QED Optical

QED's multi-award winning Toslink optical digital audio cable relies on PMMA acrylic glass fibre to carry high frequency signals with ease, designed to minimise light absorption and allow more rays to travel along the cable by reducing the angle of incidence for internal reflection. This cable delivers a nicely balanced sound with full bass and punchy, precise high ends.
 

  

QED's Reference Optical Quartz Cable is built with 210 separate Glasscore™ (boro-silicate glass) fibres that produce straighter signal paths, delivering ultra-low jitter signal transfer. The result is a clear, open sound.
