QED Performance optical quartz

The QED Reference Optical Quartz is a superior Toslink digital optical audio cable made with real glass.

Reference Optical Quartz is the first of its kind, made up of 210 separate borosilicate glass fibres. The cable gives an extraordinary sound experience when connecting DACs, TVs, CD players and Blu-ray players to amplifiers or receivers, since it has a much higher bandwidth and only 1/10 of the attenuation of traditional acrylic fibres. Reference Optical Quartz far exceeds the demands of high-definition multichannel digital audio with a bandwidth of over 150 MHz, which is not affected at all by bending the cable.
