Just as a folow up, I ran some DTS tests on my system.

When I turned the center channel OFF, then DTS sounded the same as the full 5.1 sound.

When I turned the surrounds OFF, then DTS lost 6 dB of peak volume.

I have my mains set to large, and all other speakers are set to small, plus a subwoofer. There is no compression, but there is some type of change in either bass redirection or mix levels (or both) when the surrounds are set to off. I suspect it is simply bass redirection. Not sure if you get the same results if your mains are set to small.

Anyhow, DTS does sound good when you downmix. The downmix of DD sounds bad due that DRC downmix override function!
That is really strange. I alse tested the same and max peaks were always identical. I could turn off the center, surrounds or both - no change (and my mains are set to large too). AFAIK DTS doesn't contain any DRC info. Which movie (scene?) did you try and which receiver you have?
