QED Reference Optical Quartz Cable Length:3m AudioQuest’s eARC Priority models offer world class AudioQuest’s eARC Priority models offer world class performance at the friendliest possible prices the S10+ covers both digital and analogue connectivity in a palm sized form factor Because the fibres are so small the different paths taken by the light rays are similar in length virtually eliminating the timing error and introducing less distortion and jitter QED have calculated that jitter (distortions caused by timing differences between the different light paths) in conventional optical cables could typically reach up to 145ps
