Please read the articles about belief engine by a psychologist which I have posted couple of weeks ago. Since I strongly believe that cables don't matter much,I can never ever make out the difference even if subjectively proved. If you can prove it objectively then it's a different issue.
Indeed, the "belief engine" is quite powerful. As I said earlier, the same setup with the same cables, same amp, same speakers sound lifelike for my son but doesn't for me. The LEDR UP, DOWN work for him but not for me. I can easily pinpoint that the sound is coming from the woofer when it is supposed to play it at the bottom and the sound is coming from the tweeter when the sound is supposed to move up. I can always make out that artificialness in the sound. Initially I thought, that it was the high frequency response of my son's ear. He can easily hear 20 Khz test tone. Mine stops at 17 KHz. But then, I always enjoy music in a un-amplified live setup and I don't feel that the sound coming is artificial. The construction of your outer ear makes a huge difference in perceiving the direction of the sound. One of things I notice (in which I lose the sense of direction and the music sounds natural) is when I cover the back of the ear with my palm or turn the ear lobes towards the front. In fact, I even thought of making a music hat which covers the back of the ears and also patent it. A musical hat that would sell for few thousand dollars, cryogenically treated fabric, directing the silky velvety vocals inside your ears, etc. Using microphones, I would also be able to show convincing graphs which shows the difference (with the hat and without the hat).
Maybe for people like you and me, the critical thinking unit is strong and is immediately able to sense the artificial nature of electronic sound.
The Belief Engine - CSI
In the end, there always be a fight between cable believers and non-cable believers, atheists and non-atheists, our religious beliefs vs someone of other religion.
Beliefs are generated by the belief engine without any automatic concern for truth. Concern for truth is a higher order acquired cognitive orientation that reflects an underlying philosophy which presupposes an objective reality that is not always perceived by our senses.
The belief engine chugs away, strengthening old beliefs, spewing out new ones, rarely discarding any. We can sometimes see the error or foolishness in other peoples beliefs. It is very difficult to see the same in our own. Experience is often a poor guide to reality. Skepticism helps us to question our experience and to avoid being too readily led to believe what is not so. When people say let your ears be the judge, they forget that it is the brain that is the judge.
