In 1982, Sony presented us with “perfect sound forever,” along with the notion that “it’s just digital, so all CD players sound the same.” This was refuted, and qualitative differences between players were accepted as truth. Then came separate transport and DAC combos, with the idea that “all S/PDIF digital audio cables sound the same…” until that too was disproven. Now, the frontier has once again evolved. Is digital audio truly just ones and zeros? We don’t believe so, and once you’ve had the opportunity to listen to the Pearl USB, you won’t think so either…

Available Lengths: 0.75m, 1.5m, 3m, 5m

  • HARD-CELL FOAM (HCF) INSULATION:Hard-Cell Foam (HCF) insulation is employed to ensure critical signal-pair geometry. This type of insulation, similar to the Foamed-PE used in more affordable cables, is nitrogen-injected to create air pockets. Nitrogen, like air, does not absorb energy and, therefore, does not contribute to the release of energy into the conductor. This reduction in energy release helps minimize distortion. Additionally, the stiffness of the material plays a role in allowing the cable’s conductors to maintain a stable relationship along its entire length. This characteristic produces a stable impedance and further aids in minimizing distortion.


    To minimize interference and ensure a cleaner signal transmission, all conductors in the cable are meticulously controlled for radiofrequency (RF) noise directionality. This directional control contributes to an overall reduction in noise, enhancing the purity of the transmitted signal.


    The cable utilizes Solid Long-Grain Copper (LGC) conductors, known for delivering a smoother and clearer sound compared to cables using regular Oxygen-Free High-Conductivity (OFHC) copper. Solid conductors in the LGC configuration prevent strand interaction, a significant source of distortion. The surface quality of these conductors is crucial as they act as rail-guides for both electric and magnetic fields. LGC boasts fewer oxides, impurities, and grain boundaries within the conducting material, ultimately resulting in definitively better performance.
