AudioQuest Digital-Audio Interconnect USB Cables – Pearl
In 1982 Sony gave us “Perfect sound forever,” along with the attitude that, “it’s just digital, so all CD players sound the same.” That was disproved and qualitative differences between players became accepted truth. Next came separate transport and DAC combos, which brought with it the attitude that “all S/PDIF digital audio cables sound the same…” until that too became disproved. Now the frontier has moved once again. Is digital audio really just ones and zeros? We don’t believe so, and once you’ve had a chance to listen to Pearl USB, you won’t think so either…
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.

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.
