Key Technologies
Solid 10% Silver Conductors
Solid conductors minimize the harmful effects of both electrical and magnetic strand-to-strand interaction. For digital cables, whose signals are of such high frequency that they travel almost exclusively on the surface of the conductor, increasingly thick layers of silver plating are applied to AudioQuest’s Long-Grain Copper (LGC) conductors to further improve Noise-Dissipation. Placing the superior metal on the outside of the conductor produces the greatest benefit on overall performance—a superbly cost-effective way to maximize a digital cable.
Carbon-Based 5-Layer Noise-Dissipation
It's easy to accomplish 100% shield coverage. Preventing captured Radio Frequency Interference (RFI) from modulating the equipment's ground reference requires AQ's Noise-Dissipation System (NDS). Traditional shield systems typically absorb and then drain noise/RF energy to component ground, modulating and distorting the critical "reference" ground plane, which in turn causes a distortion of the signal. NDS's alternating layers of metal and carbon-loaded synthetics "shield the shield," absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground.
72v Dielectric-Bias System (DBS)
Insulation is also a dielectric that can act like a shunt-filter. Biasing minimizes dielectric-noise and linearizes the filter, significantly improving wide-bandwidth dissipation of induced RF noise.
Hard-Cell Foam Insulation
Hard-Cell Foam (HCF) Insulation ensures critical signal-pair geometry. Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy. Some of this energy is stored and then released as distortion. Hard-Cell Foam Insulation is similar to the Foamed-PE used in our more affordable Bridges & Falls cables, and is nitrogen-injected to create air pockets. Because nitrogen (like air) does not absorb energy and therefore does not release any energy from or into the conductor, distortion is reduced. In addition, the stiffness of the material allows the cable's conductors to maintain a stable relationship along the cable's full length, producing a stable impedance character and further minimizing distortion.

Q What is the Audioquest Coffee Coax cable used for?
It's a high-end digital coaxial audio cable built to carry digital audio signals with minimal noise and distortion between components.
Q What sets the Coffee's conductors apart from lower-tier cables?
It uses solid 10% silver conductors — double the silver content of Audioquest's Carbon model — which further reduces strand-to-strand interaction and electrical distortion.
Q What is the Dielectric-Bias System (DBS), and what does it do?
DBS is a 72-volt system that saturates the cable's insulation, which helps produce clearer audio with less background noise — a feature not found on the lower-tier Carbon cable.
Q How does the Coffee cable shield against interference?
It uses a carbon-based 5-layer noise-dissipation system that alternates metal and carbon-loaded synthetic layers to block radio-frequency interference from degrading the signal.
Q What materials make up the cable's construction?
It features a silver-plated braid shield, Hard-Cell Foam insulation for stable conductor geometry, a brown-on-black nylon braid jacket, and cold-welded silver terminations over pure copper.
