The Audioquest Pearl USB A-B Cable features high-purity Long-Grain Copper conductors and a Metal-Layer Noise-Dissipation for the most efficient dissipation of radio-frequency noise.
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 Pearl USB cable surface quality is critical because a conductor can be considered a rail-guide for both the electric fields within it and the magnetic fields outside it.
LGC has fewer oxides within the conducting material, fewer impurities, and fewer grain boundaries while creating 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, the Pearl USB A-B 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.
Hard-Cell Foam Insulation
Hard-Cell Foam (HCF) Insulation in the Pearl USB cable ensures critical signal-pair geometry. Any solid material adjacent to a conductor is also part of an imperfect circuit. Both wire insulation and circuit board materials absorb energy. They store some of this energy and then release it as distortion.
Hard-Cell Foam Insulation is similar to the Foamed-PE Audioquest use in the more affordable Bridges & Falls cables, and nitrogen-inject to create air pockets.
Because nitrogen (like air) does not absorb energy and, therefore, does not release any energy from or into the conductor, the cable can reduce distortion. In addition, the stiffness of the material allows the Pearl USB cable’s conductors to maintain a stable relationship along the cable’s full length, producing a stable impedance character and further minimizing distortion.
