QED Supremus Zr Speaker Cable - Factory Terminated Pair
If you are a true audio enthusiast, then the QED Supremus Zr Speaker Cable is an absolute must-have. This next-generation flagship loudspeaker cable from British audio specialists, QED, is the result of over five decades of technological evolution and refinement. It has been developed without any compromises, making it the pinnacle of audio innovation.
One of the most notable features of the Supremus Zr is its use of zirconia plugs and barrels. Zirconia is an advanced ceramic material that boasts high mechanical strength and superior scratch resistance, while also providing a lustrous gloss finish. This not only adds to the overall durability of the cable but also ensures that eddy currents cannot be established, resulting in minimal plug-induced distortion.
In addition to the zirconia plugs and barrels, the Supremus Zr also features a dedicated rhodium-plated, locking design. This design ensures maximum surface contact between the plug and terminals, which reduces resistance and improves the overall connection. Not only that, but rhodium is incredibly durable and will provide a maintenance-free connection for years to come.
But perhaps the most impressive feature of the Supremus Zr is its AirlocTM cold weld system. This high-pressure termination process compresses the conductors and plug together, creating a cold-welded area where they effectively become one. This results in a cable with no oxidisation or resistance degradation, ensuring the integrity and fidelity of the analogue music signal is maintained for the lifetime of the cable.
The Supremus Zr also utilises AircoreTM cordage technology, which combines hollow tubular conductors with polyester insulation and a special spiral construction. This minimises skin and proximity effects, evens out current density, and improves uniformity throughout the audio band. Additionally, the cable boasts ultra-low resistance conductors, with a large cross-sectional area, made from silver-plated, oxygen-free copper. This brings the amplifier electrically closer to the loudspeaker, allowing for better control and accurate reproduction of the original music signal.
And if all that wasn't enough, the Supremus Zr also undergoes cryogenic treatment, improving the microstructure of the copper by eliminating crystalline dislocations. This treatment has been found to improve the tone of numerous brass musical instruments, further showcasing the level of detail and care that has gone into the development of this cable.
Features
- Zirconia Airloc™ design for durability and resistance to eddy currents
- Cold weld system for lifetime functionality
- Rhodium-plated locking design for optimal contact

Why we stock QED
QED was one of the first brands we ever ordered, back in 2005 when we started. We have sold them every year since. Twenty-one years with one brand tells you something about how few of them come back, and QED still sit at the price point where most good systems begin.
New cables (even high-quality ones) benefit from a period of signal conditioning before reaching their optimum performance. The dielectric (insulation) around the conductors needs time to stabilise under the electromagnetic field created by signal flow. Rather than leaving this to you, we run cables on our Nordost Vidar burn-in machine before dispatch, up to the equivalent of 200 hours of use, in a fraction of the time. Your cable arrives performance-ready from the first listen.

Frequently Asked Questions
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.

Frequently Asked Questions
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.
