AudioQuest Big Sur Interconnect Cable
The AudioQuest Big Sur cable is a landmark in high-quality, affordable analog interconnects, designed to let the natural beauty of your music flow through. It features Solid Perfect-Surface Copper+ (PSC+) conductors for a low-distortion signal path, and Foamed-Polyethylene insulation to minimize energy absorption. The Metal-Layer Noise-Dissipation System (NDS) prevents captured RF interference from affecting the ground reference, while the Double-Balanced Asymmetrical Geometry offers a lower impedance on the ground for a richer, more dynamic experience. It is finished with cold-welded, gold-plated 'Purple-Copper' RCA plugs for a solder-free, distortion-free connection.

Know before you buy
The PSC+ conductors feature an ultra-smooth surface that minimizes graininess and harshness in the audio signal. This results in a cleaner, more natural sound compared to standard copper cables.
The NDS acts as a shield that prevents radio frequency interference from reaching the cable's ground reference. By blocking this noise, it ensures your music remains free from background hums or electronic interference.
Solder is often a point of signal degradation and resistance. Cold-welding creates a high-pressure connection between the plug and the conductor, maintaining signal integrity and preventing the distortion that can occur with heated solder joints.
This design provides a lower impedance path for the ground, which helps the cable deliver a more dynamic and richer sound. It effectively separates the ground and signal paths to ensure a cleaner, more stable audio transmission.
The 0.6-meter length is ideal for connecting components that are stacked or placed directly next to each other, such as a DAC to an amplifier. If your equipment is further apart, you may need a longer cable to avoid tension on the connectors.
