Mezmo,
With respect to the mid-bass hump you mentioned in your March 10 post, have you tried the DSPeaker Anti-Mode 2.0 Dual Core? I had a similar problem in my room -- I listen mostly to classical music and the resonance in the lower range of cellos was driving me nuts. The Dual Core took care of that for me. It's very easy to set up and use. Also, I think some dealers will allow a 30-day trial.
