Shunyata Research Sigma USB Cable
The Sigma is the penultimate USB cable in the Shunyata range and is has come about after long period of extensive research and development from Caelin Gabriel and his team.
It comes in a standard length of 1.5, but it can be ordered in increments of 25cm, each increment is £130.00, so it is £520 for an extra metre.
The Sigma uses a huge array of technology developed by Shunyata and it is a superb cable. Just like the Omega above it the Sigma is not inexpensive at £2500 and as such it will only be typically used in larger systems, but when used between 2 more modest components it can extract so much information and deliver better performance than lesser USB cables, it will really show you want your electronics are cable of doing
SR USB Cable— There are many problems with off-the-shelf USB cables including poor quality conductors and dielectrics and insufficient shielding. Conventional cables induce high amounts of signal jitter and phase noise degrading sonic performance.
The SR-USB-Cable is an exclusive Shunyata Research product that was designed to achieve the ultimate levels of performance without regard to production cost. It starts with our highest grade of ArNi® wire featuring pure OHNO copper in a VTX™ geometry with fluorocarbon dielectrics. The power wiring is a completely different type of conductor designed specifically for DC power transfer minimizing any signal transmission interference. Massive silver-plated copper braided shields protect the delicate signals from external RFI/EMI.
SR-USB — There are very few great quality USB connectors so we created our own. It features an easy to grip, large diameter head-shell that accepts large gauge wiring. It has an exceptional strain-relief system that ensures longterm reliability even with heavy usage. The contacts are made from high conductivity gold-plated copper assuring minimal signal junction impedance.
Transverse Axial Polarizer is a device that interacts with the electromagnetic field generated by the signal traveling along the signal cable. TAP affects the behavior of the electromagnetic wave that surrounds the signal cable. In effect, the TAP blocks longitudinal-oriented waves while allowing transverse-oriented waves. The effect in sonic terms is like using polarized sunglasses to reduce reflected sunlight. Correcting polarization micro-distortion reduces what some call sonic glare.
— Patent Pending
PMZ — Shunyata Research digital cables are produced using a Precision Matched Impedance cable geometry. This means that tolerances of the conductor surface, dielectric extrusion, and the precision of the braided shield are held to minute variances. To achieve these 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.
(Z definition = impedance)
ArNi® wire was designed by Shunyata Research to be the finest quality wire available. It begins with the highest purity of copper and silver metals available, including Ohno (single crystal), PCOCC silver and OFE C0101 conductors. Fluorocarbon dielectrics, usually only found in aerospace applications that have exceptional electrical characteristics including extremely low dielectric absorption, high dielectric strength and superb heat resistance. When used in digital wiring it significantly reduces transient energy storage and release which affects phase noise performance.
— And finally every cable undergoes our proprietary KPIP™ process.
Kinetic Phase Inversion Processing
Kinetic Phase Inversion Processing was developed by Caelin Gabriel after years of research into the underlying causes of various effects such as burn-in, wire directionality and the effects of cryogenic treatment. He discovered that there was an underlying core principle that burn-in and cryogenics only partially addressed. Once the governing principle was understood it became possible to create a processor that reduces the need for long burn-in periods and eliminates the effects of cryogenic treatment. Four-days of continuous KPIP™ processing dramatically reduces the sonic ups and downs associated with burn-in, delivering a relaxed and natural presentation.
