I would invest in a more powerful power amp for my Maggie 3.7i speakers. Currently using Conrad Johnson solid state amp MM2275, 135 watts per channel. It does a decent job in a room that is 26 feet by 14 feet. However, I have read that more powerful amps really make Maggies sing. Curious if others on here have traded up to more powerful amps for their Maggies and how it worked out.
