Application: The Sigmav2 NR is an ideal power cable for source equipment like CD players, DACs, tuners, and preamplifiers and it makes an excellent amplifier cable with its high-current conductors and exclusive noise reduction capabilities.
Noise is an insidious problem that originates from many sources, including audio components themselves. Shunyata Research power cords employ proprietary internal noise reduction filters that intercept noise, preventing it from propagating to other components.
NR filters are specifically engineered to be non-reactive and compatible with all power supply designs including high-power amplifiers. This multi-element, wide-bandwidth noise-reduction technology was developed by Shunyata Research’s medical division, Clear Image Scientific, to improve the performance of medical imaging systems in cardiology and neurosurgery.
"The Sigma v2 NR is quite at home in exotic audio system that have $100,000 speakers and amplifiers that are the price of luxury cars!"
"All this performance and it is still a fraction of the price of its competitors!"
Every facet of the Sigma NR power cord has been refined to deliver measurably superior Dynamic Transient Current Delivery.
DTCD™ Analysis is a technique that measures instantaneous current through low impedance electrical conductors and contacts. Shunyata Research uses it to optimize the design, specification, and construction of parts and materials to ensure maximum current delivery performance. Each part, conductor, noise circuit, and material inside the Sigma NR allows for maximum throughput of instantaneous current.
Listeners will experience earth-shaking low-frequency performance from even the highest-current amplifiers as well as dynamic contrasts unheard of outside of a live event. More than any other design parameter, Shunyata Research’s skill in eliminating resistance and maximizing peak-current delivery is unmatched.
Reference model cables feature advancement in conductor technology that combines the transient speed and definition of pure silver with the warmth, power, and body of pure copper. VTX-Ag has a core conductor of pure silver with an outer concentric conductor of high-purity OFE copper. VTX-Ag provides significant improvements in dynamics, timing precision, and low-level resolution while preserving the subtle tonal, textural, and timbral signatures that bring music to life.
Shunyata Research has developed its own line of CopperCONN™ connectors that feature solid copper contacts that have superior conductivity compared to bronze or brass contacts used in common connectors.
These connectors are not just beautiful, they functionally reduce micro-distortions. They are hermetically sealed with an electrically inert compound that protects the contacts and wires from corrosion. This also ensures that the wires cannot become loose, fray or pull out from the head shell. This guarantees a lifetime of reliable performance that does not degrade over time.
Crystalline highs and breathtaking clarity and thunderous bass capabilities make the Sigma v2 NR a winner! It is the ultimate in the Reference Line with only the mighty Omega offering better performance.
The proprietary Shunyata Research, Kinetic Phase Inversion Process was created to significantly reduce the amount of time required to burn-in cables and power conditioners. It also has a performance-enhancing effect above and beyond simply burn-in.
Four days of continuous KPIP™ processing dramatically reduces the ups and downs for new equipment and significantly improves sonic performance, delivering a relaxed and life-like presentation.
