I'm running a 9.1 set up with DSX Heights and Wides. I had intended for a 7.1 set up (with front heights), but ended up upgrading my mains from Energy RC-30 to RC-70, which is how I ended up with wides as well. I sometimes switch DSX on and off, and while I really appreciate the effect the height and wides bring, I could live with out them if I had to.

Proper position based on what? The guidelines from Dolby, DTS and THX all provision the surrounds at 90-110 degrees, which would put them at your side or slightly behind you.
