0.5% Silver conductors provide much of the low-distortion advantage if pure silver at an affordable price. Silver plating is a big advantage for digital signals.
Solid conductors eliminate strand interaction, which due to electrical and magnetic interaction between strands is the single biggest source of distortion cables.
Metal-Layer Noise Dissipation System (NDS) ‘shields the shield’ reducing RFI contamination of the equipment ground plane.
