For me I find much better channel seperation across the fronts using NEO6M than DPLII. DPLII seems to suck the sound into the middle sounding almost monaural, where NEO6M seems to direct more the mains. For TV watching NEO6M is definitely more of an enhancement.

For music, sometimes to take the edge of less than perfect recordings I'll try NEO6M when I'm not seriously listening (i.e. background music). But for serious music listening any of the surround modes end up sounding lackluster and ends up being haphazard in the overall musical presentation and balance (I know there's a better expression for that).

Just my 2 c's.
