On all forums there's flame wars about whether it is possible to hear the difference (read: improvement) when changing cables in a system. IC's, speaker cables and power cables included.
Even though I am 57 and cannot hear a thing over 13 kHz in a hearing test, I feel it's different with music. I have no trouble detecting minor differences when changing cables, whether one or the other type. Sometimes, e.g. with IC's it can be very minor differences, and thus hard to detect.
My question is: Why do some audiophiles clearly hear the differences, while some don't?
Many explanations appear in my mind, like their equipment is insensitive to those minor changes for some reasons, or the audiophiles in question have obvious hearing deficiencies. What is yours?
Please try to keep your answer short, and please: NOT another flame war!
