Solid Perfect-Surface Copper+ (PSC+) conductors
One of the most important materials that goes into an audio cable is the metal used for its conductors — the parts of the cable that actually carry the signal. Big Sur cables feature conductors made from a material AudioQuest calls "Perfect-Surface Copper+." PSC+ starts with ultra-pure copper, formed into solid (not stranded) conductors with an astonishingly smooth surface. The end result: clean, low-distortion signal transfer for transparent sound.
Advanced cable geometry
While many cables use a single path for both the ground and shield, AudioQuest uses a design they call "double-balanced asymmetrical geometry." This design separates the ground and shield paths for clean, quiet performance.
Cold-welded "Purple Copper" connectors
Big Sur's connectors are cold-welded, rather than soldered, which eliminates a common source of distortion found in many audio cables. They're made from high-purity, gold-plated "Purple Copper," which outperforms more common connector materials where it counts — in the listening room.
