Well our technology is not all that and a bag of chips. We still use fossil fuels and can barely get off this planet in a rocket. Science can't prove what we hear because science has not advanced far enough especially with sound. Take the late Julian Hirsch. Bless his heart he was only trying to take the mystery out of our components. If it measured good . ITS GOOD!!!. Now we know he was wrong because a component can test bad and sound great. So all these so called test instruments can't correctly tell which component will actually sound better than another. Remember the THD wars of the 70s and 80s. Manufacturers got THD levels real low to prove their product sounded better than the competitor. My point is, that relying on test instruments is not so cut and dry. Not black or white. We need more technologically advanced methods for cable testing.
