AudioQuest Cinnamon Digital Coax

Cinnamon Coax features high-purity Solid 1.25% Silver conductors and a Metal-Layer Noise-Dissipation system for the most efficient dissipation of radio-frequency noise.

Core Technical Features

• Solid 1.25% Silver Conductors: While the base of the wire is high-purity copper, it is plated with a layer of solid silver. Since high-frequency digital signals travel almost entirely on the surface of a conductor (the "skin effect"), this allows the cable to perform similarly to a solid-silver cable at a much lower cost.

• Hard-Cell Foam (HCF) Insulation: The cable uses nitrogen-injected foam to create air pockets. Air is the ideal insulator because it doesn't absorb or release energy, which helps maintain the cable's critical 75-ohm impedance and prevents signal distortion.
• Metal-Layer Noise-Dissipation System (NDS): This system "shields the shield," absorbing and reflecting radio-frequency interference (RFI) before it can reach the ground plane of your equipment.
• Cold-Welded Terminations: The gold-plated RCA plugs are attached using a high-pressure process rather than solder. Solder is often a source of distortion because it introduces an extra layer of different metal into the signal path.
