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...

Shardone - Of course not to trust them completely but don't expect evil doing either. When I bought my car I trusted manufacturer - (profit oriented too).

Everybody is expecting conspiracy from cable manufacturers at different level. Is 9N copper or 7N silver necessary, what about zero crystal process? Is capacitance of 5pF or inductance of 40nH per foot necessary. Or complicated winding technics to lower skin effect in speaker cables. What about lowering dielectric constant by using oversized foamed teflon tubes? To many all of the above is snake oil and lamp cord from Home Depot is just fine. Whatever!
Crown on the rocks please...... No, wait, make that neat..... and a double.....
I find the theorising here, by both sides, as pointless too. I love that comment that you can't scientifically prove the existence of burn in. A true scientist realises nothing is ever proven, and only seeks to disprove his theories, not prove them. But it is not difficult to assemble evidence about burn in. It is only the practitioner that is forced to assume that tested and undisproven theories are facts.

Yet we so often have posters asking for a rationale to support claims or beliefs of others. Why they seek a rationale, when the existence of such a thing proves nothing, is what puzzles me.
