What if one cable is coiled or bent more than the other? Or one is an inch higher off the floor? Or if one is over wood and the other carpet? If one bends to the right and the other to the left? Well, that last one happens a lot:-)
3 feet difference and same cable? No way you will hear any difference my friend. No way. No chance. Never. Will not happen. Unless you hear strange voices in the night also?
Reasonable question actually, but near countless other things will impact your sound and this one happens to fall waaaay down the list of things to be concerned about. The condition of one spade vs. the other will have more impact.....look at that first. Oh no don't go there as life as you now know it will be over and audio anxiety will overtake you. No don't look at those spades! Just walk on by.....
Nothing is perfect. Isn't the goal to eliminate as many possible factors for higher quality sound? Why take a chance and just use 2 same length cables.
There are tons of explanations why cables, fuses, fuse direction ... SHOULD sound the same but they all sound different to me in MY system.
