There used to be a working link I've used in past discussions on cable directionality and it's not coming up anymore.
(
http://www.tubemastering.com/philtaylor.pdf )It had to do with Pink Floyd and the building of a studio on the Astoria (David Gilmore's house boat), a boat they used to record on. In between sessions, they swapped cable directions and easily heard the differences, preferring one way over the other.
The best I can do right now was to find an article that doesn't go into it in such depth but speaks to the differences in cabling that can be heard.

There's also this from Tony Farinella who makes the cables that David Gilmore uses:
http://sparebricks.fika.org/sbzine28/ggg.html There is a section where he discusses cable directionality.
Let's see... another non working link to TapeOp about the house boat and cable directionality....can't find anything else for the moment.
All the best,
