Interconnects, some have directional indicators, why?


I'm curious as to why some interconnects are directional? Is there a physical internal difference and do they generally sound better and cost more than non-directional cables? Thanks for your interest.

Your post,
Just look at his website, then you’ll understand, why he can’t
"see the forest through the trees."

And he wants money for some of these bizzare things
has corrupted the Agon page 2 of this thread making the page difficult to read.

Please delete the post and re post the post without the last website link, or find another to post in its' place.

Thank you.

AL, (almarg)

I am guilty of saying "current flows" in an AC circuit when answering questions

regarding power branch circuits on audio forums. After reading Herman’s

responses in this thread,
https://forum.audiogon.com/discussions/directional-cables ,

I learned AC current does not flow back and forth in an AC circuit. I spent many

hours on the net trying to prove him wrong only to find Herman is correct.

For the purpose of this thread, regarding an audio signal applied to a wire cable,

AC current flow in the cable just doesn’t hold water.

IF, what is actually happening with the audio signal is that energy travels from the

source to the load, (in one direction >>>), in the form of an electromagnetic wave, in

my opinion, it then makes it easier to understand how cables can/could be directional.

(Sorry for the double space. It was the only way to make the post easier to read.)

mihorn,

Here is a response, from herman, to a post of mine to him.


If you say the AC fuse blew because there was too much current flowing

through it everybody nods in agreement even though that isn’t true. If you

say the wire in the fuse melted because it got too hot after absorbing

energy from the electromagnetic wave people look at you like you are

insane and want to argue that vibrating electrons constitute current flow.

Hi Jim (Jea48),

I recall the discussion in that 2010 thread, in which I participated. IMO the

long series of arguments between Herman and Simply_q was basically silly

and unnecessary, and to a large extent revolved around the meaning of the

word "flow."


IMO, for pretty much all practical purposes it is reasonable to speak of

current as "flowing," even if that is arguably not what physically

happens. The basic point, as you and I and most of those on both

sides of the issue agree, is that when a voltage is applied to a load via a

cable energy is transferred in just one direction. Assuming, that is, that the

load is resistive, and that reflection effects that can occur mainly at RF

frequencies due to impedance mismatches are negligible. (Which BTW,

as I indicated in my post dated 12-2-16 can under some circumstances

very conceivably cause a cable to exhibit directional characteristics

regardless of the existence or non-existence of wire directionality).


Unfortunately, though, it seems clear that agreement on one-way

transfer of energy (assuming a resistive load and negligible signal

reflections at frequencies that matter) will not lead to agreement on

whether or not wire directionality exists.
