Well I think we can let this drop now, I just think that the technical standard should not be so close to the average human limits. Any way if we did up the sample rates and bit depth we'd need CAT9 cables :) *Players:* SliMP3,Squeezebox3 x3,Receiver,SqueezePlayer,PiCorePlayer x3,Wandboard

For us old dudes 20kHz bandwidth is more than enough:) 16k for n most cases . Last time i checked an audiophiles whas not a teenage girl musical prodigy :) they may actually hear 20k. I think the 20-20kHz bw includes most humans it would be truly exceptional very rare . And only applicable to

"Yes" recordings can be done at 96kHz for producing purposes . We are limited by our hearing usually below 20kHz so we reproduce what we can hear . Some argue that 44.1 kHz is a close shave hence 48kHz is/was used in recording studios the last decades . Thats a bit off the history i don't know
