Just a quick question, can any of you hear the 16kHz sound that comes from tube tv's? Or the sound of the capacitor charging in a flash camera? If not, then I'm not surprised you can't hear any differences in wire.
How about the memory.. I know this a gross example, but do you remember the fire alarm in grade school? When you think about it, don'tyou remember what it sounded like? What about when you walk outside in the morning to go to work, you can hear it in your head when you think about it, right?
Now, how about this. If you think about it, can't you "hear" in your mind the difference in the sound of running water in your bathroom, kitchen, bath tub, shower, and washing machine? All running water, so if there's no memory of auditory details, why did you just hear all of those different sounds in your head? What about the sound of your car engine, versus the sound of your wife's car? Do you need to look outside to know which car she is taking down the road? No? Because you remember what your car sounds like?
So why is it so hard to believe that type of memory is possible with smaller details?
Edit: Besides, guys I don't know what kind of stereos you all have, but I have a Pioneer receiver that's like 300 watts and a pair of Bose 501's. If your stereo isn't as good as that I can see why you can't tell any differences in wire.
