Anyone that knows anything about the sciences, realizes that something like 96% of what makes up this universe, remains a mystery.
You believe in that science but when it comes to audio, all of a sudden we know nothing. But let me ask you this: do you worry about dark matter with respect to performance of your car? Do you know dark energy is what pushes your car ahead instead of a know chemical reaction?
If the answer is no, why on earth do you believe that putting a battery connected to one end of an audio cable makes it sound better? I mean are you not at all moved that when I measure this Audioquest cable, that I can't even detect a difference down to many decimal places with with the battery on or off?
Seeing how these companies don't present a single listening test research showing efficacy is not a concern to you? That any and all things must make a difference to somebody as to then keep the floodgates open to all of them?
Are you not concerned that some of these things do the opposite that is claimed? Here is a Nordost flat cable noise immunity test:
Compare that to cheap generic cable (watch the top right graph):
This cable not only costs a lot more, it is also a pain in the neck to use as high-end cables are almost always are:
Why can't you leave any room for independent evaluation of products showing issues like these? You don't take medication without such, why do you spend incredible amount of money on these audio tweaks this way?
Doesn't it make sense that it is pretty easy to make money by making a fancy looking cable and selling it for thousands of dollars? Just like a magic trick, isn't reasonable that your senses can be fooled enough to make a sale?
