I agree that your points are relevant, me I prefer to listen to music that is 'psycho acousticly enhanced' by a wide lowpass starting at ~13 Khz -takes the edge off harsh vibes without affecting clarity or tonality to me.
...
It was you who inspired me most to use high bitrate abr (instead of cbr320) and to lowpass at 18.6 kHz which I actually do with my productive encodings. Thank you very much again.
eh, you know Im into speculation, you went on and checked that idea yourself Im glad its working for you

Because of this background I'd be very pleased to learn more details about your wide lowpassing. Sounds interesting.
This one is very personal. I imagine a world where lowpassing has not been possible, and people can only listen to transparent hifi. Then someone brings out a clean lowpass filter, its marketable as a technique which can electronicaly enhance sound to make it safer to listen to and less stressfull to the ears at high volume, yet not affect clarity. Because weve come from the other direction and technology has had difficulty extending the frequency range, full range is regarded as desirable, but if lowpassing was the hard thing to do, i think it would be the latest rage in hifi.
Considering, very few hearing aids (i dont need btw; ) go beyond 7Khz to assist clarity, cymbols, twangs, percussion doesnt suffer in loudness to me, until lowpassed under ~10 Khz, a sharp lowpass beyond 13Khz - I cant personaly even detect with my hearing, I use --lowpass-width 4.5 --lowpass 13.5 on my portable to ameliorate high frequency content past 9 khz.
It doesnt sound transparent to me, its a superior audio reproduction for my puposes.
With my own hearing I can happily go lower than this, but Im mindful of situations where other people listen to my playlist too.
If organising ambient cafe or party music or something, especially playing lossy encodings, I think it would be wise from a public consideration angle to use lowpassing or strongly reduce very high frequencies. Who would mind? people blessed with sensitive ears? I expect only equipment coinessures would complain about the bandwidth of the PA system, every one elses ears and atmosphere should bennefit, from 'pro-fidelity lowpass enhancement'
I cant vouch for the quality of lames' lowpass, though I havent come across any damning reports other than the apparent consensus that any detectability of lowpassing is comprimised and undesirable. Why should that be? do we really need the real thing, or even better than the real thing

?
On the other side of the coin, is the most disturbing activity of boosting the extremely high frequencies, so lazy cymbols gain the same dramatic impression as smashing glasses, way to fill the atmosphere with etherialy disturbing tweeps and meanies - gauranteed way to mess up a hippies trip.
Other than all that, it could be just a foible.
