Directional wires/cables

I would interpret "immediately" to mean small fractions of a second after flipping the switch, after the energy in the lines has completely been absorbed by the load.

I think the answer is instantly. The switch is opened, Games over.

Just questioning the "one way direction" of energy in an alternating current conductor, but that’s fine.

Not sure what you mean. The ac signal energy does not travel inside the conductor. It flows in the spaces between the conductors. The conductors are a guide for the ac energy to flow from the source to the load in the form of  electromagnet waves.

As for the electric charge, current, in the wire it is not moving back and from the source to the load. It is vibrating +  -  or  -  + hardly moving at all.

I'm sure @rodman99999 could explain it better than me though.

I might of missed reading a post on this thread but wanted to put in my two cents, just in case:)

I have made all my interconnects for around 40 years now. In the last 25+ I have only used Conare Star Quad which is dual twisted pair high grade microphone cable. One pair to the center contact, one pair to ground. Braided shield to ground on the input end, cut off and tucked carefully under the jacket at the receiving end. Silver solder, good connectors.

I have also used it for balanced cables.

Either way they are superb and I have never felt the need to go to any more costly cables even in what would be in today's dollars close to a $40k in gear alone for my highest end car audio competition build. ZERO noise, totally black background, very dynamic and ran as high as 20v balanced signals through them, 4+ volts single ended.

Well, I sure didn't mean to stir up such a hornet's nest but there has been a good amount of discussion and information to be read. 

I watched a video with Gene DellaSala and John Siau and what their thoughts were on the subject. They put far less importance on it than many others seem to. In the big picture, it does seem to be way down the line from other factors. I think this is fair as well. Once a person has every other aspect covered from TT (cartridge and all), DAC, CD player, whatever source you listen to, your ultimate power source, preamp, amp, down to the speakers, then maybe it's time to start tweaking with better wiring, power supplies etc. There is always something we can do to improve our system, so it seems. They don't suggest that you go out and buy the cheapest wire and cables that you can find either and I don't. 

Anyway, I'm moving on. Many thanks for all the insight.

My thinking is a cable can only be directional if it uses a floating ground.  The floating end should be connected to the receiving component.

It is a type of rf shield.

@stevencason Agreed. A floating shield is usually totally floating ie. not grounded at either end (just a terminolgy/interpretation thing I guess), and in this case I can’t see why direction of installation would matter.

A single-end-grounded cable might sound different if installed a different way round because of where any RFI noise picked up by the shield drains to. To my mind and in my experience, this is the only directionality which matters. I’ve never understood or experienced directionality in the conductors themselves.
