"Do no harm!" AudioQuest has been creating high-performance audio cables for more than 30 years, guided by this simple mantra. In AQ's view, the perfect cable would be one that adds nothing no noise, no distortion to the original signal. With its Big Sur cables, AudioQuest pursues that ideal with the aid of some high-tech materials and designs. You might not expect a joined cable this thin and lightweight to deliver such great sound. So how does AudioQuest makes it happen? It's all about the details.
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.
This cable is equipped with dual RCA connectors at each end. Mini-to-mini and mini-to-RCA versions are also available.
