Shunyata Research Sigma XC Power Cable — 1.75m, C19
The Sigma XC sits in Shunyata's second tier from the top, and the XC designation means this is built specifically for high-current components — power amplifiers and power conditioners with C19 inlets that draw real current and benefit from a cable that doesn't become a bottleneck under load. The C19 IEC connector handles 20 amps natively.
The conductor is Shunyata's ArNi wire — a hollow-core VTX (Virtual Tube Geometry) design in fluoropolymer dielectric, developed to reduce the electromagnetic noise that conventional solid or stranded conductors generate and the high-frequency interference they pick up from adjacent equipment. KPIP treatment applied to the finished cable. CCI filtering built into the construction to address component-to-component interference without an external filter in the chain.
This is a significant piece of engineering for a power cable, and Shunyata publishes the measurements that justify the claim — lower noise floor, better transient response at the component it feeds. Made in Poulsbo, Washington. At 1.75 meters it reaches a conditioner from most rack positions without excess.
