Directional interconnect cables

Carl109 nailed it. Electrons displace in both directions, that's how the electrical signal is propogated throught the wire; they have to move in both directions to send the AC (i.e. music containing) signal.

Hey, if our speakers and eardrums had to flow in one direction, well that wouldn't work for very long.

Ok, here you go, get some solid core silver wire, (the differences are more discernable then with copper). Mark which direction it comes off the spool. Make a simple twisted pair with the return and the signal running opposite each other. Be sure to indicate this on the RCA jack. Burn in the cable for a day or two on a cooker and then listen both ways. There is a difference, correct has a higher soundstage, greater high freq. information and ambience; wrong way sounds like there is a low ceiling on the venue that is being performed, bass is overblown, and HF info is somewhat MIA.

good luck and have fun, that is what is all about anyway.

Yes, wire is directional and I have confirmed that to my own satisfaction including eliminating dielectric and shield ground effects. Once burned in, changing direction of the cable is clearly audible. I know this proves nothing to you but if you try it you will likely discover the same thing.

Showing my ignorance here, but if analog audio signals are AC, how is there any directionality at all apart from shielding ground?

Showing common sense. IMHO. Wires are not diodes. It doesn't matter which way round they go. Shield ground point can have an effect.

How do you remove the dielectric effect???
