Right. It is not at all about reproduction of ultra-high frequencies (heck, my hearing beyond about 12kHz sucks and I have mild tinnitus). It is about moving the rate up for better sounding digital filters. All my CDs are fine--once run them at 384kHz or DSD256 into my DACs.
I hear you. BTW I have similar hearing issues to you, there are many of us it seems...hey-ho...
I repeat that 20khz sampling rate is not so DIRECTLY connected to 20khz audio reproduction. Sampling rate is about how many samples are taken of a waveform in a second and transmitted to a dac to reconstruct it in analog. Frequency of a waveform is how many times main peaks do follow each other in the same waveform. They're connected, but not in a direct and mechanical way, because a complex waveform does not have only main peaks and digital flow reproduction is not just reproducing main peaks. By supplying a more dense digital flow, dacs have more informations about the waveform to reproduce faithfully. That's one of the reasons why even Nyquist requires to double the frequency. But without taking into account dac's filters and hardware limitations (it's a 40s theorem, do you remember?); nor recent theories about >20khz HF effects on human brain, about 3D space reconstruction or good/bad feelings, for example (Science always goes further and yesterday's theories may be disproved by tomorrow's. Does someone disagree? Just try adding a 30/33 khz very simple rc low-pass filter - well above 20 khz limit so no roll off has to be taken into account - between your dac and its output stage and listen very well and honestly for a relevant amount of time, say 1 or 2 hours. Nothing changes? Please do it...)
BUT...
No problem, if you're ok that way, no need to change your mind, maybe you're perfectly right. No one in this thread ever said speakers are not of very high relevance for good audio reproduction.
I can live with you thinking your way. Can't you live with me thinking my way?

B equals 22.05kHz in case of hifi.

Boring.

Then this (very long, sorry, but it better fulfills scientific requirements):

That is Science: FIRST experiment, then try to determine the laws that explain the results.
Not the opposite.
So, you think that is smart doing experiment without any knowledge and preparation..
I think that one must have some ideas before experiment..
I never said that...
Are you trying to say that Queen Mary University of London lacks any knowledge and preparation? 😱
Are you assuming anybody in this thread does not have any knowledge and preparation, or ideas, every time he does not agree with you? 😕

I just tried to answer a question that was asked by an user. My answer was not liked by some of the others and the hassle begun against me...
I had to defend myself, didn't i?
Couple days of talking, but most still missing the point..
At least half of diyers believes that NOS converters are better..
You said first experiment..
I said experiment in the end, first books, knowledge and understanding..
Oh my God...
Need to state even the obvious..
This is a forum for audio diyers, not for homemaids... Who could build a diy component without even having some knowledge and understanding? Or some ideas?

You're missing the point - what half of DIYers believe is irrelevant. Those who do the experiment find NOS sounds better. Those who avoid doing the experiment pontificate about why that can't be the real result of the experiment.

Your wrote one thing, and think another..
Maybe some maid distracts you..
I agree.. it is irrelevant what most diyers find and believe that sounds better..
Hearing must be practiced, uneducated listeners between two always choose louder device with higher distorsion, and that is rule..
"Uneducated listener" is not how a many-years experienced audio diyer likes to be defined, sometimes.
Assuming many of the users of this thread are "uneducated listeners" is a bit of an hazard IMHO...
