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?

Tube dac/ versus S.S. dac, an already old war.... 😁

Why not defining good sound not by analog/digital war, or tube/S.S. ridiculous war, but by acoustical principles and experience in listening real natural timbre, beginning with the human voice ?

Why the result of Anton in reproduction of old 78 Rpm vinyls are so good?

Why are we together able to recognise this fact?

Because who are "programmed" by history, habit and evolution to recognize voice timbre...

Think about it...




 THEN we must forget analog tube/digital S.S. wars....Different implementations are different precisely.... And acoustic control could overpower anything if we bought a good tube amplifier or a good S.S. amplifier, or a good turntable or a good dac to begin with....


ACOUSTIC in neuro-acoustic science and in room acoustic is the key to audio....

Even for " our friend" who worked precisely in this field or near it but who erroneously think that human hearing could be reduced to a tool minus the consciousness.... Or perhaps even not minus consciousness via A.I.

I dont know him enough to speak for him.... 😊





The linearity of DAC doesn’t depend from output buffer tube of solid state.
It depends from chip used in the DAC or digital to analogue conversion method.
Triode tubes are much more linear vs any type of transistors as amplification element.
All good number achieved by transistor equipment are done used deep feedback that cause other even worse problems.

Well …. It looks like DLetch2 is gone. Whether banned or just quit on his own, I have no idea.

Honestly I am not surprised, following the previous patterns of this guy, most recently posting as Audio2Design, before that as AtDavid, Roberttdid, Dannad, and perhaps other names I lost track of.

One thing I guarantee is he will be back. Guaranteed. It will be easy to spot. Again. 
...and drone on he will...One can only hope that he‘ll find his inner self eventually.
thyname-

When that happens, let Tammy know. Report his posts, state in the reason his other names so she can suspend right away. 

Another one Johnnyaudiogoon, same thing. Tammy asked for help spotting him.
