I think the difficulty here is that "listeners" is a variable and so
is "test conditions". The test conditions would be not too difficult
to replicate, but the listeners could not be easily replicated, nor
could their emotional/health states at time of testing, even if they
were.

I would hazard a guess that the quality, aural acuity and perceptual
sensitivity of a listening panel could not be easily standardised, and
since the whole experiment depends on their aural perception, I'd
forsee this as a logistical problem.

Why would you need to? The only thing we're trying to establish is
whether one length of wire sounds different to another. To these
listeners, here, today. We find that they don't. So we try another
set, another place another time. They can't tell any difference
either. Anyone who thinks he can has an easy million dollars waiting
to be collected. It's been waiting a long time :-)

Is it cash or a cheque?
