Product details:

Perfect-Surface Copper+ has an astonishingly smooth and pure surface. Proprietary metal-processing technology protects the wire's surface at every stage of drawing and fabrication. Big Sur uses air-filled Foamed-Polyethylene Insulation on both conductors because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile. Noise-Dissipation System prevents a significant amount of RFI from reaching the equipment's ground plane. Asymmetrical Double-Balanced Geometry offers a relatively lower impedance on the ground for a richer and more dynamic experience. Cold-welded, gold-plated pure purple copper terminatins allow for a connection devoid of solder, which is a common source of distortion.
