@n80 I'm not sure what you might have learned from this thread except that there are those who do believe in cable burn-in and those who don't. I can't see how it hurts you to be open to it. If you hear no difference after time passes, you've lost nothing. If you do perceive an improvement in the openness of your sound then yippee!
One last thought. In the end, the issue is informed by your world view. If you believe that every phenomenon we experience in life is quantifiable then the intangibles will never matter to you. In my case, I've experienced too many phenomena that I would have no scientific explanation for to believe that there are not things happening in highly resolving audio systems that is beyond our ability to quantify.
Enjoy the journey!
