thanks eldar. actually the mmg's are sounding better every day, just the way they are, using 4 ohm taps. bass is getting better and tightening up. plenty of clean, undistorted volume, actually more volume than i need. anyway, i think this amp is perfectly fine with the mmgs. and so long as i like it that's all that matters. it's a good amp, probably better than most people in this thread realize. too bad they can't hear it.....
