Schubert of course you know that we all tend to loose ability to hear highest frequencies out to 20Khz or so like most can when younger, so the gap between old rolled off tube gear and more full range gear heard back then was larger than what we would hear now.
I used to hear test frequencies of test records in my system up to 20kzh when a young adult. Nowadays I’d be lucky to get too much past 12Khz (I’m 56). "Air" ain’t what it used to be. That’s pretty much all one hears with music at those frequencies. Its a mixed blessing. "Air" is great but noise common at higher frequencies unless managed always drove me out of the room.
