Directional interconnect cables


I see several big-name interconnect vendors mark directional arrows on the outer jacket of the cables.

How is it that a wire can be directional? It's a simple electrical conductor, how is it possible for it to be directional, to sound "better" when connected in one direction vs. the other? This does not make sense to me, perhaps someone here can explain how this can possibly be so...

Redkiwi, you might find the theorising pointless, but so is making completely false statements like "A true scientist realises nothing is ever proven".

Science can and does prove things by postulating theories, and then repeatedly testing and measuring to try to disprove the theory. If the tests show that the thoery holds, it becomes 'law', if not it is disproven. Such scientific 'proof' is legitimate in a court of law, but apparently not on Audiogon!

There are some things that can't be disproved because science does not yet have the capability or theories to test them accurately, as Richard Dawkins' "celestial teapot" shows; I could say that there is a teapot orbiting the Earth, which at this point in time couldn't be disproved with current astronomical equipment. Does that mean it's true? No, but "teapot-believers" would use that as evidence the teapot must exist.

Science disproves burn in for a simple reason; science uses 'before and after' measurements of various parameters of the cable. If these stay the same after the burn-in period, then the electrical properties of the cable are unchanged and burn-in is not supported. Whether you perceive a change with your (subjective) sense of hearing is another matter.

You have to remember that human ears are an amazingly sensitive piece of equipment, but the way we hear is subject to many other factors; the shape of the outer ear, wax deposits, nasal congestion, and even our mood can change the way we perceive sound.

Despite my science education, I do beleive I can hear differences between IC's and speaker cables, although I haven't noticed any change due to burn-in. But these are just my observations on my system with my ears, not proof.
Here's some food for thought. A while back I demo'd some Monster cable Z series balanced IC's while waiting for my Oracle V2.2 upgraded IC's to be returned (my dealer loaned them to me). $4600pair IC's vs $200pair IC's....wow, they were close in presentation!
Then your definition of the word proof is different from mine. As a scientist I do not accept that science ever proves anything. But your PHD may have come from a different university than mine and so I am cool with the way you see things, but not so cool with you calling my statements false. So far I have not attacked you. What interests me is why you felt the need to attack me. As for your teapot analogy, you missed out the bit where we thought we saw a teapot.
Oh my God - Are you ALL guys SCIENTISTS???
One vodka on ice for me, pleeeeease (always helps in scientific discussions).
On the second thought - make it double.

Carl109 - There is a huge sound difference between ICs and speaker cables.
I tried once speaker cable between pre-amp and power-amp and it sounded non-interesting. No highs, poor definition and a lot of static.
This thread is priceless, lol. Another round on me... but looks like some here are already wasted.

So what do you do when there are no pretty little arrows? Are those cables "directionless"? ;)
