Wire is no Wire: The proof? You decide!

That is simple. It shows how biased humans are, that experimentally, as has been demonstrated time and time again, people will claim to detect a difference 75% rate when in fact the same component was presented over and over.
This is exactely why DBT listening is conducted. While some will say foul, this is a legitimate test method.

John Dunlavy has also tested his cable to the 12 ga zip with null results.

WRONG! Whatever was used to cover the zip cord to make it look bigger also made it sound better.

Seriously, the test may have its own bias. It could be the participant is just doing what he thinks he is supposed to do in choosing the big cable as sounding best rather than the small one. After all, isn't bigger supposed to be better? And wasn't the participant asked to make a decision? It also could be the participant feels the researcher prefers the big cable, and he wants to agree with the researcher or please him.

Wife buys a dozen brownies at bakery and serves them to husband on two plates. "Honey, the brownies on this plate I made myself, and those on the other plate are from the bakery. Which do you prefer? Husband tries each, and then remarks "Oh, yours are much better." Wife: Why do you like them better? Husband: "Well, they are richer and have more chocolate flavor."

Exactely, shows his bias, or is afraid to offend wife Same cookies, yet he claimed a difference for one, no matter that his wife claimed she made one. Yes, he is pleasing someone.
This would not happen in a DBT.

My subject was not blinded testing, but sighted testing comparing a zip cord and zip cord disguised as a fat cable. It was my understanding Dunlavey's test was similar. Given the nature of this kind of sighted testing, a participant's choice of the fat cable as the better sounding one, may be based on a desire to make a right choice or please the researcher, rather than on what he actually heard. Because these motives can be powerful, I would not conclude the choice was based just on the fat cable's looks.
