From what I know (very little) from the Transparent cable literature is that through the choice of cable type, length and the addition of in-line filters that self resonance which gets into the audio band is eliminated. This minimizes distortion and peaks and valleys in the response. I also think there is a lot of trial and error going on in the design of these cables.
