AES preprint #3178: author claims to pass ABX/DBT for audi..

Anyone familiar with AES preprint #3178, "A User Friendly Methodology
for Subjective Listening tests" by Jon Risch, presented at the 91st AES
convention, October, 1991? I have not yet read it, but am looking
forward to doing so (admittedly with some trepidation). The author has
claimed that this article was prompted by his personal experiences as a
test subject in double-blind ABX tests of audio cables during which he
scored statistically significant positives.

I'm sort of surprised I haven't heard mention of this here before, as
Jon Risch and his methodologies do seem well-known around RAHE. Did it
already get debunked back in '91 when it was published? (I suppose I
should do a Google search.) Or is it considered one of the few
exceptions that prove the rule, i.e., a fluke?
