Solid conductors prevent strand-interaction, a major source of dynamic distortion in cables. ^^ To an even greater extent than LGC, higher-purity Perfect-Surface Copper (PSC) conductors minimize distortion caused by grain boundaries. ^^ Metal-Layer Noise-Dissipation shields noise effectively, absorbing and reflecting most RFI before it reaches the ground layer. ^^ Foamed-Polyethylene's high air content minimizes energy absorption for clearer sound. ^^ All conductors controlled for RF-noise directionality.
