Digital signal and USB cables possess extreme sensitivity to proximal noise because of the environment they are applied within. Shunyata’s new Alpha and Sigma USB cables feature a unique and expensive 100% coverage silver-braided shield, eliminating exposure to sources of near field noise radiation. Due to the high-speed nature of the digital signal, the conductors and termination junctions are perhaps the most critical aspect of any digital cable design. To address these, Caelin Gabriel uses his own proprietary design process called Precision Matched Z conductors which eliminate conductor incongruities that would otherwise distort high-speed signal transfer. This means that the tolerances of the conductor surface, dielectric extrusion, and the precision of the braided shield are held to minute variances. In order to achieve such tight tolerances, the extrusion and braiding machines must be run at one-quarter speed during the manufacturing process. The result is better performance through a reduction of cable-induced ‘signal jitter’. Both cables sport the finest CCC silver wire and FEP dielectrics to further reduce internal distortions. To finish both USB designs, custom-manufactured connectors are hand-applied using an alloy developed to eliminate junction related distortions inherent in all standard USB cable designs. The performance gain from these material refinements makes these cables the first choice for performance anywhere near its value oriented price.
The Sigma USB takes the design and performance even further by including Shunyata’s unique patent-pending TAP (Transverse Axial Polarizer), which preserves signal timing by reducing inductive field energy and improves the sonic performance of the cable by effectively modifying the behaviour of the electromagnetic wave that surrounds the signal cable.
Both cables are conditioned with Shunyata’s unique KPIP™ treatment reducing the need for burn-in and cryogenic treatment.
