I just listen to what my ears tell me - and my cables do reveal more detail. I certainly can't hear, for example, the peddles of a piano moving on any of my ipods, or my partners mini hifi set up, or lesser cables in my system. Whether you want to is a matter of personal taste. Whether my set-up is everyones idea of what the original should sound like is another matter again.

better positioning of the components - possibly ?
better mounting of the components - probably not
