Shunyata Research Sigma X-QR 1.75m C-15 With QR/BB Technology. Premium

Overview

The Shunyata Research Sigma X-QR is the answer for audiophiles who want to elevate their system to a genuinely higher level. True to Shunyata’s tradition of migrating its most profound patented technologies into more accessible products, the Sigma X-QR brings the extraordinary QR/BB™ module — previously found only in the ultimate Omega power cords — to a far wider audience for the first time.

This listing is for the 1.75m C-15 configuration, priced at $5,995 (compare at $6,500).

QR/BB™ Technology

The QR/BB™ (Charge Reservoir / Bulk Battery) module is the defining innovation of the Sigma X-QR. It acts as an electric charge reservoir — storing and releasing energy in a manner that dramatically improves a component’s access to instantaneous current.

• Improved dynamics — reduces dynamic strain heard from amplifiers connected with lesser power cables
• Lifelike timing and contrast — a presentation of dynamic nuance that cannot be replicated by any other means
• Island of pure silence — when used with reference-quality amplifiers and source components, the Sigma X-QR creates an extraordinarily quiet noise floor
• DTCD energy supercharging — the QR/BB technology essentially supercharges the component’s power supply with reserve levels of Dynamic Transient Current Delivery energy

Patent Number: US 10,031,536

Who It’s For

The Sigma X-QR is ideal for owners of reference-level amplifiers and source components who have already optimized their system and are ready to hear what a truly engineered power cable can do. It is particularly effective with high-current power amplifiers, DACs, and preamplifiers where instantaneous current delivery is critical to performance.
