Hang on, you said you did a blind test by singing into a mic. Now you seem to be admitting that was a lie and you just used samples others created on YouTube?!
No, you do not hear or feel the difference. The differences are way, way below audibility!
Of course you do! If your are going to come on to a public forum and effectively claim your hearing is 10,000 times more sensitive than any human being in history then you do have to provide some reliable evidence of such an astonishing claim!
Not at all, people who claim they can run 440,000kph or hear differences at 0.001dB are of course entirely sane!
If you are actually a sound engineer, then why don’t you measure the performance of the two cables or do a null test?
