err, i'm a graduate of the Audioholic "it don't make a difference" school of thought
i know there will be no audible difference. i just like the colors/finishes of the cords. i just thought it was time to fix up my wire spaghetti (black color at that)
i mean, it's not like i thought that the red power cord would make my music "Warmer" and the blue power cord "cooler"
