When you listen to a CD do you tune in using 'audio distortion analysis' brain impregnated software? Whether there exists some proof in cloud cuckoo land as to whether or not 15 more electrons move West in cable A than cable B, and a computer prefers the bass hump of the later cable, i fail to see how any of it is relevent. Whether there exists here, on Mars, or in Gods pantry, a difference or not between two bits of wire, its wholly irrelevent when you come to sit down and listen to the music through your human ear surely? And even if you satisfy yourself with proof that all cables are identical, they are still all going to sound different, unless you eat pie and chips 365 days a year and are constructed far differently than i am.
What purpose does all of this serve? Of course, if playing with x's and y's is just a turn on, then that's a different matter. You have to pass the time doing something. But just content yourself with the fact that you are a 'human' as you choose to call yourself, and that you haven't got a ****ing clue.
