directional cables?

Herman, if you want to nit pick about the physics of energy transmission (which is NOT what my remarks here concern) then we can have that conversation privately, and not bore these folks. Is sounds like you accept that a cable (material) will conduct a signal the same way regardless of which end is used at the source and which at the load, or do you disagree with that?

As for the arrows, they simply indicate at which end of a single ended audio frequency cable the shield is tied to ground. This helps to select a common piece of equipment (usually the preamp) as the single grounding point for all the signal cables.

Placing arrows on other kinds of cables commonly used in audio, as if to imply their design is soooo sophisticated that their performance will be affected by their orientation, is a silly marketing ploy used to raise their perceived value in the eyes of unsophisticated consumers ;--)

I do know of one high end cable manufacturer whose glass digital data cables do render different analog results depending how they are installed. I won't even go there, God forbid I've lost my grasp on that technology as well ;--)

I've always found it amusing when a psuedo-scientist makes a claim about physics which is clearly wrong, backs it up with even more bad science when challenged, and then reverts to something like "you're nitpicking." How something sounds to you or me is debatable but this is science. It's not open to debate. It's not nitpicking. What ever happened to admitting you are wrong? Your claims about AC, distances DC and AC can travel, and energy transfer are just plain wrong. If we are to share ideas and hopefully shed some light on concepts that some are curious about we do them a disservice by letting false claims go unchallenged. And what about

If you disconnect the shield at one end, it can still drain interference to the ground end, but it can no longer conduct the 'minus' half of the music signal.

???? I missed it before but that makes absolutely no sense. You can't separate the positive and negative alternations of a signal with a cable any more than you can have a magnet with one pole.

That's it. You are wrong and it just gets worse every time you post. Sorry to everybody if trying to set the record straight has hijacked the thread.

"In direct current, the electrons do indeed flow in one direction, and thus "the load""

Nsgarch - electric current is a flow of charge and not a flow of electrons. Electrons move very slow - at about 0.1mm/s (drift velocity).

"As for the arrows, they simply indicate at which end of a single ended audio frequency cable the shield is tied to ground. This helps to select a common piece of equipment (usually the preamp) as the single grounding point for all the signal cables."

This is what Audio Note recommends with their interconnects as one end of the shield is tied to ground. Regarding the audible effects of directionality with this cable design, I recall once several years ago that I disconnected all of my cables to clean all of the RCA plugs and jacks. When I re-installed them something sounded wrong. As it turns out I had reversed one of them by mistake. Reversing it back to its original orientation was audibly much better.

Nsgarch - electric current is a flow of charge and not a flow of electrons. Electrons move very slow - at about 0.1mm/s (drift velocity).

I'm afraid that's incorrect. Current flow is indeed a flow of electrons. Electrons ARE the charge carriers, which is why we call this field "electronics" instead of "protonics."

The measure of current is ultimately the measure of how many electrons pass a given point in a given amount of time. If you have 6.241 times 10 to the 18th electrons passing a given point in one second, you have one Ampere of current flowing.
