Smooth treble

What is in fact a "smooth and refined treble"? Is that synonymous with treble roll off? Psycho acoustically an extreme smooth and refined treble can present itself like if there is less high frequency extension paradoxically. This is what one actually hears in the concert hall! In the concert hall one hears less "treble" than in the home (with your super high end rig). How can one get this smooth and refined high frequencies without severe treble roll off?
In my experience the older and more mature an audiophile gets, the more he/she wants a very natural sounding (overly refined) treble (not the bright, brilliant and super transparent treble many people want when they are making the transition from "mid fi" to "high end" audio) . Do you agree with this?
