i don't want to give away any trade secrets but if you could configure the setup to 5+widths plus 4 tops (a la marantz), you would immediately discover a whole new world. 7.1 bed highly overrated it dilutes the soundstage, Not sure how datsat handles, but worth investigating.
I'm not in front of my processor but I think I can exchange rear surrounds for wides .. and I have 4 tops.
Isn't the usefulness of wides a function of distance between surrounds and L or R? My L and R are in the room and not behind the screen as is my center. I already get reasonable phantom imaging where I would put wides.
