I can answer this one from the MMG users side. A couple of years ago, I ordered a pair of MMG's mostly because they were cheap, and I couldn't afford Quad ESL speakers. I tried them with a whole bunch of amps including the original ASL Waves which put out about 7-8 watts from each mono block. They drove the MMG's to moderate levels. I also used Quicksilver Mini's at 25 watts per channel. There is no doubt that a RM-10 could easily drive MMG's.
I'm still waiting to try out a RM-10. The MMG's weren't keepers.
