Mirabel's Unreasoning Bias

Krueger listed ably all the technical paramaters that
can create bias when performing a formal listening
session of comparing components..
Let's assume that one can follow his advice in home
conditions. Let's assumeme that Tom , Dick and Harry got
it all in place. You do a blind test. (Not a
homogenising, brain scrambling ABX. Please, have mercy)
Bias against ABX noted.
At the end of the day Tom will perceive some components
to be different, but Dick and Harry will say: "They all
sound the same".
Pure speculation.
And they will all be right: for their respective, genetic
endowment, musical experience and preferences. But
majority does not erase Tom.
More speculation.
=====================================
Krueger:
More speculation
I foresaw that trying to have a sensible (and polite) discussion with a
fair-market barker would be love's labours lost.
So I give up on today's Krueger and try to record some basics about
what is research and what iis "speculation".
For the hundreth time: You propose a method (you call it "a test") for
listening sessions to differentiate audio componewnts AS MUSIC
REPRODUCERS.from each other. (COMPARABLE audio components not 400 watt
transistor amp against a 7 watt DIY Heathkit.).
Next step: You present research to show that it WORKS. Research good
enough to meet the standards of a professional audio journal.(*See PS.)
You don't? Well, you notified the world of a pure SPECULATION on a par
with the mysteries of Sargasso Sea, the fate of Atlantis, the Loch Ness
Monster and the Unicorn. If on the basis of that huckster-fantasist
claim you market a gadget for sale, well....!!!
In the absence of valid research the door is wide open for
speculation.Mine is backed up by the results of all the ABX tests of
audio that appeared in the pop audio mags in the 80s. There were always
a few whose results were in keeping with their having heard differences
outweighed by the majority of null 50/50 guessers. Who was "right" ,
who was "wrong"? Door wide open to speculation because no decent,
statistically valid research was ever performed.
If my English isn't good enough to meet your elevated RAO debater's
standards I hope it will be good enough for a few others.

P.S. Just in case you're thinking of asking me again for $ 50:00 to do
your research for you I'll remind you. Univ. of Toronto librarian
found one aticle by AB Krueger NOT in JAES but in "Sound Eng. Mag." Not
about auditioning components but about:
:
"Amplifier-loudspeaker interfacing
Krueger, A. B.
Published in "DB, The Sound Engineering Magazine", Vol. 18, No. 7, Aug.
Sept. 1984.
Abstract: Examines ways of matching a loudspeaker and an amplifier.
Loudspeakers present a reactive load and amplifiers vary in their
ability to drive such loads. `Load lines' of resistive, purely reactive
and complex loads are shown. This chart shows the current that must be
delivered to the loads to achieve a given voltage drop. Power
dissipation control and reactive loading are also considered."
A great contribution to the subject. May I have $50:00 please.
The librarian added::
"Please let me know whether this is the author you are looking for. I
cannot
find any articles by author krueger, A. or krueger, Arnold on the
Journal of the Audio Engineering Society. If you tell me more
information about this author (subject field of his research, his
middle
name, etc.) I may find more articles".
You still have some time huckster-master
