I personally subscribe to simple blind testing where the subject is in control of the A/B switch, thus eliminating any stress/duress and leaving the subject's mind more free to make a clear comparison...
I can see now why cable believers don't want to do any double blind testing. They're scared to death that their preconceptions might be disproved.
I am not a cable "believer" as you put it, but I do know that certain speaker cables can effect (but not "improve") the sound produced by loudspeakers by altering their FR. This is a scientifically accepted fact, you know that right? Whether they sound better or worse is a personal response which is down to the beholder. I personally don't mess about with speaker cables to change the sound, I change the electronics if I want to do that. Accordingly I have some nice Van Damme Blue in my system which cost me a few pounds per metre.
When it comes to digital interconnects I am a cable agnostic. I don't dispute the "bits are bits" argument as this can be measured and scientifically proven. I do however consider it possible that a digital audio cable may be susceptible to picking up unwanted passengers when moving those bits from a to b, and that any such noise fed in to a DAC's oscillators and other sensitive circuitry may induce jitter and other unwanted interference. Until this is proven to be a non-issue I am very interested in isolating any such noise. Alternatively I could spend my whole life as you do, doggedly refusing to try things until there is indisputable scientific proof either way. My way cannot hurt and can only improve my experience if my suspicions are right. Your way can at best not improve your experience and at worst could lead you to having an inferior musical experience.
Double blind testing is designed to confuse and is therefore widely considered to be problematic from a psychological perspective. The fear of being wrong can lead to the wrong answer being generated. The test in itself can generate the error. Blind testing, where the subject controls the switch and knows that he/she is listening to two different cables, would suffice for this type of test. If the cables sounded the same then the same result as DBX would be generated because the subject would still be guessing. If however the cables did sound different from one another then the results would be clear and we would have an answer.
