AudioQuest Big Sur Cable

This cable is designed for single-ended applications, connecting devices with a 3.5mm headphone jack—such as a smartphone, tablet, or portable digital audio player—to equipment with RCA inputs, like a stereo receiver, integrated amplifier, or powered speakers.

Solid conductors eliminate strand interaction, which is a primary source of distortion in standard cables. The PSC+ material provides a smoother, purer surface that allows the audio signal to travel with less interference and greater clarity.

This design separates the ground path from the signal path, which lowers ground impedance. The result is a quieter background and a more dynamic, open soundstage compared to cables that share a common ground.

Yes, the Big Sur features a metal-layer noise dissipation system. This shielding effectively blocks radio-frequency interference, ensuring your audio signal remains clean and free from the hum or buzz often caused by nearby power cables or wireless devices.

Cold-welding creates a permanent, high-pressure connection between the wire and the plug without the use of solder. This avoids the potential for signal degradation or resistance that can occur when heating metals during the traditional soldering process.
