Digital Transmission Done Right: Shunyata Gamma S/PDIF Cable Conveys Signals with Class-Leading Timing, Dynamics, and Frequency Extension

Occasionally, products come along that represent a paradigm shift within a given category. Using 25 years worth of Shunyata Research's documented science, experience and innovation, Gamma Series cables are poised to upend price and performance axioms within the cable industry. Shunyata Research has made critical advancements in conductor science and applied them to Gamma Series cables, elevating performance far beyond expectation. Perhaps more than any other product in Shunyata Research's history, Gamma Series cables demand to be heard even when compared to cables two to three times the cost.

DRIVEN BY SCIENCE

Gamma signal and digital cables are made with the finest conductors available. Single-crystal, continuous cast Ohno copper is an ultra-pure conductor normally found in far more expensive cables. Ohno conductors are extruded using Shunyata Research's exclusive PMZ (Precision Matched Impedance) process. This extrusion method tightens the tolerances of the conductor surfaces, dielectric extrusions, and the precision of the braided shield. All are held to minute tolerances. The extrusion and braiding machines must be run at one-quarter speed during the manufacturing process. Finally, all Gamma cables are conditioned for 4 days using advanced Kinetic Phase Inversion Process (KPIP v2™).

PURITY IN TONE. DYNAMIC BY NATURE.

If choosing a single word to encapsulate the sound of a Gamma Series cable system, it would be coherence. Every aspect of Gamma cable system performance simply flows with the ease and clarity of a single voice. Textural and tonal nuance is balanced perfectly against Gamma's explosive, dynamic nature. Gamma cable systems never sound forward, bright, aggressive or edgy. However, what truly separates Gamma cables from all others, regardless of cost, is their self-effacing alacrity, timing accuracy, dynamic punch and frequency extension. Most pure-copper cables, even expensive models, may sound warm, rich, and full bodied at the expense of accurate timing, dynamics and frequency extension. Gamma cables sound very natural, but are surprisingly agile, athletic and entirely unforced with regard to expressing frequency extension, timing, weight and authority in the low octaves. Gamma cables do all of this without calling attention to themselves, allowing the purity of the sound to take center stage.

TECHNOLOGY

Shunyata Research produces select cables 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. (Note: Z means impedance)

Ohno wire, also called ‌PCOCC was invented in 1986 by professor Atsumi ‌Ohno of the Chiba Institute of Technology in Japan. Copper wire is created by an extrusion process that pulls a rod of cold copper through a small orifice which creates multiple crystalline boundaries. By contrast, ‌‌Ohno wire is made by a process using heated molds that cast a wire to form a single crystalline structure. ‌‌Ohno wire is well known for its exceptionally pure, grain-free sonic qualities.

KPIP v2™ PROCESSING
Shunyata Research's proprietary Kinetic Phase Inversion Process includes four days of continuous KPIP v2™ processing which refines conductor metals at a molecular level. This dramatically reduces burn-in time and significantly improves sonic performance, delivering a relaxed and life-like presentation. When compared to the original process, KPIP v2™ represents a dramatic performance upgrade on par with a component-level upgrade.
