Douglas,
Congrats. Never heard of anyone passing a blind test for AC cables. Only failures.
But, the ABX was testing one leg of cabling, not the entire set.
I'm not quite grokking that. Could you be a bit more detailed about how you blind/ABX-tested the AC cables? I would love to see results between a regular, competently built AC cable and whatever high end cable you would have chosen.
I blind tested some Shunyata cables against a $15 off-the-shelf cable and could not detect differences in blind tests. I wouldn't think this would, or should, change anyone's mind about cables any more than your results would.
However, if after looking over your methodology, it looks sound, I would take your results as a data point in favor of some cables being audibly different. But, just as no one should take my blind tests as definitive, I wouldn't take yours - either of us could have made some unknown error. Which is why repeatability of the same results by other parties is a feature in science.
Still, for us measly audiophiles, we do our best and make our own conclusions from our experience.
And the results of your blind tests would also support the usefulness of blind testing. Lots of blind-test nay-sayers claim blind tests aren't, or can't be, conducted in a way to detect differences. So they think blind testing itself somehow erases the ability to hear real differences. Which is untrue as lots of blind test show positive results for identification. Some of mine were positive too.
