AudioQuest Big Sur Stereo Interconnect Cable

Perfect-Surface Copper+ (PSC+) features an ultra-smooth surface that minimizes the graininess and distortion often found in standard copper cables. This results in a cleaner, more transparent sound profile.

The arrow indicates the preferred direction of the signal flow. Because the cable's shielding and geometry are optimized for a specific path, you should connect the end with the arrow toward your receiving component, such as an amplifier or powered speaker.

The NDS uses layers of metal to shield the internal conductors from radio-frequency interference. This prevents external noise from contaminating your audio signal, ensuring a quieter background and better clarity.

Cold-welding is a process that joins the cable to the plug without using solder. By avoiding solder, which can be a point of signal degradation, the connection remains more pure and less prone to distortion.

While the Big Sur features a durable braided jacket, it remains reasonably flexible for standard home audio setups. However, you should avoid bending it at sharp angles to maintain the integrity of the internal conductors.

This design separates the ground path from the signal path, which helps reduce noise and interference. It allows the cable to provide a cleaner, more stable performance compared to standard unbalanced designs.
