Have you considered that Cardas Audio is corporate fraud that waste employees' time on making useless cables while those slaves of double ignorance (reference to Robert Green Ingersoll and Plato) could do something useful instead?
Example of technical marketing that has no evidence whatsoever and is illegal:
"With George Cardas’ development of the Matched Propagation Conductor, which was issued US Patent 7,674,973, the Clear cable line was launched. These cables offer unprecedented transparency, accuracy, and depth of imaging."
If the cable is transparent, then it is close to the quality of cheap interconnects (its price is still tragic). But if it changes the sound in any real way, then there is something extremely unusual that is not transparent.
