This reminded me of another variable that hasn't been addressed yet (AFAIK).
In my case, I have suffered substantial hearing loss due to age, a part-time
musical career and a couple of head injuries. Further, my hearing loss is
not
"flat" in the sense of frequency...my resposnse curve has beem established
by
testing, and I have a notable "valley" centered around the mid-range
frequencies that are used to differentiate human speech.
This suggests that we might need to establish the "bandwidth" and frequency
response curves of the hearing of our test subjects; there is a chance that
their hearing and any difference from standard my colour their opinions!

I keep swearing not to re-enter this thread, then being foresworn.
No, Steven, you can play. Perhaps the most you would contribute is to be
able to say that when so much damage has been done, the digital and
analogue signals sound the same. On the other hand, if you are a critical
listener, even with those limitations you may well be able to hear that
they are different, though may not be as facile in describing the ways in
which they are distinguished.
Folks, you are trying to make this complicated. It ain't. It's about as
simple as it gets. It's just like proving there are as many apples in the
bag as there are elements in the field: give each elephant an apple until
you run out of one or the other. If you run out of both at the same time,
they're equal in number - or they were until the elephants started eating.
What we seem to be doing now is determining a measurement methodology for
apples and elephants which will determine absolutely their relative worth;
we're about to argue whether nourishment is more worthy than the ability to
uproot trees. But for the moment, can't we stop by finding out whether
there's an apple for each elephant with none left over?
