The problem for me in attempting to start by measuring the threshold of audibility is that we don't know what to measure.The method you propose would work perfectly IF we could be sure that we are establishing the threshold of audibility for EVERY possible parameter. Obviously, there are things like frequency response, phase change, distortion, but is that a complete list? How do we know? What about responses to asymmetrical signals?
I guess I have a problem with the idea that we know at the outset exactly which things contribute to the subjective result. Perhaps that is the root of our different perspectives. That's the "circular argument" problem (IMO).
Since there are many reports of sonic differences between cables, but no successful measurements of signal changes (in interconnects at least) it's pretty obvious tht we are either looking for something subtle or the whole thing is one big audiophile fantasy.
How about this method:
1) Establish a comparison vs. a shunt.
2) Note the subjective characteristics of each cable vs the shunt.
3) Make every possible measurement on every cable, while mounted in the test fixture.
4) Look for correlations between the measurements and the subjective impressions.This at least begins to uncover the measurements that are related to sound quality, and should help eliminate those that have no impact.
Note that I am assuming that the comaprison-vs-a-shunt actually works. I've already expressed my doubts about that, since it is a slightly different usage scenario than the actual cable application.
