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
Upsampling and downsampling generally uses non-linear
algorithms, such as sinc and polyphase, so your comparison
is almost guaranteed to be different.
