I want to make this point clear, I am on the side of those saying the Emotiva XPA-2 is a very good amp. A great amp when you factor the price verse performance aspect. And as a side note there customer service is by far the best I have encountered. If something not right they fix it period. This company has and will continue to earn praise from me. Now the Adcom is what I would call an anomaly. I clearly stated it was gutted and modded with new, bigger power supply, transformers etc... So this is "not your Grandfather's Adcom 555 Mk11" as they say. I praise the modded Adcom because to me there is something highly respectable about a amp (any amp) that sounds good and keeps on cranking no matter how loud you take it. But that's just my thinking. You might disagree. If there is one thing I've learned in Audio ED.101 is you don't trash or bash what you have not heard yourself. But again that's just my thinking as well. You might disagree.
