It’s just the same with vinyl: many of the better vinyls out there have content above 30-40kHz. The sonic result is, they sound "pleasant, smooth, enjoyable, real..." etc; in other words, vinyl was higher rez than much of the content we get nowadays!
I have a serious suspicion that frequencies above 20kHz and below 20kHz are more detrimental than beneficial to audio reproduction.I beg to differ, esp above 20kHz; the sense of space, clarity, and "smoothness" are directly influenced by frequencies in the upper regions. IMO it is redbook’s brick wall at 22kHz that makes it sound "harsh" rather than "crispy", "tiring", "truncated", etc. OTOH, hi-rez digital playback can sound very good—IF the original recording is comparably hi-rez, of course!
