@shurealltheway Good ask for the clarification - In comparison to the leather earpads, I would say the ultrasuede tightens up the bass signature and decreases the boominess. The impact is nearly the same but I prefer the tighter more precise bass. The ultrasuede also widens the soundstage without making them sound like (most) other headphones, it still feels like a good set of speakers and that crossfeed effect that attenuates extreme stereo R/L panning (think stereo Beatles albums) is still there. Meaning the R/L channels are still discrete but not distractingly so. Not as much of a hard pan. In comparison to the THX00 Ebony (my previous reference closed cans) the stereo field is narrower but feels more engaging. Hope that helps!
