Science doesn't care what you believe.
and, with respect, the people who make high end records don't necessarily care whether you are convinced they know what they're hearing or not.
there is the (relatively) famous story about Geoff Emetic complaining that AIR's new desk had a channel that just didn't sound "right' to him.
They took it out and benched it several times and couldn't find anything wrong with it.
Eventually, after he continued to complain, Rupert Neve came in (it was his design) and tested the module and discovered that it had an anomaly at 56k Hertz! Now anyone would quite sensibly 'argue' that no one can hear that high, and neither could Geoff.
But he clearly and repeatably, heard something that the anomaly in the super highs was doing to the audible range. Even though normal testing didn't show it and no one else could hear it.
Similarly, Record plant NY had 4 rooms. At one point Shelly Yakus complained that he heard something wrong with the power amp on the lows of the right speaker in one of the rooms.
they took it out and checked it, and it checked out perfectly. They put it back.
Few days later, Shelly is back in the room and again says "hey, that amp is still there. it sounds wrong".
So they swap out the amp and he's happy, and they send the offending amp back to the manufacturer (it's a Bryston) to be checked out.
Bristol finds nothing wrong with it either, no matter how they test it.
They send it back.
Record Plant puts it back into service but upstairs in the mix room, not back in Studio A.
Months later, Shelly walks into the mix room (for the first time in a while) hits play and immediately points his finger and exclaims: "There's that fucking Bryston!"
I don't discount the people whose work I know is stellar when they hear things I can't.
once again, "I can't hear it" and "most people can't hear it" is NOT THE SAME THING as "no one can hear it".
and if only ONE person can really hear it, then it's real.
It only means you're not testing for it correctly.
