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?

If cable direction caused audible differences then the measurements would vary depending on the way it was measured. If those measurements show no difference but audible differences are still claimed then listening could be used to see if there is something the measurements are not picking up.
Perception of sound happens in the brain. I know there are some instruments being used to measure things like emotional response to music but no we can't measure all aspects of human perception to sound. This thread isn't about that but measuring the physical devices carrying the signals to the reproduction of the sound waves before they hit the ear.

" If cable direction caused audible differences then the measurements would vary depending on the way it was measured."


And the day we discover the device or method that can measure the audible differences a human can discern, your comment would be correct. Until then your comment is non sequitur

For the record, I have not heard a difference in the orientation of a cable. But there is no science known to man that tells us it’s not possible. Given the overwhelming amount of individuals who have experienced the phenomenon, I’m inclined to keep an open mind.


But djones is ready to pass this audible phenomenon over to bias. Perhaps also imagination. How would you like to live in that type of world? Tidy but dismal. 

So according to his last post, he allows for a variation in how individuals hear? Could he also be allowing for a variation in the process of hearing? Is it physical/mechanical or is it chemical or both? If he allows for variation he has dug himself a very deep hole.
