Points 1 and 2 seem to be in conflict. I can't draw any conclusions
from those two statements without more information.
At what point did the listeners say they preferred the "audiophile"
recordings?
I don't have any links to the study that I read about, but in a study
conducted a few years ago, among hundreds of people that included audio
engineers, audiphile home listeners, people with no audio background,
etc... the data showed that when asked, the group correctly guessed
which source was 24/192 (as opposed to 16/44.1) something like 50.1% of
the time, with the audio professionals only being slightly higher.
Anyway, I would like to understand the two points you mentioned better.
They don't seem to make sense to me.
