So you think wire conductors in cables are directional? Think again...

Here is a very relevant discussion among physicists about the directionality...the way signal and electrons should flow... based on conductor orientation. Some esoteric, high-end manufacturers say they listen to each conductor to see which way the signal should flow for the best audio quality.

Read this discussion. Will it make you rethink what you’re being told and sold?

I’m not saying to measure anything. Just don’t cheat and use your eyes when trying to judge what you’re hearing. That’s all.
djones apparently doesn’t know how the brain functions in term of localizing a sound source. Both eyes and ears are needed for the brain to process and localize where the sound is coming from.


This is incorrect. You don’t need to see that a sound is coming from the front, sides, or back. Must you look at a surround sound speaker to hear that it’s coming from the side or rear? Binaural hearing is quite an amazing invention. Eyesight has nothing to do with it. As a matter of fact, lack of eyesight happens to sharpen that sense.

Perhaps you need to improve your reference with less elementary one....

My response was not about you.
You are very right about that....

But i am sensible to blatent distortion in a  public discussion....

The same also happened with volunteers who had been blind since birth, and thus showing that neither visual imagery nor visual experience is necessary for the primary visual cortex to decipher sounds.
Though interesting I'm not sure what this has to do with wire directionality. It does support the contention eyesight isn't that important in localization only the evolutionary area of the brain used for vision.

“During the study, we found that, although people with sight may use their visual imagination, those without sight, still used the same part of the brain to translate the sound, meaning that humans have a basic brain mechanism, independent from visual imagery and, more intriguingly, visual experience.
