"Actually I thought humans are insensitive to phase relations, modulo inter-aural timing at low frequencies for spatial location. Perhaps that is what you meant? But spatial location isn't the same as the frequency-fetishing audiophiles go for." Au contrare...frequency accuracy vs spatial resolution is the classic Uncertainty principal in high end. A real high-end system present the ear with a truly 3-D soundscape...some instruments are clearly in the foreground, some are clearly in the background, and some are even higher than others. With a good recording, the hall ambience is also there. Put a great live recording on a great high-end sound system and "you are there". -TD

Do cats buy a lot of audiophile equiptment :8=||

The human hearing system is capable of noticing phase relations at 100kHz rates.

Actually I thought humans are insensitive to phase relations, modulo inter-aural timing at low frequencies for spatial location. Perhaps that is what you meant? But spatial location isn't the same as the frequency-fetishing audiophiles go for. To do that well you need casts of the outer ear too.

You doing owl-type studies on auditory localization? Audio-visual mapping and plasticity? Making the cats wear funky glasses?
