OTOH, George Massenberg said this on rec.audio.pro relating
to work by him and Katz:

"An example of a useful, forthright listening test is the
high-octave
test suggested and implemented by Bob Katz, where he takes a
96/24
file (presumably rich in >20kHz content), and filters it at
20kHz or
so. Then he listens (through exactly the same hardware, and
under
exactly the same circumstances, removing conversion, to name
one
factor, as a possible variant) to see if he can tell the
difference
between the two (filtered and unfiltered) files. Can I be
brave here
and tell you the truth? Neither of us have had significant
successes
with differentiating between the samples."

Particularly note:
