AudioQuest Big Sur Interconnect Cable

This cable is designed to connect devices with a 3.5mm headphone output—such as a smartphone, tablet, or portable digital audio player—to equipment with RCA inputs, like a stereo receiver, integrated amplifier, or powered speakers.

The Solid Perfect-Surface Copper+ (PSC+) conductors are designed to minimize distortion caused by strand interaction, which is common in standard cables. By using a single, high-purity solid conductor, the signal path is cleaner and more consistent.

Cold-welding eliminates the use of solder, which can often act as a point of resistance or impurity in the signal path. This method creates a direct, high-pressure connection between the wire and the plug for a more reliable and transparent signal transfer.

Yes, the cable features a Metal-Layer Noise-Dissipation system that acts as a shield against high-frequency interference. This helps prevent external noise from entering your audio signal, resulting in a quieter background and clearer music reproduction.

This geometry separates the ground path from the signal path, allowing for a lower-impedance ground and a more dynamic, open sound. It is specifically engineered to provide a richer, more balanced performance compared to standard single-ended cable designs.
