OK thanks, that helps me better understand the basis of the problem, Dela Salla recommends having a dedicated 20 amp line to support this amp but I'm not sure even that would help, e.g., I just unplugged the amp from the power conditioner and plugged the amp into the wall (emotiva recommends plugging the xpa2 directly into the wall, presumably to draw current without obstruction) yet playing the same content the amp seems even more volatile, as if it is drawing even more power, which appears to trigger the protection circuit even more easily in response to a spike in power given dynamic HT content.
