Rick, 2.0 and 2.1 music is where it made the biggest difference for me. I noticed it by accident when comparing my M80s and M22s which were sitting on top of the M80s. The M22s sounded richer and more enveloping than the M80s which baffled me so I put the M80s on milk crates and viola they also sounded more enveloping. Can’t hurt to put them up on something and give it a try.
I only had my center M80 up against the ceiling angled down at the listening position but I also thought that it made the whole front soundstage bigger. Never thought to put the L/R up higher (sounds like more experimenting when I get the house).
