If you read what I said, I am talking about the double blind tests advocated and used by some psychologists.

There is nothing wrong with blind or double blind tests where the question is whether you hear one sounding better. Since the null hypothesis is that there are no differences, you are rejecting the null hypothesis. In the choice of a 44.1 kHz in the research you mention entails hearing no difference between this rate and the music. It might have satisfied the Sony and Phillips engineers and allowed this rate to go forward, but any exception to hear no difference at any time, proves they were wrong.

Also if the variable assessed is not widely accepted as validly capturing that of interest, no amount of use of this measure gets researchers anywhere in proving their point.

It amazes me that audiophiles want DBTesting and would value it. I would be totally unresponsive to a conclusion that cables don't differ using DBTs with a 30 sec. exposure to sound and having to make the same/different choice.
