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.
QED's multi award winning Coaxial Optical digital audio cable
The multi award winning Performance Digital Audio cable is designed for connections between CD players, Blu-rayTM players or any other SPDIF source to your DAC or AV amplifier digital input. The QED design principle is to use a top down approach so this Performance cable shares many of the design characteristics of the top of the range Signature cable. In this instance the Performance cable uses Oxygen Free Copper conductors and twin electrical screening for enhanced signal integrity. All QED cables come with a QED Lifetime Guarantee.
