Description
AudioQuest Coffee Coax
Digital Audio Cable. Coffee Coax is designed for reference-level digital audio performance, featuring high-purity Solid 10% Silver conductors, a Carbon-Based 5-Layer Noise-Dissipation System, and AudioQuest’s 72V Dielectric-Bias System. Engineered to minimise jitter and reduce radio-frequency interference, Coffee Coax delivers exceptional clarity, timing precision, and low-noise signal transmission.
This product is made to order at AudioQuest headquarters in Irvine, CA. Expect moderately delayed fulfilment times. Custom lengths and terminations are available through authorised AudioQuest dealers.
Solid 10% Silver Conductors
Coffee Coax utilises solid 10% silver-plated Long-Grain Copper conductors. Because high-frequency digital signals travel primarily on the surface of the conductor, the thicker silver plating enhances Noise-Dissipation and improves signal integrity. Solid conductors also eliminate strand interaction, reducing dynamic distortion and preserving accurate digital timing.
Carbon-Based 5-Layer Noise-Dissipation
The advanced 5-Layer Noise-Dissipation System (NDS) uses alternating layers of metal and carbon-loaded synthetics to “shield the shield.” Rather than draining captured radio-frequency interference directly to component ground—where it can modulate the system’s reference plane—this design absorbs and reflects RF energy before it reaches the ground-connected layer, maintaining signal purity and reducing distortion.
72V Dielectric-Bias System (DBS)
The integrated 72V Dielectric-Bias System minimises dielectric noise by maintaining a constant electrical bias across the insulation. This linearises the dielectric behaviour, reduces time-based distortion, and significantly improves wide-bandwidth dissipation of induced RF noise.
Hard-Cell Foam Insulation
Hard-Cell Foam (HCF) insulation preserves critical signal geometry while reducing energy absorption. Nitrogen-injected air pockets minimise stored and released energy that can introduce distortion. The material’s structural stability ensures consistent impedance across the cable’s full length.
Cold-Welded, Hanging-Silver Terminations
Coffee Coax features cold-welded terminations with hanging-silver directly over pure red copper. This solder-free, high-pressure connection method eliminates solder as a potential source of distortion and enhances signal transfer reliability and conductivity.
