Tsk, tsk. One of the things that a good sound system does is not vary in tonal quality as the volume is varied: a decade ago most sytems were pretty atrocious in this regard; the latest offerings seem to be somewhat better. So impact, as in the punch of a drum, or the sense of the human voice being correct, will be maintained at low, very low volumes.3. He's listening at very high volume, and judging sound stage by impact and pressure.
4. All of the above.
I think a lot of the same effect could be accomplished in an HT system that has a number of those 'effect' settings, 'hall', 'music', 'club', 'party' type settings...

Will I open an old wound? Yeah ... why not! Tone control fiddling is another of those things that effectively, subjectively disappear or dwindle dramatically in importance when a system is up to speed, a phenomenon that I've noted for myself numerous times ...
