Speaker cable arrows???

@jea48 Jim, I really do appreciate your thoughtful answer. I'm not the smartest guy in the world (you heard it here first) but I am pretty well educated in math, physics, chemistry and metallurgy. Every explanation I have heard of signal directionality in a low voltage passive cable has been marketing fluff. I'll use this for example, from Nordost:

When cables are manufactured they do not have any directionality. However, as they break in, they acquire directionality.

But wait, it gets better:

Although the cable signal is an alternating current, small impurities in the conductor act as diodes allowing signal flow to be better in one direction over time. This effect is also called quantum tunneling, which has been observed in experiments over 25 years ago. Regardless of the purity of the metal used, there are still diode effects in all conductors. In addition, the insulation material will change when it is subjected to an electrical field.

[sound of me laughing hysterically] Quantum tunnelling. It's a real thing, but it's quantum mechanics and the theoretical potential barrier only occurs at the subatomic level. Doesn't affect wave propagation though normal materials, at least at temperatures and pressures you and I can survive at.

I'm not trying to convince you and I know I shouldn't have responded to your or anyone's post about this. If you hear a difference I'm happy for you. I mean that seriously. I don't, and the math doesn't support the outcome you propose. But that doesn't affect your listening pleasure.

OK all, I'm officially tired of this thread. I would like to thank jea48 for his gentlemanly responses and his attitude. Jeff, I really wish I could understand which side of a question you are arguing after reading your posts. But I guess that's what keeps this fun and interesting.

You guys are hilarious. Speaker cable directionality - it IS possible to intentionally design and construct a "directional cable", but not as a passive device. Think about it: does your directional cable possess differing impedance in either direction? If so, how is that accomplished? (hint - it's not).

Then there is the issue of signal to your speakers being AC, not DC as is commonly thought. Again, please explain to me exactly how you can create or maintain directionality in an AC line?

The signal energy travels down the cables in one direction >>>> from the source to the load, (amp to speakers), in the form of an electromagnetic wave.

@jea48 dude, you really might want to take a remedial physics class. I will ask again: please explain to me exactly how to make a passive conductive cable with unequal impedance.

@jea48 What's the point of linking back to this very thread? I have asked you twice to please explain to me how signal directionality happens or is possible in a passive cable. All you have done is ask me to re-read the yours and others opinions on the subject. As one of my Geology professors explained to me many years ago "if you can't explain it to someone else then you don't understand it yourself."
