Default Compression vs High-Res Audio

[...] These people easily hear the difference between CD quality
and high-resolution audio. A DBT test made of such people, people who's ears
I know and respect, who told me that it was statistically impossible for THEM
them to hear the difference between the various sample rates and bit depths,
that would carry no small amount of weight with me. Also, like I said before,
if I were ever privy to a correctly set-up and executed DBT of this type, and
couldn't, in any statistically meaningful way, tell my own 24/192 recordings
from 16/44.1 copies of those recordings, then I would be convinced, and you'd
never hear me even mention high-resolution digital recording again. [...]


Well, the software to perform such test is AFAIR available for free. One
needs 24/192 recording, reduce it down to 16/44.1, upsample back to
24/192[*] (the information lost will to be restored) and comprare
original with processed audio using some ABX software.

No need for some expensive vinyl equipment, etc... Just some good 24/192
recording, and as I understand you have such recordings handy.

*] - upsampling step requires explanation -- some audio equipment can't
promptly and hands free switch sample rates -- that way there will be no
such problem, playbacksettings will be the same, etc. It isolates pure
16/44.1 vs 24/192 difference
