AudioQuest Digital Coax cables are designed to minimize distortion across an extremely wide bandwidth. For many applications, the speed of digital communication is important. Speed is critical not because of how-much how-fast, but because time relationships within a digital stream are critical to the reconstruction of the analog waveform that brings information, music and joy to our ears.

SOLID PERFECT-SURFACE SILVER (PSS) CONDUCTORS:
Perfect-Surface Technology applied to extreme-purity silver provides unprecedented clarity and dynamic contrast. Perfect-Surface Silver (PSS) is AudioQuest's highest-quality metal. Solid conductors prevent strand interaction, a major source of cable distortion. Extremely high-purity Perfect-Surface Silver minimizes distortion caused by the grain boundaries that exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.
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.
CARBON-BASED 7-LAYER NOISE-DISSIPATION SYSTEM (NDS), 2 X EMI ABSORPTION:
100% shield coverage is easy. Preventing captured RF Interference from modulating the equipment’s ground reference requires AQ’s Noise-Dissipation System. Metal and Carbon-Loaded synthetics prevent most RFI from reaching the equipment’s ground plane.
DIELECTRIC-BIAS SYSTEM WITH RADIO FREQUENCY TRAP:
All insulation between two or more conductors is also a dielectric whose properties will affect the integrity of the signal. When the dielectric is unbiased, dielectric-involvement (absorption and non-linear release of energy) causes different amounts of time delay (phase shift) for different frequencies and energy levels, which is a real problem for very time-sensitive multi-octave audio. The inclusion of an RF Trap (developed for AudioQuest’s Niagara Series of power products), ensures that radio frequency noise will not be induced into the signal conductors from the DBS field elements.
