At my age I’m sure my ears can’t hear the difference but the “placebo effect” in my brain makes me enjoy the music more if I know it’s hi-res. (Similarly I really can’t see the difference between HD and 4K video but I still watch at 4K when I have the option.)
I think bit depth is probably more important than sampling frequency but I’m no engineer.
That is likely because you’re not sitting close enough to the screen, which is a common problem. For Full HD (aka 1080p, 2K), the optimal viewing distance is about 1.6x the screen diagonal. For 4K, it reduces to about 0.8x. For a 60in. diagonal, you should sit at most 48in. (4ft. or 1.2m) from the screen to take full advantage of 4K. There is a misconception here that higher video resolutions are about sharper images, when they really are about wider viewing angles and thus more immersive experiences.
A very good explanation and matches my thoughts and something everyone should take the time to read and consider. I am reminded of a line in a movie that goes something like “you don’t want the truth, you cant handle the truth”. For many audiophiles who have just paid big money on streamers and dacs that can process not only 24/192 but up to 24/ 768 dont want to be told that you cant hear it, makes them look a bit foolish, emperors new clothes syndrome. However, there is value in buying more expensive gear just because it looks and feels nicer so I myself would certainly buy better gear for that reason. Its a bit like buying fishing rods. A cheap one will do the job but one that has been hand made is just a pleasure to use even if you dont catch a fish.
A very interesting explanation and many truths and for us baby boomers who are flat out hearing anything above 10khz makes the quest for hires even more of a non event. I am curious though, given all the knowledge you appear to have, what hifi equipment you own.
If the original recording actually had some content above 20KHz (or a dynamic range that would not only destroy your ears but likely wipe out your neighborhood if reproduced at audible levels) then yes, something would be lost. A better question would be is something (anything) audible lost?
What would be lost would not be heard anyway. Then again, whatever is there that would be lost may not be music at all, just conversion artifacts, so it’s good it’s not heard even when it’s there.
