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...

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"? ;)
Macallan or Lagavulin for me, but I am fussy about which ones - though I am sure its all in my head and a blind man woldn't be able to tell the difference.
