It's going to take way more words that have been spewed in this thread to-date to solve this one folks. Step it up!I cannot oppose that...
And i am guilty for the number of words...
😊😁
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.

Don't be fooled by a certain crowd who keeps insisting another crowd listens with instruments. That is just compensation for being unable to win an argument unfairly. There have been many correlations illustrated in audio between measurements and perception. There have been just as many illustrations for lack of correlation. This discussion is about neither, as is almost every discussion in this area. It is about audibility, something that requires no measurement, but does require bias free listening. |
I pity the fool who actually reads this entire thread thinking they will learn the answer on wire directionality. Kudos to maghister though for throwing the intellectual kitchen sink at the problem. At least there is some interesting topics there for inquiring minds interested in learning things even if they have nothing to do with establishing wire directions. Maghister you are a major step up from geoffkait when it comes to going on and on about nebulous products and solutions that only you can fully understand. Plus I am pretty sure you have nothing to sell and profit on as a result. |
As an engineer I can tell you don’t always rely on instrument measurements to decipher human experience.That's right, and your statement illuminates the unreliability of human experience as a component of quantitative analysis. Thus the field of psychoacoustics. People hear things differently, but that phenomenon is only loosely related to the nature of the sound origination or propagation vehicle. |
I pity the fool who actually reads this entire thread thinking they will learn something about wire directionality.nobody can throw light in that in few post anywhere... Kudos to maghister though for throwing the intellectual kitchen sink at the problem though . At least there is some interesting things there.You are generous with me thanks....I speak too much but the subject interested me and not for audiophile reason at all.... I dont need cables....I dont but costly one .... I dont have an opinion about direction but the problem is way more deep than the skeptic would want to admit.... |
