I've my XPA-2 run my 2 M80s as mains for about a month now and have not experienced any shut downs. Before buying the amp, I asked Emotiva about the shut downs and was told to connect the M80s in stereo mode, not bridged. It was a few steps up in soundstage and clarity compared to the Behringer 2500 I was using to power the M80s before. I guess the Karma police has been nice to me. Hope this helps.
