{"product_id":"shy-sigma-xc-c19","title":"Shunyata Research Sigma XC Power Cable — 1.75m, C19","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe 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.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe 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.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThis 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.\u003cbr\u003e\u003c\/p\u003e\n\u003ch5 class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\n\u003cbr\u003e\u003cspan style=\"color: rgb(253, 183, 22);\"\u003e$2,195 MSRP\u003c\/span\u003e\n\u003c\/h5\u003e","brand":"Shunyata Research","offers":[{"title":"Default Title","offer_id":47682895151241,"sku":"SIGMA XC C19","price":3250.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/4557\/0185\/files\/SigmaxcC19.png?v=1785014994","url":"https:\/\/echohifi.com\/products\/shy-sigma-xc-c19","provider":"Echo Audio","version":"1.0","type":"link"}
