Hmm thanks for the feedback, that makes sense, if you are right it may be a death knell for the combo of the XPA2 and M80s, funny though because a number of people are running the XPA5 without problem I believe some folks with the M80s, maybe just the M60s. I was hoping the difference in electronics between the XPA and MPS series was the culprit, the irony to me initially with all this was that the MPS1 has lower maximum output than the M80s are rated, I was hoping that the issue had more to do with a quirk with the MPS amp, perhaps not. The other monkey wrench is the fact that the emotiva folks state that the xpa2 is "a whole 'nother level" than the xpa3 or xpa5 architecture, perhaps the new level includes the protection circuit from an earlier (mps) level.
