Default The case for ABX

Where are the equally scholarly pieces of research that show that some other
form of testing for audio differences have merit?

NYOB rides again. This time he's trailing a string of "references
collected from the files of his Public Library.
His "Case for ABX" is made up of titles such as "The Ears
gears"- the mechano-electrical transduction by hair cells"
But there are a few references that I recognize:
Greenhill on cables. Most of his panel couldn't recognize 1,75 db
difference in volume when ABXing. My old ears tell me when I change
one side by one db.- the image shifts. Overall conclusion: "Cables
don't differ.
.. Masters/Clark on amplifiers. Overall conclusion: No difference
recognized by the ABXing panel between amplifiers
Pohlmann on cdplayers.. This time a triumph for ABX. The very first
cdplayer (Philips 14 bits, soon universally replaced by 16 bits etc.)
identified. No differences heard after that first year product.

He quotes papers by Sean Olive and F. Toole. I have reprints of a few
of them:
"Hearing is believing....". No mention of ABX anywhere in the text
"The modification of timbre..." ditto.
"Listening tests..." Discussion on how to get better listening
tests: several chapters: rooms , material and double blinding- nothing
about ABX.
Sean Olive presented also: " A method for training listeners...".
No mention of ABX.. Emphasis on how much the listeners differ in their
ability to get trained.
There is something disarming about the man. One wonders whether to
blame him or pity him.

Those who oppose ABX (not the only double blind protocol for testing audio
differences) say that it is not valid and they have lists of reasons for
their belief.

What they do not have, is any research that some other method is as
revealing or reliable.

Where is the research that clearly demonstrates some other method works as
well or even at all?
