Has anybody a comment on how come nobody noticed, by listening (it was
found, apparently accidentally, by someone who was looking at the
frequency
distribution of some of the files he'd downloaded), that HDTracks and
other
web-based music selling services were (inadvertently?) selling up-sampled
16-bit/44.1 KHz material as "hi-rez" downloads and charging $20-$30 an
album
for them?
Some private individuals and a few people in the business noticed this a
number of years back.
For example:

(apparently from a 2003 AES convention)
Could it be that there is no AUDIBLE difference between
16-bit/44.KHz material and so called hi-rez as was found by Meyer and
Moran
in their notorius ABX study of DSD, and that's why the fraud supposedly
went
unnoticed even by the people selling the music files?
How about that? ;-)
One other point has been made which is that the Meyer and Moran study was
based on commercial SACD and DVD-A recordings, a substantial percentage
(some say 1/3 to 1/2) were upsampled 44 and 48 KHz recordings. These
recordings would have of course produced null results that washed out any
true posistives from recordings that actually had the bandpass we have every
right to expect from high sample rate recordings.
