Why don't you "tweak" your HK. Is it because you feel that you found the perfect configuration and now you're sticking with it?
I've found the perfect configuration for stereo but I always have to tweak my settings for surround. It's not the Denon but rather my source material and to some extent my room that necessitates this. Last night for example I was watching A History of Violence and I had the centre set to 0 and it sounded fantastic. The other night I was watching Unforgiven and I had a heck of a time with the centre. I had to tweak the volume, cross-over and tone controls.
And in PLIIx or Neo6, when I listen to music, I sometimes turn the centre off as I feel that gives me a better soundstage.
