No cable have a sound of their own.
Guess why ?
A clue : they are parts of a whole called sound by acoustics...
The string of a violin had no sound of his own, it depend of many parameters as his diameter, composition, tension, etc ...
An audio cable is a link in a vibrating sound source giving to it or adding to it his own changing specific parameters... Then a specific sound ... because the human ears is very sensible to change qualities .... A field well investigated now... See video by Milind Kunchur in my new thread...
