It is not quite as black and white as this but this seems to be a rule of thumb. At any rate, I am amazed you are finding a difference.

On the surface variations between cables of their LCR values seems to make
sense until one realizes that the small values involved with most ICs [especially very short ones] would not have any effect on the audio band unless being fed from very high source impedances etc.
As I have previously mentioned, I seem to have perceived differences in cable sound that compare in magnitude to those i perceive when making fine
adjustments to a passive filter with component values designed to work
in the audio band..
When one considers the different materials and configurations cables are made
from it would seem logical that a signal should be affected in some minute
way by such variations but I as far as I know I do not believe any measurements have shown any concrete results as to what may have changed to actually create an audible difference.
There are many loooong and heated threads over at :
www.diyaudio.com that discuss these matters.
And on the subject of insanity.
At the moment I am preferring the economy maplin ICs over the siltech silver in my portable rig.
But I also prefer some of what the the silver do over the copper sooo
as I use a passive eq network to tune my ETYs sound , I could tweak it to
adjust for the shortcomings [to my ear] of the silver thus eliminate the shortcoming of using the copper.................

Insane.
