I am good. I am unable to suggest another logical explanation of the matter. Good stuff
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.

This is very humble. Almost Ethan Winer style 😉 dletch2358 posts04-30-2021 4:54pmHow about reading some of my posts and answering that question for yourself. |
All of the above (or below). And way more. He has Google

Except for you. Obviously. You have no biases whatsoever, and you are immune to all that 😂😂 It always amazes that people are so arrogant that they don't even accept that they have biases, and that their sited observations are totally prone to bias and that this arrogance goes so far to extend to insulting others knowledge, even though their experience and knowledge comes down to guesses and reading a few internet forums. |
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. |
I agree with Dow Jones (shocking!). As for me, I certainly expect the manufacturers to use instrumentation and measurements. Dah! Just as I expect them to use ears. Be it themselves, or “golden ears”, professionals who they can hire. At the end of the day, what they can come up with as a final product, can either be good, period, or tailored to their preferences in sound, whatever that is. That’s why trying for ourselves, in our own room preferably, is of paramount importance |
@dogiehoes --- or should I say "atdavid"? What took you so long to come back here this time around? And "only" 42 posts in one single day since "joining"? I am disappointed. You know you can do better. Light it up here! Many threads that need your attention and expertise. You need to reply to all of them |
You are right @cleeds — that guys has a lot of knowledge and would add value to the forums if behaved as a normal person. For some reason, he hates audiophiles as a species, and that comes clearly visible in all his posts. Even from back then in late 2019 when posting as AtDavid. And with every subsequent username including this one today. Clearly some mental problems, or perhaps going through a rough patch in his life. We will never know. But you can ask him when he resurfaces again 😂. One thing you can count on 100%, he WILL be back |
