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?

All of of you need to spend some time on a psych ward just to see some brains that are really not working right. This is neuro-psychiatry leading you all around by the nose. I have said this 100 time and I will say it another 1000 if I have to. You can not depend on what you and other people hear for these type of analyses. There are hundreds of psychiatric variables you can not control this way. In order to indicate anything these types of tests have to be controlled if they are not they mean babkas.
Directional wires are audiophile stupidity of the highest order. Show me one controlled trial with an adequate number of participants that shows otherwise. The same nonsense permeates the "tweak" world.  
The .3 dB limit of human hearing is right on. I spend hours adjusting frequency response in 0.1 dB steps and in direct comparison 0.3 dB is the limit of my hearing's ability to detect changes and this is switching back and forth between different curves. 
If you really want to improve the performance of your system and learn what you are doing in the process get one of these and get down with it.
