I'm still not sure if folk that used to pay 500 quid* for a needle, needed their brains testing. As one who has noise damaged hearing, I'm still very critical about the tuning of a piano, and indeed the quality of the instrument, and all of this with a high-end limit of c 3,000 hz.
There has to be more to it than the simple gathering of frequencies and directing them down one's lug-ole. Holographic clouds of sound? Super-simulation in the brain? Dunno, but it doesn't make sense that I can hear what I do.
