Bob, as another example when I first got my M80's I was so excited to listen I hooked the up to my receiver and started to listen to some music. The speakers sounded like c**p. I couldn't figure out what was going on and was disappointed in my choice of speakers. It was then that I realised that I hadn't redone my calibration for the new speakers. the receiver was still set-up for my old ones. Once I did the recalibrating everything sounded great. I don't know if this is your situation but explore all your options brfore deciding yeh or neh.
