25 YEARS IN DEVELOPMENT
Unprecedented Technological Achievement
DTCD™ DESIGN
Dynamic Instantaneous Current Delivery is critical to performance for high performance entertainment systems.
All elements in Reference XC model power cords, including the wires, contacts, dielectrics and junctions, are tested and optimized using Shunyata Research’s proprietary DTCD™ Analyzer. This optimization ensures outstanding low-frequency performance as well as dynamic contrasts akin to a live musical event.
More than any other design parameter, Shunyata Research’s ability to provide measurable dynamic instantaneous current is unparalleled.


VTX-AG CONDUCTORS
Reference XC model cables feature an 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.
CopperCONN™ CONNECTORS
Shunyata Research has developed its own line of CopperCONN™ connectors that feature solid copper contacts and true carbon-fiber head-shells (Alpha and Sigma models) that have anti-vibration qualities.
These connectors are not just beautiful; they functionally reduce micro-distortions due to the carbon fiber’s unique energy absorbing vibration reduction qualities.


KPIP™ ‘BLACKBIRD’ PROCESS
Reference XC model power cords are treated with Shunyata Research’s proprietary Kinetic Phase Inversion Process. Four days of continuous KPIP™ processing dramatically reduces burn-in time and significantly improves sonic performance, delivering a relaxed and life-like presentation.
CLASS-LEADING PERFORMANCE IN EACH PRODUCT CATEGORY
The Reference XC model power cords consistently provide superb performance across a broad spectrum of electronic brands and component types. They truly redefine the performance envelope for all types of components, including amplifiers, pre-amplifiers, phono-stages, D/A converters, disc players, and tuners.
Shunyata Research stands alone as the industry leader in patented power technologies and measurably verifiable performance.
