Audioquest Big Sur - RCA to RCA Cable 1 Meter Experience superior audio clarity with the Audioquest Big Sur RCA to RCA cable, designed to deliver clean, dynamic sound for your home theatre or audio system. Key Features Solid Perfect-Surface Copper+ (PSC+) Conductors: Ultra-pure, low-distortion copper with a smooth surface for focused, clear sound. Foamed-Polyethylene Insulation: Air-filled insulation reduces energy loss and distortion for a natural audio experience. Metal-Layer Noise-Dissipation System (NDS): Prevents radio frequency interference (RFI) from affecting your equipment’s ground reference. Asymmetrical Double-Balanced Geometry: Separates ground and shield for lower impedance and quieter, richer sound. Cold-Welded Gold-Plated Pure Purple Copper RCA Plugs: Solder-free connection with low-distortion metal for cleaner, clearer audio. Product Description The Big Sur cable features Solid Perfect-Surface Copper+ conductors, manufactured using proprietary metal-processing technology to maintain an exceptionally smooth and pure copper surface. This results in a low-distortion conductor that outperforms traditional copper cables. Foamed-Polyethylene insulation surrounds both conductors, utilising air to minimise energy absorption and distortion, preserving the integrity of your audio signal. Audioquest’s Metal-Layer Noise-Dissipation System (NDS) provides 100% shield coverage and effectively reduces RFI interference, ensuring a cleaner signal path. The asymmetrical double-balanced geometry is purpose-designed for single-ended applications, offering lower ground impedance and separating the ground from the shield for improved performance. The cable is terminated with cold-welded, gold-plated pure purple copper RCA plugs. These solder-free connectors reduce distortion and provide a more transparent connection compared to standard nickel-plated or OFHC plugs.
