I’ve said it before and I’ll say it again. One test means nothing. Blind test, ABA, AB, what have you. A test cannot prove anything, but it certainly cannot prove that there are no differences among cables if the results are negative. Too many things can go wrong, even when everyone is on the up and up and trying to be thorough, etc. Geez, even disrupting the connections when unplugging and plugging cables during testing changes the whole playing field. Come on, people! No offense to anyone testing but don’t try to pull the wool over anyone’s eyes.
Lets start with some logic:
1. When normally hearing differences in cables a cable swap is required. So nothing is being done that already hasn't.
2. One test and the outcome only has value for the claimant. I've said nothing concrete about anyone else. I have said this emboldens my belief that others would perform about the same.
3. I can concretely say that in the system we had that you personally could not tell when the connections were changed.
So what is your confidence level in your ears only evaluation?
