QED Reference Optical Quartz


QED’s superior Toslink Optical Digital audio interconnect cable made with real glass.

Reference Optical Qz is the first of its kind, consisting of 210 separate boro-silicate glass fibers.  The cable allows you to experience stunning sound when connecting DAC’s, TV’s, CD players and Blu-Ray players to amplifiers or receivers because it has double the bandwidth and only 1/10th of the attenuation of the traditional acrylic fibers.  Reference Optical Quartz vastly exceeds the demands for high definition multi-channel digital audio with a bandwidth of up to 12MHZ which is totally unaffected by bending the cable.
