Thanks! I try not to be put off and I also try not to go into a debate, because I've done so in the past so much times, to find out the hard way its pointless to do so.

"There isn't a person alive who can hear the difference in the direction of such a simple wire passing alternating current"
Yet I've noticed that even non-audiophile persons have noticed and have explained in great precise detail what they hear from a wire reversal passing AC current - if the system is transparent enough. People who aren't technically educated hear it the easiest - and even as a background listening music from another room.
To listen to a wire's direction, you're best going to listen in MONO mode. Take your wire and put a piece of tape at one random end. Then disconnect the positive cable going from the speaker to the amplifier and connect the "test wire".
Listen to the first direction for some time, half a minute
Swap the cable
Listen again
Swap the cable
Listen again
Swap
Listen
On the wrong direction, there is a certain "dispute" with the sounds, lack of harmony and order, something like phase distortion. This is why to listen to vocals high harmonic instruments as piano, sax, violin.
On the right direction, the sounds blend together to make a harmony, a beautiful picture and you get the impression of a soundstage and depth, even despite it's mono mode.
"Take your wire and put a piece of tape at one random end. Then disconnect the positive cable going from the speaker to the amplifier and connect the "test wire". "
That part confuses me a little.
Do you mean that I don't use the positive wire of my speaker wire pair, I instead use a different single wire leaving the positive wire of my existing speaker wire pair disconneccted?
How do I make sure that the physical relationship between the single wire (that I'm reversing as I test and listen) and my existing speaker wire pair (of which I am now only using the negative conductor) doesn't change each time I conduct the test?
If the spacing and general physical orientation between my existing speaker wire pair and the single wire changes, that would cause changes to the capacitance and inductance between the two for each listening test and invalidate the test, no?
Thanks

"Still Working the Problem"
"Do you mean that I don't use the positive wire of my speaker wire pair, I instead use a different single wire leaving the positive wire of my existing speaker wire pair disconneccted?"-Yes, exactly.
"How do I make sure that the physical relationship between the single wire (that I'm reversing as I test and listen) and my existing speaker wire pair (of which I am now only using the negative conductor) doesn't change each time I conduct the test? "
-Because you don't change anything at the existing speaker wire pair, you only handle the test wire. If the wire pair makes changes to the sound, they are static, because they shouldn't change together with the direction of the test wire.
I'm giving the advice of keeping the speaker pair, because this is the easiest way to listen to a cable's direction. You need only one piece to make the test and it's quick and simple."If the spacing and general physical orientation between my existing speaker wire pair and the single wire changes, that would cause changes to the capacitance and inductance between the two for each listening test and invalidate the test, no?"
-Maybe yes, so just make sure your wire positioning is similar to the previous one.

aknaydenov you seem like a nice guy, so I will take you up on this.
If I hear a difference, I promise I will tell you and this forum.
Now the phase distortion could be measured, but I might have an issue with discerning "dispute" and "lack of harmony".
Can I use sinusoidal waves instead, or do I need music?
If I need music, can you recommend a specific track to use?
What about the other wires in the system, would they counter-act the wire being tested?
Is there a way I could test a single wire without using any other wires that might interfere with the test?
Thanks for your civility.

Garg0yleIf you wish to do a test, you are most welcome.
You do need music for a test.The best kind of cable to make a test from my experience is an unshielded RCA cable. Next comes the speaker wire.
You do not have to worry about the other cables in the system, of course if you are listening in mono mode.
I can recommend a well-recorded track with vocals and instruments that is familiar to you. The last time I listened to bobbin wire for my future PSU choke projects, I listened to John Lee Hooker - My Father Was A Jockey.
Classical music, especially operas are also a good choice.

OK I will get back to you.
I will probably make a jig and cut a length of wire in half, reverse one and have them connected to a switch so that I can quickly compare them.
I hope the switch is not going to cause a problem, in which case I may have to repeat the test with the switch reversed.

Although the switch is going to degrade the sound a bit, I think it's still okay to do the test with it.
Good luck with the test!
Thanks, I will get back to you.
