I have a pair of very large Maggie's. I did drive them with a lm3886 for a short time. Then got a hafler 9270 to drive them and liked that better. Then got another 9270 and used one per speaker and liked that even better. With only one amp total for stereo the amp (9270) would go into protection mode after some long and loud listening. So, the myRef will not handle the job very long but at lower volumes it'll do alright. LM3886 did not end up in perfection mode because it was obvious that trying to get loud sound sounded bad so it didn't get played loud.
