what's this?

We can burn-in your cable for up to 96 hours FREE of charge using our Nordost VIDAR cable burner. This is a £3000 machine that will optimise the performance of your cables from day one. This means the cables will be in optimum performance mode when you receive them, so you'll be able to make a performance assessment quickly rather than waiting 70 hours+ of usage. The result of conditioning cables with the Nordost VIDAR is, improved sound staging, increased detail, and an overall more musical presentation. Please Note: we are unable to burn-in cables with stripped bare ends or BFA-only plugs. (This does not apply to BFA/Banana plugs). Cables are burnt-in for the selected period AFTER your order has been processed. This service is offered at Future Shop's discretion and we cannot guarantee all burn-in requests are fully completed during busy periods.

Reference XLR 40 builds on the multi-award winning audio 40 range of products, now available in digital AES/EBU form.

QED Reference Digital XLR 40 AES/EBU Audio Cable 

 

Reference XLR 40 builds on the multi-award winning audio 40 range of products, now available in digital AES/EBU form.

XLR 40 is designed primarily for low jitter 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-Conductortm' technology that reduces signal to ground capacitance to vanishingly low levels. 

 

Award Winning Heritage

Reference XLR 40 builds on the multi-award winning Audio 40 range of products, now available in XLR form. QED have joined forces with world renowned professional audio connector supplier Neutrik (UK) to bring you an innovative new XLR balanced interconnect cable with legendary build quality and reliability. 

 

Professional Standard Neutrik Plugs

Neutrik XX-14 Nickel Series XLR gold plated connectors are provided as standard with Reference XLR 40 cables. These connectors are rugged and reliable and are the connector of choice for audio professionals around the world. They are particularly suited to QED's Tri-ConductorTM geometry due to the additional ground spring contacts which make for better shell ground continuity for the unique electrostatic screen which is only connected at the source end of the cable. 

 

Just Listen

Silver plated conductors, LDPE dielectrics and legendary build quality combine to create audible sonic improvements. We urge you to compare Reference XLR 40 not only to your favourite cable but also alternative brands and models at any price! 

 

Floating Ferrite Jacket

Absorbs high frequency noise signal components outside the audio band. When measured using high frequency measurement equipment, Audio 40 products convey a comparably cleaner and tighter signal pattern when its special Zn/Mn ferrite jacket is present. This has a beneficial effect on audio signal micro-timing, reducing digital jitter and timing errors to an ultra low level. 

 

Unique Tri-Conductor Technology

QEDs unique Tri-Conductor technology uses a third Silver plated 99.999% OFC conductor which is integrally twisted alongside the similarly constructed signal pair to carry the ground return currents. This reduces signal to ground capacitance to vanishingly low levels affording the cable improved common mode rejection of mains hum pickup over ordinary "hot cold and screen" cables. This geometry is particularly effective in pro hi-fi audio applications when connecting pre and power amps using balanced cables or high end streamers to DACs using digital XLR AES/EBU. 

 

Ferrite Insulation Technology


A special floating Zn/Mn Ferrite jacket is used within the Audio 40 cordage to absorb very high frequency noise components outside of the audible band that have an adverse effect on the micro-timing of the audio signal.

Tri Conductor Technology


QEDs unique Tri-Conductor technology uses a third Silver plated 99.999% OFC conductor which is integrally twisted alongside the similarly constructed signal pair to carry the ground return currents.

Ultra 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 ultra low jitter has been measured at
typically 30ps.

About QED Cables Made in United Kingdom

QED is an award winning British company with over 40 years of experience in the audio-visual connectivity industry.

In 1973 Bob Abraham and Ian Vine founded QED Audio Products and changed the way people think about hi-fi cables. By the time QED 79 strand speaker cable was launched in 1978, it wasn’t looked upon as ‘just another speaker cable’ but was instead regarded as a serious hi-fi component, making a fundamental change in the way people thought about cables.

QED's reputation for 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. This is why QED products are recommended by so many of the world’s leading hi-fi and home theatre equipment manufacturers.

QED offer a range of connectivity products spanning from both consumer and installation cables, wireless products and switching devices to satisfy every audio visual need.

QED is Europe's number one award winning connectivity brand and has won more prestigious cable awards from ‘What Hi-Fi? Sound & Vision’ magazine than any other brand (Awards 1981–2013).

Free Cable Burn-In Service Option Using The Nordost Vidar Machine

 

Please Note: We are unable to burn-in cables with stripped bare ends or BFA plugs. Cables are burnt-in for the selected time period AFTER your order has been processed. Custom-length cables are burnt-in for the selected time period AFTER they have be terminated by the manufacturer or our engineers. 

Our cable burn-in service is a non-chargeable service and is provided by Future Shop at its discretion. We will attempt to fulfil all burn-in requests for the specified time periods. However, during extremely busy periods, we regret we may not be able to meet demand for all requests due to the limited connections available on the Nordost Vidar cable conditioning machines.

We are pleased to offer a free cable burn-in service for this cable when purchased through Future Shop. The Nordost VIDAR cable burn-in machine combines three distinct functions all in one operation:

  • It neutralises charges that build up around the cables and the insulation
  • It provides a very wide band and deep conditioning into the conductor core, which produces changes in the way signals pass through the metal.
  • It ultrasonically conditions the surface of the conductors.

 

Nordost Vidar Burn-in Machine

 

The VIDAR uses a proprietary combination of composite and complex signals to condition the cables. Parts of the signal oscillate at ultra-low frequencies, while other parts are in ultra-high ranges which extend beyond the range of video frequencies. The signal bounces in a ping-ping ball-like fashion from one end of the cable to the other. During the burn-in process, ultra-low frequencies penetrate deep into the core of the cable. The ultra-high frequencies zip along the surface. This method of signal transmission is set up to beat harmonics, or heterodynes, between the two complex waveforms. In the digital domain, this would be referred to as aliasing products. These beat frequencies penetrate all layers of the cable.  

The design of the circuitry also has a unique feature which drives electrons above the conductor into the dielectric (or insulation) area. The VIDAR not only sends ping pong signals along the cable, it also sends a similar signal from the centre core to the outer shield in the case of interconnect cables. This function neutralises the electrical charges discussed above.

So, what does that all mean to me?
The end result of conditioning cables with the Nordost VIDAR is improved sound staging, increased detail, and an overall more musical presentation.
