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.....
