I’m sorry but this is horse shit. Double blind tests are there for a reason. It’s clear that OP does not understand how useful blind tests are and ist scientific purpose. He is probably an audiophile who was told that speaker wire do not make a difference when he bought overpriced cables :D
What cracks me up is that he is not technical so it takes him longer than usual to figure it out :D :D :D :D
He usually figures these things out much quicker but this time he is struck by some “not being technical” illness. As soon as it passes, he will figure it out as usual.
