The optical reference quartz is the first of its kind and consists of 210 separate borosilicate glass fibers. With this cable, you can experience stunning sound when connecting DACs, televisions, CD players, and Blu-ray players to amplifiers or receivers, as it features a much higher bandwidth and only one-tenth the attenuation of conventional acrylic fibers. The optical reference quartz far exceeds the requirements for high-resolution digital multichannel audio with a bandwidth of over 150 MHz, remaining completely unaffected by bending the cable.
