High-Definition Digital Audio Cable

Pearl USB features high-purity Long-Grain Copper conductors and a Metal-Layer Noise-Dissipation 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.

Long-Grain Copper Metal

High-purity Long-Grain Copper (LGC) conductors minimise distortion caused by grain boundaries.

Metal-Layer Noise-Dissipation

Metal-Layer Noise-Dissipation shields noise effectively, absorbing and reflecting most RFI before it reaches the ground layer.

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 Long-Grain Copper (LGC) Conductors

Solid Long-Grain Copper (LGC) allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. Solid conductors prevent strand interaction, a major source of distortion. The surface quality is critical because a conductor can be considered as a rail-guide for both the electric fields within a conductor, and for the magnetic fields outside the conductor. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance.


Metal-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. 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. Noise-Dissipation "shields 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 minimising distortion.


Direction-Controlled Conductors

All drawn metal strands or conductors have a non-symmetrical, and therefore directional, grain structure. AudioQuest controls the resulting RF impedance variation so that noise is drained away from where it will cause distortion. The correct direction is determined by listening to every batch of metal conductors used in every AudioQuest audio cable. When applicable, arrows are clearly marked on the connectors to ensure superior sound quality. For most models of AQ cable, the arrows not only indicate the direction that optimises metal-directionality as part of Noise-Dissipation, but also indicates non-symmetrical attachment of shield and GND in order to optimise full-system performance. A fundamental aspect of AudioQuest's multifaceted Noise-Dissipation technology, Direction-Controlled Conductors ensure induced noise is dissipated and drained properly.
