I challenged:

"It would if you could quote JUST ONE such test that was done on
ANYTHING in audio, including loudspeakers, (see S. Olive's article
that I quoted to begin with) that had a POSITIVE result. N.B. *
Naturally it should be controlled (preplanned methods),
statistically valid (significant numbers),randomised
( not a preselected, trained group) and truly double blind.*
So far whenever people are tested by DBT/ABX method the reported
result is: "It all sounds the same"
How gross the difference has to be to overcome the ABX/DBT hurdle and
be heard by us peasants, the crossection of listeners?"

You dug up one reference dated #August 1984#!
"Here's one.
http://www.bostonaudiosociety.org/bas_speaker/abx_testing2.htm"

This was prof. S. Lip****z testing in 1984 one single witness:
Tiefenbrun developer and manufacturer of all of the Linn stuff:
loudspeakers, turntables and cartridges. Still active. A typical "
statistically valid crosssection of audio listeners, typically random
(not a preselected, trained group)".

Why would you want to exclude a pretrained group? You don't wanthe most
likely people able to hear what is being compared?

Right Mr. McKelvy? And they were
NOT comparing components but testing some rash Tiefenbrun statements
on matters of not the slightest importance to an average audiophile.

I guess I'm not average. I thought it was interesting that a loudmouthed
anti-digital idiot was shot down.

Right Mr. McKelvy?
And what was the upshot of this one and only ( you remember you said
you had "many")1984 test you managed to dig up from the bottom of the
barrel?
Lipschitz said:

I've been busy. I'll look more when I have a chance. Have you checked
witht he AES, BBC. any makers of hearing aid equipment or other groups that
have been using ABX?

Is it your contention that none of the above use ABX or DBT?

"In summary, then, ****no**** evidence was provided by Tiefenbrun
during this series of tests that indicates ability to identify
reliably:
(a) the presence of an undriven transducer in the room,
(b) the presence of the Sony PCM-F1 digital processor in the audio
chain, or
(c) the presence of the relay contacts of the A/B/X switchbox in the
circuit."
Experienced, trained manufacturer-developer Tiefenbrun failed.
Another NEGATIVE ABX\DBT test.
What exacxtly was the point?

Maybe things sound more alike than you care to admit.

Did you undergo a conversion and
tried to strengthen my hand?

What hand?

Or are you so desperate that you quote-
hoping that no one will check?

I thought you wanted a good ABX test.
