Thank you.
I was about to answer: "The quality or essence of capacitance is energy storage."
Any time you have a conductor and a shield separated by a dialectric material, you have created an energy-storage system (please see link).
That is why capacitors are used in crossovers (please forgive my over-simplification): to slow down, to the point of "capture," the low frequencies, so that only the high frequencies can pass on to the tweeter.
Now that we think we know that systems with capacitance (such as loudspeaker cables) can store energy, we now must think, "Shit! How much of that 'stored energy' is the moral equivalent of 'Junk DNA' ?"
The answer is: It is junk. Or, noise.
The rapidity with which a capacitive system can discharge stray voltages ("Junk DNA") and "refresh" with the new content will, IMHO, be perceived as "having a lower noise floor."
BTW, I design cables.
BTW2: Don't expect most cable manufacturers to be willing to talk about such matters.
Have a nice wknd,
