QED Reference XLR 40 2 XLR to 2 XLR Audio Cable - Custom Length
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.
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-Conductor™ 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.
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.

Enhance Your Experience: Free Cable Burn-In Service with Nordost VIDAR Machine
Please take note of the following details regarding our cable burn-in service:
- Cable Compatibility: We regret to inform you that we cannot burn-in cables with stripped bare ends or BFA plugs. In order for cables to undergo the burn-in process, they should be terminated or have connectors.
- Timing: Cables will be burnt in for the selected period after processing your order. For custom-length cables, the burn-in process will occur after they have been terminated by the manufacturer or our engineers unless specified otherwise in the product description.
- Availability: Future Shop provides our cable burn-in service free of charge, but its availability is at our discretion. While we strive to fulfil all burn-in requests for the specified time periods, please understand that during exceptionally busy periods, we may be unable to meet the demand due to limited connections on the Nordost Vidar cable conditioning machines.
The Nordost VIDAR cable burn-in machine integrates three key functions into one operation:
- Charge Neutralisation: It eliminates charges that accumulate around the cables and their insulation, ensuring a more balanced electrical environment.
- Deep Conditioning: The machine provides a wide band and deep conditioning process that affects the conductor core, resulting in changes to the signal transmission through the metal. This deep conditioning enhances the cable's performance.
- Ultrasonic Surface Conditioning: The VIDAR machine utilizes ultrasonic waves to condition the surface of the conductors, optimizing their contact and overall conductivity.
The VIDAR employs a proprietary combination of composite and complex signals to condition the cables. These signals comprise ultra-low and ultra-high frequencies, extending beyond the range of video frequencies. The signal moves back and forth along the cable, penetrating deep into the core with ultra-low frequencies and traversing the surface with ultra-high frequencies. This transmission method generates beat harmonics between the two complex waveforms, which permeate all layers of the cable. The circuitry of the VIDAR also drives electrons from the conductor into the insulation area, neutralizing electrical charges.
So, what does this all mean for you?
The ultimate outcome of conditioning cables with the Nordost VIDAR is improved sound staging, increased detail, and an overall more musical presentation in your audio system.
Now, you may wonder why cable burn-in is necessary. During cable manufacturing, gasses become trapped as insulation is applied over the conductors. Additionally, new cables often possess high electrical charges, resulting in a brittle and bright sound that lacks the desired detail and depth for music production.
When cables undergo burn-in, the trapped gasses are dissipated, and small impurities in the conductor metals begin to exhibit diode-like behaviour, favouring current flow in a specific direction.
Here are the physical effects of the burn-in process:
- Charge Neutralisation: The burn-in process neutralizes charges in the conductors and insulation, promoting a more balanced electrical environment.
- Wide Bandwidth Frequencies: The conditioning affects how signals pass through the metal, enabling a wider range of frequencies to penetrate all cable layers.
- Signal Transmission: The burn-in process establishes the directionality of the cable, optimizing signal transmission from one end to the other.
When cables are properly burnt in, you can expect the following audible changes in your audio system:
- Fuller and Natural Sound: Your system should be capable of producing a more immersive and realistic performance with a fuller and more natural sound.
- Increased Detail: You may notice enhanced details and nuances in the music, allowing you to perceive subtle elements that were previously hidden.
- Improved Soundstage: The dimensionality of your system's soundstage can be greatly improved, creating a more spacious and immersive listening experience.
At Future Shop, our goal is to maximise your satisfaction. That's why we offer a free burn-in service on all our cables before they arrive at your door, enabling you to sit back and enjoy the benefits of properly conditioned cables in your audio system.

Living with these cables for a year now and they don't fail to empress... Open, dynamic, detailed, very easy to listen to on my modest setup. (system details above in a review I left in January 2019) for me these cables are exceptional value for money and I'm a big fan of QED... I have other cables of QED and they to are great value for the money.
Any one looking to upgrade way past the standard RCA leads supplied with equipment would do well to give these a demo. I had mine burnt in for the 96hrs offered by Future shop and I would strongly recommend it and give it a fair bit of burning in your system before making any rash judgement and returning... I love these cables and 100% recommended,
And I 100% recommend Future shop... GREAT IMPARTIAL ADVICE, SERVICE AND SUPPORT. 5 STAR'S ALL THE WAY.

I originally ordered 1m lengths of these cables but as they were being connected to my new powered speakers I found I needed to move the speakers further out into the room away from the corner and sidewalls.
I contacted Future Shop and spoke with Glyn and explained I got my measurements wrong and would it be possible to exchange them for 2m custom lengths. I was very happy to be told that was not a problem. I'm using the cables from my Yamaha CDs 2100 SCAD player to my new Quad Artera preamplifier and then to my new Elac Navis arb-51 powered speakers.
I'm still running the set up in, but so far I'm very impressed. Details, focus, leading edges, clean, clear, open and spacious sound that is so much fun and never sounds hard, harsh or compressed.
I'm very happy with the cables and every bit impressed with Future Shop and the staff, looking fwd to doing business with them when I have the funds to upgrade all my power cables. 5 STAR'S ALL THE WAY.

I ordered a custom length pair and very quickly received the cables 'burnt in'.
I shall be using them shortly with some new equipment but meanwhile I swopped out some considerably more expensive interconnects to see how the QED compared.
First off, they may be burnt in but they still need 5 hours or more in the system for them to settle down and open up - so dont judge by a short listen! After that they aquitted themselves very well. Not quite as detailed but extremely easy to get on with and neutral. No exageration at either end of the spectrum. At 25% of the cost of the other cable they delivered about 70% of the performance. Highly recommended for longer runs, will not dissapoint even in a revealing system.
