Cables are mysterious ~! But I think I am getting close to figuring it out. There is a great deal more to why power cords effect the sound of a component than simply "cleaning" the power or filtering out all the bad stuff.
Applying power to a conductor causes the conductor to resonate. The resonant frequency of the conductor establishes a base line for the cables sonic signature. But this is only the beginning.
As I understand it (I am not an EE) with 60Hz power there are 120 pulses per second. A pulse is the time when power can flow through the power supply transformer - when the rectified secondary voltage is higher than the stored voltage in the filter capacitor.
During the pulse, a heavy magnetic field is created and collapsed quickly within the power cord. Conductive material within reach of the magnetic field will dissipate energy through circulating currents, however some materials will attempt to store some of the magnetic field energy until the next pulse (or dissipate it as heat).
By adding material to a power cord one can change the resonant frequency of the wire, dielectric properties, and the pulse itself.
For example Taking a 10' long twisted pair of copper wire and applying more force - to twist it down to 6' in length will change the resonant frequency of the wire. Shielding that wire with tight braided copper, sticking that wire inside a tube & then filling with iron powder, fiberglass, sand, crushed aluminum, sawdust, crystals, or whatever, will again change the resonant frequency, dielectric properties and the pulse.
Each combination of materials will react differently to the magnetic field created by the pulse and presto... you have a new sonic signature in your system.
