Obviously you mean for yourself and your partner.
....uhhh, no....that was definitely a response to your post....which I guess I should have quoted....oh whoops...
Cheers
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.

@dulledge: The last time I posted the 96% figure, as regards what scientists recognize as an UNKNOWN, in our universe: you replied: "Anyone that knows anything about science knows that you could never assign a number like 96% to what remains a mystery as that would imply knowing exactly what we don't know. People not very good at science are pretty terrible at anti science rants disguised as pro science rants. It was good theater though." That made your total ignorance of the sciences and what Physicists, around the globe have recognized for decades, blatantly obvious. ie (again): https://science.time.com/2013/02/20/telescope-to-hunt-for-missing-96-of-the-universe/ and: https://science.nasa.gov/astrophysics/focus-areas/what-is-dark-energy Your ignorance of basic science wouldn't be quite so tragic, but for your pathetic posturings on AudiogoN's pages. My minor was Psych and though we didn't have Dunning-Kruger as a reference (in the Sixties); we often spoke of, "pseudo-intellects", as sad and to be dismissed. This time: you ignore the point of the post (Science is always limited to our instrumentation's abilities, knowing how/what to measure and the latest theory) and deflect to the Physics of what's happening on our planet. I've mentioned before, in these pages: those whose understanding of electricity is limited to the measurements and theories, conceived by the Nineteenth Century's (1800's) scientists, can't fathom how our highly complex/terribly fragile musical signals can be affected by our cabling/wiring/wave guides. Those of us that took advantage of available higher education, were taught by our Physics professors and lecturers, back in the Sixties (as opposed to those of Case's EE Dept), a number of electrical theories and experiments/proof (ie: Wave-Particle Duality, QED, the polarization of dielectrics, etc), developed/performed in the Twentieth Century, that open the door to a plethora of possibilities, as to why many of us observe (hear) differences in improved wave guides, or anything else we alter in our systems (NOT as though that was ever our Prof's intended application/goal). Even back then: we were taught that electrons DO NOT MOVE through a conductor, but rather oscillate over minute distances (within the atom), with an AC signal. The signal itself moves as a wave and ALWAYS toward the load. The Naysayer Church is too buried in it's own antiquated doctrines, to even allow for the possibilities that MODERN Physics proffers.
