My approach centers frankly on preference. Insisting
on "difference and difference only" may be a prerequisite
in research. An audiophile wants help to exercise his
consumer choice.

Mirabel's methodology has zero safeguards against false positives.
Furthermore, it is likely to generate them.


Secondly, while roughly level volumes between the
left and right side are desirable. Very exact levelling is not
necessary.

Unmatched levels are an excellent way to obtain the perception of
differences, even when comparing the same piece of equipment to itself.

Other common sense precautions a compare like
with like: testing a 400watt amp against a 5watt SET is
waste of time.

Not necessarily, as long as you operate both within recommended operating
limits.

You can not compare signal source
against signal source this
way ie. a cdplayer against a cdplayer, turntable against
a turntable.

More nonsense. Mirabel may not be able to conceive of how to do these
comparisions, but that speaks to Mirabel's lack of ingenuity, not any actual
technical limitation.

Same of course applies to ABX testing.

An illogical comparison, because ABX testing is not highly susceptible to
obtaining false positives, as Mirabel's methodlogy is.
