Key Technologies
Solid 5% 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.
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 Carbon Coax cable used for?
It's a premium digital coaxial audio cable designed to transmit digital audio signals with minimal interference, delivering cleaner, more accurate sound between components.
Q What makes the conductor design in the Carbon Coax special?
It uses solid 5% silver conductors over long-grain copper, which reduces strand interaction — a common source of distortion in cheaper cables with multiple thin strands.
Q How does the cable protect against radio-frequency interference?
It uses a carbon-based 5-layer noise-dissipation system that "shields the shield," absorbing and reflecting RF interference through directional draining before it can reach the ground plane and degrade the signal.
Q Why does the insulation matter for signal quality?
The cable uses nitrogen-injected Hard-Cell Foam insulation, which keeps the conductor geometry stable and reduces the amount of signal energy absorbed by the insulation itself.
Q What's the price range and availability for this cable?
Pricing starts at $449.95 depending on length (0.75m to 5m options), with shipment across Canada within 1-3 business days, plus professional installation available in the Ontario GTA, Hamilton, and Edmonton areas.
