After I ran Audyssey, I checked all the levels with my sound meter. And I don't have a DSP sub (EP350 v2).
My initial reaction after listening for a few hours to a movie is that the sound is fuller, but slightly colored and artificial. Not unpleasant, just more noticeable.

I started out with nothing & I've still got most of it left
