I found decent amps at the 100-watt level did a fine job on the MMG’s. The MG 12 & 1.6 need amps approaching 200 watts to make them sing. Maggies are easier to match up with SS amps but the right valve amp makes a wonderful combo. The 7100 might be disappointing. If you don’t have the power to get the music off the panels the Maggies can sound, well, boxy, and that’s the last thing you want to do. I’d recommend the 200 mono amps over the 770 if you were going to use Outlaw amps. Other things to consider are what your going to “hang” on to the other 5 channels, the SPL your expecting and very important for Maggies is the room size.
