Diamond Coax
Digital Audio Cable
Diamond Coax features extreme-purity Perfect-Surface Silver (PSS) conductors and a Carbon-Based 6-Layer Noise-Dissipation system for the most efficient dissipation of radio-frequency noise.
Key Features & Technology Explained
Solid Conductors
Solid conductors prevent strand-interaction, a major source of dynamic distortion in cables.
Perfect-Surface Silver Metal
AudioQuest's highest-quality metal. Perfect-Surface Silver (PSS) minimises distortion caused by grain boundaries and maximises linear RF Noise-Dissipation.
Carbon-Based 6-Layer Noise-Dissipation
Alternating layers of metal and carbon-loaded synthetics "shield the shield," absorbing and reflecting most RF energy before it reaches the layer attached to ground.
72v DBS Technology
72v Dielectric-Bias System (DBS) saturates and polarises insulation, allowing clear, dynamic sound against a quiet “black” background.
Hard-Cell Foam Insulation
Hard-Cell Foam's high air content minimises energy absorption for clearer sound.
Direction Controlled
All conductors controlled for RF-noise directionality.
Solid Perfect-Surface Silver (PSS) Conductors
Solid conductors prevent electrical and magnetic strand-interaction. PSS Solid-Silver minimises distortion caused by grain boundaries and maximises linear RF Noise-Dissipation.
Carbon-Based 6-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) w/ RF Trap
Insulation is also a dielectric that can act like a shunt-filter. Biasing minimises dielectric-noise and linearises 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 minimising distortion.
