AudioQuest ThunderBird XTRM Speaker Cable
The AudioQuest ThunderBird XTRM is a full-range speaker cable that opens AudioQuest's flagship Mythical Creature series, built for listeners who want their amplifier and loudspeakers to communicate with as little interference as possible. ThunderBird XTRM can be used on its own as a single-wire full-range cable, or paired with AudioQuest's dedicated BassZilla bass-only cable to form a bi-wire assembly for speakers with separate bass and treble inputs. Either way, the aim is the same: to let the music arrive with its timing, scale and texture intact, rather than softened or hardened by the cable in between.
At the heart of the ThunderBird XTRM are solid 10AWG conductors combining AudioQuest's extreme-purity No-Grain Copper with Perfect-Surface Copper+. Solid conductors avoid the strand interaction that blurs dynamics in stranded cable, while the refined copper minimises the grain boundaries that add distortion. ZERO-Tech geometry removes the electrostatic field between the high and low conductors, so the cable has no characteristic impedance to mismatch with the amplifier or speaker, and transient current flows without restriction. The result is a sense of effortless dynamic contrast, with leading edges that start and stop cleanly.
Noise control is equally thorough. A 72v Dielectric-Bias System with RF Noise-Trap polarises the insulation, lowering its noise floor so that quiet passages emerge from a darker background. Graphene+Carbon Mesh-Network layers and Perfect-Surface Silver drain wires absorb and divert radio-frequency noise before it can modulate the signal, and every conductor is direction-controlled so that induced noise is drained away from where it does harm. Foamed Polypropylene insulates the positive conductors, and each cable receives AudioQuest's Permanent Molecular Optimisation treatment to reduce burn-in time.
The ThunderBird XTRM is finished in a blue nylon braid with synthetic breakouts and plug bodies, chosen over metal to avoid inducing RF noise into the conductors. Terminations are cold-welded, solder-free and hanging-silver plated directly over pure red copper, offered as banana plugs or U-spades. Each pair is supplied in 1.5m, 2m, 2.5m, 3m, 3.5m or 4m lengths.
What AudioQuest say about the ThunderBird XTRM
ThunderBird XTRM is the powerful entry into AudioQuest's critically acclaimed Mythical Creature speaker cables. Now employing a carefully finessed combination of extreme-purity No-Grain Copper and Perfect-Surface Copper+ conductor metals, and featuring tried-and-true AQ design elements such as direction-controlled conductors, optimized insulation, and 72v Dielectric-Bias System, ThunderBird XTRM is a perfect choice for discerning audiophiles eager to optimize their system and enhance their listening experience.
ThunderBird XTRM speaker cables may be used in one of two ways: either as ideal Full-Range cables, or, in combination with a dedicated Bass-Only cable, BassZilla, in a BiWire cable assembly of unparalleled performance.
BiWiring
When a speaker has separate Bass and Treble inputs, running separate cables to the Treble and Bass inputs significantly reduces distortion. BiWiring prevents the strong bass signal from modulating the delicate treble signal, like taking the waves out of the water when you swim.
When using ThunderBird XTRM for Treble, AudioQuest BassZilla Bass-Only cable is the ideal choice for running to the speakers' Bass inputs, reducing current modulation, and, even more importantly, taking RF interference off the amplifier's output. A BiWire Combo with Bass-Only and ZERO cables joined together at the amplifier is usually most convenient, though joining them is optional. When TriWiring, use Bass-Only cables on the Midrange and Bass inputs.
Do not Double-BiWire with two ZERO-Tech cables. Your amp will distort.
Almost all speakers come with Bass/Treble Jumpers that are worse than driving with a compact-spare tire. If you single-wire your speakers, please use better Jumpers. AudioQuest offers a range of excellent options starting with the affordable Bare Naked Jumpers.
ZERO-Tech (No Characteristic Impedance)
The only way to prevent characteristic-impedance mismatch-effects between a cable and its attached source and load circuits is for the cable not to have a characteristic-impedance. ZERO-Tech accomplishes this by eliminating any electrostatic field between the cable's high and low signal conductors - enabling uncompressed current transfer. All-important transient current is unrestricted and RF Noise-Dissipation is more effective and linear.
Solid No-Grain Copper (NG-C) and Perfect-Surface Copper+ (PSC+) Conductors
Solid conductors prevent strand-interaction, a major source of dynamic distortion. A carefully finessed combination of AudioQuest's extreme-purity No-Grain Copper and Perfect-Surface Copper+ achieves exceptionally low distortion and maximizes RF noise-dissipation.
Linear Noise-Dissipation
The Earth is permeated with RF-Noise from satellites, cellular, WiFi, etc. Graphene+Carbon Mesh-Network, ZERO-Tech, direction-controlled No-Grain Copper (NG-C) conductors, 72v DBS, and Perfect-Surface Silver (PSS) RF shield drains effectively minimize damaging RF noise.
72v Dielectric-Bias System (DBS) with RF Noise-Trap
Insulation is also a dielectric that acts like a shunt-filter. Biasing the dielectric both minimizes dielectric-noise and linearizes the filter, significantly improving wide-bandwidth dissipation of induced noise.
Perfect-Surface Silver RF Shield Drains
Enable optimal RF-Noise Dissipation.
Permanent Molecular Optimization (PMO)
By optimally and efficiently applying a high-frequency AC signal many times greater than any audio system could possibly provide over any length of time, transient intermodulation distortion and the cable burn-in process are significantly reduced.
Cold-Welded Red-Copper Spades or Bananas
Cold-Welding avoids the introduction of heat and distortion-causing materials like solder. The bare parts are submerged (hung) in silver instead of tumbled in a lower-grade solution. Speaker breakouts and plug casings are synthetic, not metal, to avoid inducing RF Noise into the conductors.
Directionality
All drawn metal strands or conductors have a non-symmetrical, and therefore directional, grain structure. AudioQuest controls the resulting RF impedance variation so that noise is drained away from where it will cause distortion. A fundamental aspect of AudioQuest's multifaceted Noise-Dissipation technology, Direction-Controlled Conductors ensure induced noise is dissipated and drained in the direction of least harm.

About AudioQuest
Californian cable maker covering analogue, digital, speaker and power cables, with patented conductor and dielectric designs.
AudioQuest is based in Irvine, California, and makes cables for nearly every connection in a system: analogue interconnects, USB, HDMI and Ethernet, speaker cables and AC power cables. Its designs come back to four ideas: solid conductors, directionality, noise dissipation and the quality of the metal.
Read more about AudioQuest Show less
Conductor and metal choices come first
Solid conductors and metal quality are two of the ideas AudioQuest returns to across its range. HyperLitz, a conductor construction patented in 1988, is another. Directionality, the principle that a cable is built to carry signal in one direction, is the fourth.
Noise is treated as a separate design problem
AudioQuest lists its noise-dissipation technologies as ZERO-Tech, RF/ND-Tech and the Dielectric-Bias System, which was patented in 2004. They are applied alongside the conductor work rather than in place of it, and which ones a cable carries depends on the model and its price.
One brand across the whole system
AudioQuest also makes AC power cables, Niagara and PowerQuest power conditioners and DragonFly DACs alongside its analogue, digital and speaker cables. If you are building or upgrading a system, that means every cable in the chain, and the power feeding it, can come from one design approach.
Why we stock AudioQuest
We took AudioQuest on for HDMI. When the 1.4 spec arrived in 2009 they were the first supplier who could actually get the cables to us, at a point when almost nobody could. The power cables turned out to be just as good, and they are now a bigger part of what we sell than the HDMI ever was.

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.

Free Premium Cable Burn-In Service: Experience the Power of Nordost VIDAR 2 Machine
We are thrilled to unveil our upgraded cable burn-in service, now featuring the cutting-edge VIDAR 2 burn-in machine. At Future Shop, we strive to provide the best possible experience for our customers, and this enhanced service is designed to unlock the true potential of your high-end cables. Read on to discover the exceptional benefits and advancements offered by the VIDAR 2 machine.
Please note: We are unable to burn-in cables with stripped bare ends or BFA plugs. Cable burn-in occurs after your order has been processed for the selected time period. For custom-length cables, burn-in takes place after termination by the manufacturer or our skilled engineers.
The Nordost VIDAR cable burn-in machine seamlessly combines three vital functions into a single operation:
- Neutralising charges around cables and insulation: The VIDAR 2 effectively dissipates any built-up charges, creating an optimal environment for signal transmission.
- Deep conditioning into the conductor core: With its wide band and profound conditioning capabilities, the machine induces significant changes in signal passage through the metal, resulting in enhanced performance.
- Ultrasonic surface conditioning of conductors: The VIDAR 2 employs ultrasonic technology to refine the conductor surface, further refining the signal quality.
In addition to all the advantages of its predecessor, the VIDAR 2 introduces remarkable improvements, including:
- Complex burn-in signal with wider bandwidth and richer content
- Enhanced directionality for cables
- FOUR burn-in zones - including a new digital zone for USB, Ethernet, and Coaxial (BNC) cables.
Using a proprietary blend of composite and complex signals, the VIDAR 2 ensures comprehensive cable conditioning. The signal consists of ultra-low and ultra-high frequencies, surpassing video frequency ranges. The signal effectively penetrates the core at ultra-low frequencies by oscillating throughout the cable while swiftly traversing the surface at ultra-high frequencies. This transmission methodology counters harmonics and heterodynes between the two complex waveforms, improving signal performance throughout all cable layers.
Furthermore, the circuitry design boasts a unique feature that drives electrons above the conductor into the dielectric or insulation area. This process neutralizes any electrical charges that may impact the signal integrity. With the Nordost VIDAR, we go beyond merely sending ping-pong signals along the cable; we also ensure a balanced signal flow from the centre core to the outer shield in interconnect cables.
What does all this mean for you?
Conditioning your cables with the Nordost VIDAR yields remarkable benefits, including enhanced sound staging, heightened detail reproduction, and a more captivating and musical presentation.
We offer our cable burn-in service as a complimentary offering at the discretion of Future Shop. While we strive to accommodate all burn-in requests for the specified time periods, please understand that during exceptionally busy periods, we may be unable to fulfill all demands due to the limited connections available on the Nordost VIDAR cable conditioning machines.

AudioQuest lists its noise-dissipation technologies as ZERO-Tech, RF/ND-Tech and the Dielectric-Bias System, which was patented in 2004. They are applied alongside the conductor work rather than in place of it, and which ones a cable carries depends on the model and its price.
One brand across the whole system
AudioQuest also makes AC power cables, Niagara and PowerQuest power conditioners and DragonFly DACs alongside its analogue, digital and speaker cables. If you are building or upgrading a system, that means every cable in the chain, and the power feeding it, can come from one design approach.
Why we stock AudioQuest
We took AudioQuest on for HDMI. When the 1.4 spec arrived in 2009 they were the first supplier who could actually get the cables to us, at a point when almost nobody could. The power cables turned out to be just as good, and they are now a bigger part of what we sell than the HDMI ever was.

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.

Free Premium Cable Burn-In Service: Experience the Power of Nordost VIDAR 2 Machine
We are thrilled to unveil our upgraded cable burn-in service, now featuring the cutting-edge VIDAR 2 burn-in machine. At Future Shop, we strive to provide the best possible experience for our customers, and this enhanced service is designed to unlock the true potential of your high-end cables. Read on to discover the exceptional benefits and advancements offered by the VIDAR 2 machine.
Please note: We are unable to burn-in cables with stripped bare ends or BFA plugs. Cable burn-in occurs after your order has been processed for the selected time period. For custom-length cables, burn-in takes place after termination by the manufacturer or our skilled engineers.
The Nordost VIDAR cable burn-in machine seamlessly combines three vital functions into a single operation:
- Neutralising charges around cables and insulation: The VIDAR 2 effectively dissipates any built-up charges, creating an optimal environment for signal transmission.
- Deep conditioning into the conductor core: With its wide band and profound conditioning capabilities, the machine induces significant changes in signal passage through the metal, resulting in enhanced performance.
- Ultrasonic surface conditioning of conductors: The VIDAR 2 employs ultrasonic technology to refine the conductor surface, further refining the signal quality.
In addition to all the advantages of its predecessor, the VIDAR 2 introduces remarkable improvements, including:
- Complex burn-in signal with wider bandwidth and richer content
- Enhanced directionality for cables
- FOUR burn-in zones - including a new digital zone for USB, Ethernet, and Coaxial (BNC) cables.
Using a proprietary blend of composite and complex signals, the VIDAR 2 ensures comprehensive cable conditioning. The signal consists of ultra-low and ultra-high frequencies, surpassing video frequency ranges. The signal effectively penetrates the core at ultra-low frequencies by oscillating throughout the cable while swiftly traversing the surface at ultra-high frequencies. This transmission methodology counters harmonics and heterodynes between the two complex waveforms, improving signal performance throughout all cable layers.
Furthermore, the circuitry design boasts a unique feature that drives electrons above the conductor into the dielectric or insulation area. This process neutralizes any electrical charges that may impact the signal integrity. With the Nordost VIDAR, we go beyond merely sending ping-pong signals along the cable; we also ensure a balanced signal flow from the centre core to the outer shield in interconnect cables.
What does all this mean for you?
Conditioning your cables with the Nordost VIDAR yields remarkable benefits, including enhanced sound staging, heightened detail reproduction, and a more captivating and musical presentation.
We offer our cable burn-in service as a complimentary offering at the discretion of Future Shop. While we strive to accommodate all burn-in requests for the specified time periods, please understand that during exceptionally busy periods, we may be unable to fulfill all demands due to the limited connections available on the Nordost VIDAR cable conditioning machines.
