I am not a fan of Emotiva or the UMC-1 for that matter and the way this product has been handled. For what it is worth, I would never do business with them. However, I don't think they ever claimed the M80's dipped down to 1 ohm. That would be something though if they did. I have seen some claims on the Emotiva board that they dip down to slightly less than 3 ohms (2.7?). I don't know whether it was version 1 or 2.

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
