Except, it's never been demonstrated that 'hi rez CD' or

that can normally be heard between then, are more likely
due to different mastering choices.

Which may just reveal the limits of the current
(non-verified for musical evaluation) penchant for using
ABX for everything and declaring that it all sounds the
same.

There is no such thing as a penchant for using ABX for everything. A
statement like this shows a considerable lack of familiarity with how proper
subjective tests have been done since the middle 1990s.

Interested parties are directed to ITU recommendation BS-1116 and other
similar documents from international standards groups.



I think that what hlavo meant was that if a difference is noted in an ABX
test between an SACD/DVD-A mastering of a particular recording and the
Redbook version of the same recording, it may be due to differences between
the way the two versions were mastered rather than any actual difference
between the sound of the encoding methodologies.
