I still love my RPA-2 amp driving my M80's, hasn't missed a beat.

I can drive the amp to clipping (red light comes on) but that has not changed since I bought them. And listening at that level while not painfull makes me wonder about my hearing over time.

The best part is the amp runs cool and listing for hours at loud volumes during parties never concerns me anymore.

Anyway I am sad you had such a bad experience. I would have been curious if it would have went to the right channel if you switched the speakers. Anyway glad to hear you are enjoying the M80's with your new amp.
