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.
QED have changed people’s perspectives about hi-fi cables. Consumers no longer believe that ‘bell wire will do’ or that ‘any old cable will be fine’.
QED’s reputation for both innovation and technical excellence is known throughout the world. The latest computer aided design techniques allow their research and development team to keep pace with technological advances and deliver products that achieve the highest levels of performance and reliability.

QED XT25 Bi-Wire Speaker Cable
|
|
XT25 Bi-Wire with X-Tube™ Technology
XT25 Bi-Wire was designed as the natural complement to XT25, the 5-star-award winning*, entry-level X-Tube™ cable from QED. It incorporates four separate conductor bundles into a single, convenient X-Quad™ type geometry and is intended to present a much more enjoyable rendition of the musical performance when used in a bi-wire or bi-amped configuration.

QED XT40i Speaker Cable
|
|
XT40i with X-Tube™ Technology
As befits a company rapidly closing in on its fifth decades at the forefront of speaker cable design, QED’s brand new XT40i speaker cable builds on the formidable reputation of the XT40 cable it replaces and offers a decisive step up in sound quality.
This pure oxygen-free copper cable uses an evolution of QED’s established X-Tube technology to guarantee superb timing and stereo imaging, and adds the brand new and highly innovative Air Gap dielectric to bring unheard-of rhythmic accuracy and musicality to a cable of this modest price. Very low DC resistance adds unrivalled frequency response to XT40i’s already potent audio capability. The result is a cable that advances on the class-leading standards set by its predecessor.

Performance Audio 40i
Performance Audio 40i with QED Solid Complementary Conductor™ Technology and Anamate™ RCA plugs
Performance Audio 40i builds on the strengths of the original Performance Audio 40, and delivers an even more enjoyable and convincing sound - without affecting its prodigious value for money. Using the principles laid down in its industry-defining Genesis Report, as well as some startlingly original technology (including the ground-breaking Solid Complementary Conductors and Anamate plugs), QED has created an interconnect that puts as much distance between itself and its nominal competition as the original Performance Audio 40 did over six years ago.

QED Reference XLR 40 Analogue Interconnects
|
|
Reference XLR 40 builds on the multi-award winning Audio 40 range of products, now available in XLR form.
XLR 40 is designed primarily for low capacitance as this has been identified by QED as a major factor which leads to a high fidelity experience. Further steps have been taken to eliminate minute timing errors in the cable by the use of a special floating Zn/Mn ferrite jacket alongside use of QEDs unique 'Tri-Conductor' technology reducing signal to ground capacitance to vanishingly low levels.

QED Reference Optical Quartz Digital Interconnect
|
|
QED's superior Toslink Optical digital audio interconnect cable made with real glass
Reference Optical Quartz is the first of its kind, consisting of 210 separate boro-silicate glass fibres. The cable allows you to experience stunning sound when connecting DACs, TV’s, CD players and Blu-Ray players to amplifiers or receivers because it has a much higher bandwidth and only 1/10th of the attenuation of traditional acrylic fibres. Reference Optical Quartz vastly exceeds the demands for high definition multi-channel digital audio with a bandwidth of over 150MHz which is totally unaffected by bending the cable.

QED Reference Digital Audio 40 Interconnect
|
|
Reference Digital Audio 40, the new standard for digital coaxial S/PDIF signals.
Reference Digital Audio 40 utilises a carefully engineered geometry to achieve the precise characteristic impedance required for the maximum transfer of S/PDIF signals. Silver plated conductors deliver a low resistance path for high frequencies and QED "Digiloc" plugs more closely match the cable's characteristic impedance, reducing return loss by up to 1dB when compared to conventional RCA plugs. This ensures optimal signal transfer and improved micro-timing of the audio signal.
