LOL I best not get into an argument here I have been in more cable studies than you can count and conducted some tests when people claimed certain things they could not replicate in a blind study. One person claimed he could hear a difference in two identical interconnect cables I built. He could, half the time lol. I do not do pseudo science so I am often skeptical when someone says they cooked an AC cord and it made a miraculous difference lol. I got ahold of the same cable cooker and offered to give the person a dozen cables and all he had to do was tell me which six I cooked per his instructions. I then heard every excuse in the book why he could not accept the challenge lol.
I have also done blind studies on DACS, 6sn7 tubes (over 1500 types) and even boutique fuses lol. I go by what large groups can detect, but I did come across one young woman who could pick specific types of wire in blind tests, repeatedly. Mind you she does not know the difference between the wire types but she can pick an average of nine of ten wires correctly just by saying wire 4 is now in location 9, and wire 5 is now in location 2 as we switched 10 types of wire around in a blind test. I designed and built four identical class A tube amps we use for some studies and often we use Senn HD 800 headphones. High strand count copper headphone cables did exceedingly well in those studies when we used a group of 50 participants. In our system without knowing one item from another, one might score a 98 while another might score an 80 or so. One person might say a tube has a slamming bass or whatever, but this system requires many checks over the audio spectrum.
I work through and engineering department that helps set up some tests, others I conduct with my own equipment. We went so far as to have music recorded that we use for testing, they show off as many as 25 criteria so a large group knows what to listen for when comparing gear. The audio engineer who handled this for my local audio group is fairly well known in classical music recording.
My local group consists of at least eight engineers, five audio engineers, a couple physicists, and some random mathematicians and metallurgists. This can sound a bit boring but have also done such things as assembling the exact equipment used in the TV series Bosch, just to see what it sounded like lol
