This thread shows again that quick judgements in audio are fallacious: what seems to add dimensionality and clarity in the beginning ends up being a bit of a sock over the tweeter after prolonged listening.
Or could it be that tweeters mounted on the front panel of a speaker rather than omnidirectionally have altered our auditory senses so much, that what might be removal of grittiness from EMI/RFI is perceived as overdamped treble.
Certainly worth a discussion, I wager…
