My mechanic actually is a good psychologist. That guy figures you out in one sentence. I am so happy that he happens to be great mechanic, too.
What do we hear when we change the direction of a wire?
Douglas Self wrote a devastating article about audio anomalies back in 1988. With all the necessary knowledge and measuring tools, he did not detect any supposedly audible changes in the electrical signal. Self and his colleagues were sure that they had proved the absence of anomalies in audio, but over the past 30 years, audio anomalies have not disappeared anywhere, at the same time the authority of science in the field of audio has increasingly become questioned. It's hard to believe, but science still cannot clearly answer the question of what electricity is and what sound is! (see article by A.J.Essien).
For your information: to make sure that no potentially audible changes in the electrical signal occur when we apply any "audio magic" to our gear, no super equipment is needed. The smallest step-change in amplitude that can be detected by ear is about 0.3dB for a pure tone. In more realistic situations it is 0.5 to 1.0dB'". This is about a 10% change. (Harris J.D.). At medium volume, the voltage amplitude at the output of the amplifier is approximately 10 volts, which means that the smallest audible difference in sound will be noticeable when the output voltage changes to 1 volt. Such an error is impossible not to notice even using a conventional voltmeter, but Self and his colleagues performed much more accurate measurements, including ones made directly on the music signal using Baxandall subtraction technique - they found no error even at this highest level.
As a result, we are faced with an apparently unsolvable problem: those of us who do not hear the sound of wires, relying on the authority of scientists, claim that audio anomalies are BS. However, people who confidently perceive this component of sound are forced to make another, the only possible conclusion in this situation: the electrical and acoustic signals contain some additional signal(s) that are still unknown to science, and which we perceive with a certain sixth sense.
If there are no electrical changes in the signal, then there are no acoustic changes, respectively, hearing does not participate in the perception of anomalies. What other options can there be?
Regards.

"When you set it to a temperature other than boiling..." Blasphemy! A kettle that actually boils? Proper tea-kettle is what holds water while fire is burning under it. Temperature is assessed by watching it get warmer. That fine art gets perfected over the years and becomes your second nature. At least it became my second nature. Which may tell a bit about my first nature. Yesterday, I saw a water bottle. One of those people carry around in fear of dying from thirst while walking around any city with two stores on each block. Rechargeable via micro-USB, two modes of operation (normal and adventure), ultraviolet-C light inside. Water bottle, as I said. "While you wait, give the bottle a gentle shake or do your best water dance to spread the purifying UV light evenly." I must be too traditional when I see it as a sign of decline of civilization.

Actually, to put it in simple words, direction of cables (speaker and interconnect) does not matter. By the way, it also sounds the same one way or another. I tried. In short, if you are so passionate about defending directionality of cables, go volunteer in local soup kitchen, read to disadvantaged children, or do something else valuable. "Grandpa, what are you proud of?" "I showed that guy on the Internet forum how ridiculous he was and that cable direction will give you blacker blacks." "I am proud of you grandpa. I want to be just like you." |
