my xpa5 has run the 80's just fine for the last year running an average of 2 hours every day......And I love it!!!

cant tell you about the xpa2 because i have never used it. But from what I have read it is very "self protecting" which makes me think alot of the problems were user faults such as bad cables.... also we always hear the "problems" 1 or 2....we never hear the hundreds of others that worked fine.
I think emotiva should audition a pair of 80's to figure out if there is a problem. or axiom should do the same with the xpa2 \:\) Heck maybe I will get one just to see
