AudioQuest Big Sur Interconnect Cable
Best high-fidelity upgrade for audiophiles connecting portable devices to home systems.
The AudioQuest Big Sur cable is designed to be a landmark in affordable analog interconnects for portable devices and other audio gear. It features Solid Perfect-Surface Copper+ Conductors (PSC+) for superior signal transfer, along with Foamed-Polyethylene insulation to minimize energy absorption and distortion. The Metal-Layer Noise-Dissipation System (NDS) effectively prevents captured radio frequency interference from modulating the equipment's ground reference. Its Double-Balanced Asymmetrical Geometry provides a lower impedance on the ground for a richer, more dynamic experience. The cable is finished with cold-welded, gold-plated Purple-Copper plugs, ensuring a solder-free connection that reduces distortion.

Know before you buy
Perfect-Surface Copper+ (PSC+) features a smoother, purer surface than standard copper. This reduces graininess and distortion in the signal path, resulting in a cleaner and more detailed audio presentation.
The NDS shielding prevents radio frequency interference from reaching your equipment's ground reference. By blocking this noise, it ensures your music remains clear and free from the background hum or static often caused by external electronic interference.
Solder is often a weak point in signal transmission because it is a different metal than the wire and plug. Cold-welding creates a high-pressure, solder-free connection that maintains the integrity of the signal path for lower distortion.
This geometry uses separate conductors for the positive and negative signals, while providing a lower impedance path for the ground. The result is a more dynamic, rich, and balanced sound compared to cables that share a ground and return path.
At 16 meters, this cable is designed for longer runs where signal integrity is critical. Its high-quality shielding and conductor materials are specifically chosen to maintain performance over this distance without significant signal loss.
Standard insulation can absorb energy and release it back into the signal, causing distortion. Foamed-Polyethylene contains nitrogen bubbles that minimize this energy absorption, keeping the timing and clarity of your audio intact.
