Or Outlaw. Outlaw makes some very fine equipment too at prices somewhat less than the equivalent Rotel & Odyssey gear. I was very seriously considering a pair of M2200's to drive my M80's. It just depends on how much money you want to spend.
I do still think that you ought to try to get Emotiva to send you another XPA before you call it quits with them.
And thanks to JohnK for explaining the impedance thing. I didn't know if it was something as simple as sticking an ohmmeter in between a speaker lead or if it was far more complicated. It would seem that 'B' is the correct answer.
