QED Performance Optical Digital Toslink Cable

Founded by Bob Abraham and Ian Vine in 1973; QED has, over the past 40 years, acquired unparalleled knowledge and experience of hi-fi and home cinema cables and connectivity.

We are the market leader but we’re certainly not complacent. Our design engineers constantly investigate new technologies and undertake scientific research to ensure we always offer our customers the very best products on the market. As far back as 1994 we conducted the most extensive ever scientific investigation into the effects of speaker cables on hi-fi system performance. The results were astonishing, and can be found on our website under the heading ‘The Genesis Report'. The report produced clear evidence that speaker cables do matter, and we continue to use this information today. We urge you to try QED cables for yourself. If you do you’ll discover the differences in sound quality that QED hi-fi cables can really make.

QED Performance Optical Graphite

Experience the QED Performance Optical Digital Toslink Cable

Our Performance Optical Cable allows you to experience superior sound quality when connecting DAC's, TVs, CD players and Blu-Ray™ players to amplifiers or receivers. It uses a polymethyl methacrylate (PMMA) acrylic glass optical fiber that boasts half the signal attenuation per meter of the pervious model to comfortably transmit the higher bandwidth signals demanded by today's multi-channel digital audio links.

Polymethyl Methacrylate (PMMA) Acrylic Glass Optical Fibre

This new optical fibre boasts half the signal attenuation per meter of the previous Performance model, which means ‘Performance Graphite' comfortably transmits the higher bandwidth signals for multi channel audio. For HD multi channel audio applications (over 12MHz) please see our Reference Optical Quartz cable.

Very Low Jitter Design

At QED we have identified jitter or distortions caused by errors in the light transmission as a major factor in the deterioration of the audio signal. By incorporating precision cladding techniques jitter is reduced enabling a cleaner signal with better dynamics and a wider sound stage.

Very Low loss < 0.15dB attenuation per meter.
