Magnepan like many less efficient speaker makers do not emphasize the benefits of more power with their products probably to not limit market or discourage customers. Less watts will work but you will run out of juice if the volume needs to go up. Current probably does not hurt but I did find Maggies not as needy there as with many less efficient dynamic designs. Tube amps even work well if powerful enough to get the volume you want.
My local dealer has sold Maggies for years and recommends Class D amps by Rogue for use with Maggies though they sell tube amps also.
