Glad the Emo is giving you the improvement you wanted. I don't have an opinion on if you should return your amp, but just FYI my pro amp has never shut down or clipped. As JohnK will warn you, I listen at the louder end of the spectrum, but not near the hours you put on it. Just to help you survey the market. Good luck and enjoy.

($2,300 for faulty sub is a whole different story. I have a strong opinion on that one.)
