The Absolute Sound 2023 High-End Audio Buyer’s Guide

“Shunyata has made some great products over the years, but the new Sigma USB may be the company’s single best achievement yet. Replace any USB cable with the Sigma USB and you’ll hear a significant improvement in soundstage openness, dynamic contrasts, and textural liquidity. Robert Harley’s reference.”


APPLICATIONS

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.


TECHNOLOGY

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.

Beyond state-of-the-art!

TAP Polarizer

‌TAP (‌‌Transverse Axial Polarizer) is a device that interacts with the electromagnetic field generated by the signal traveling along the signal cable. ‌‌TAP improves the sonic performance of the cable by modifying the behavior of the electromagnetic wave that surrounds the signal cable. In effect, the ‌‌TAP blocks longitudinal-oriented waves while passing 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.

PMZ

Shunyata Research digital cables are produced using a ‌Precision Matched Z (‌‌PMZ) concept. 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’. (Note: Z means impedance)

ArNi

‌‌ArNi® is a type of wire created by Shunyata Research designed to be the finest quality wire available for audio purposes. It begins with the highest purity of copper available – OFE C10100 or Ohno (single crystal). Then it is formed in virtual hollow tubes eliminating skin effects and eddy current distortions. A premium fluorocarbon insulation minimizes dielectric absorption and re-radiation, greatly improving resolution and clarity. In addition, the wire undergoes our proprietary KPIP™ process.

OUR ASSURANCES

RELIABILITY

Over more than 2 decades, the reliability and durability of Shunyata Research products has become a legendary attribute of the brand.  Shunyata products are completely non-reactive and run cool to the touch.  They do not hum, vibrate, buzz, or generate heat and do not require any ventilation. Despite heavy-use applications in studios, medical labs, and home environments, Shunyata Research products maintain an almost zero failure rate.

QUALITY

In an era of products that are mass-produced, Shunyata Research invests in training career craftsman who build our products by hand at our factory in Poulsbo, Washington. The exceptional fit, finish, and attention to detail has become a hallmark trait of Shunyata Research products going back to its inception in 1998. Shunyata Research has been building some of the finest power and cable products in the industry for more than twenty years. The commitment to building durable products that are designed to last a lifetime elevates our products to the top of their class.

SAFETY

Safety and quality control is job one at Shunyata Research. Before anything leaves the factory, we test each and every product thoroughly and carefully for safety and quality. This explains the long-term success of Shunyata Research products in the professional recording, medical, scientific, and consumer industries. Shunyata Research’s impeccable product safety and reliability track record for the past 23 years speaks for itself.
