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

This is the Answer. This cable is for folks who want to elevate their system to another level. 

True to its reputation for migrating its most profound patented technologies into more affordable products, Shunyata Research has done it again. Previously found only in the ultimate Omega power cords, the QR/BB™ module takes a wrecking ball to power cord performance expectations. The QR/BB™ module possesses the ability to act as an electric charge reservoir, meaning it stores and releases energy in a manner that improves a component’s access to instantaneous current. Dynamics are actually improved, reducing any sense of dynamic strain often heard from amplifiers that are connected with lesser power cables. The sonic result is a lifelike presentation of timing and dynamic contrasts in sound that cannot be replicated by ANY other means.

The SIGMA-X QR creates an island of pure silence when used with reference quality amplifiers and source components. The QR/BB technology essentially supercharges the component’s power supply with reserve levels of DTCD energy.

For the first time, this remarkable QR/BB technology is available at a much lower price in order to reach far wider audience.
