QED Coaxial Digital Audio 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.

OVERALL PERFORMANCE

Very Low Jitter

Very Low Jitter

Jitter is the undesired deviation from true periodicity of an assumed periodic signal in electronics and telecommunications, often in relation to a reference clock source. A cable displaying very low jitter has been measured at
typically 50ps.
