Parasound amp and they sound great. And you can't have too much power with maggies. I asked one of the engineers at Magnepan about how much power is too much. His reply was that they will take all the clean power that you can give them.
