Using Cables as Tone Controls

[Smokey]

Great in theory but in today's real world, Cables are now a Component and can be worked with as such.

Premisses of cable has not changed over a century. Although we have better material to build a cable, but functionality of cable has not changed. The concept here is that best cables are "soundless". Treated any other way and we are led into slippery slope...such as using an extension cord for speaker cable

Smokey, my question for you is how do you know which cable has the right sound as it was intended to be at the time of the recording.

To hear the intended sound of recording, your cable should be "soundless". Since every record sound differenet and your system might have its own signature, then the best approach to cable would be to choose the ones that are most transparent. And as it was said before, that can be better achived objectively rather than subjectively.
