Randy - the improvement in bass is the #1 thing I noticed when re-running Audyssey after the Dynamic EQ update (I have two subs now).

While this term is overused, the bass truly is smoother after the update. I find this particularly to be the case with Dynamic EQ turned on. It makes bass response at lower volumes much more natural sounding without any hint of boominess.
