Audioquest Lone Ranger ZERO-Tech (2 x 4m) fork
Overview
The Lone Ranger succeeds the Robin Hood model in AudioQuest’s Folk Hero series, positioned between entry-level cables and the Mythical Creatures range. Each polarity features an 11.6 mm diameter, with a dual-housing construction separating the positive and negative conductors. The cable incorporates approximately one-third more PSC+ copper compared to previous models, in a design aimed at lowering impedance and optimizing frequency response.
ZERO-Tech technology at the heart of the design
The complete method for eliminating characteristic impedance mismatches between a cable and the connected source and load elements is for the cable to have no fixed characteristic impedance value. This is precisely what ZERO-Tech achieves. ZERO-Tech eliminates the electrostatic field between the cable’s high and low signal conductors, allowing linear dissipation of radio frequency noise and uncompressed transients.
In a conventional cable, characteristic impedance creates a mismatch with the amplifier’s output impedance and the speaker’s load impedance. By eliminating all electrostatic interaction between the cable’s signal conductors, ZERO-Tech enables uncompressed current transfer. Transient current, crucial for musical dynamics, flows without restriction, and RF noise dissipation becomes linear across the entire frequency band.
Perfect-Surface PSC+ copper conductors
High-purity PSC+ copper conductors prevent strand interaction, a major source of transient intermodulation distortion. Unlike multi-strand cables where magnetic and electrical interactions between strands generate distortions, the Lone Ranger’s solid conductors ensure more coherent signal transfer.
Perfect-Surface technology applied to copper minimizes surface imperfections and reduces grain boundaries in the metal’s crystalline structure. These grain boundaries constitute points of resistance and distortion in any metallic conductor. By drastically reducing them, PSC+ copper offers increased clarity and a notable decrease in audible harshness in the high frequencies.
72 V DBS system with RF noise trap
The constant DC potential of AudioQuest’s 72 V dielectric-bias system polarizes the insulation, significantly reducing dielectric noise. A cable’s insulation acts as a capacitor: it stores energy during signal passage, then releases it in a time-shifted manner and at other frequencies. This phenomenon creates a form of temporal blur that masks micro-details.
The DBS system also linearizes radio frequency noise dissipation over a wide bandwidth. Powered by a battery placed in an external housing attached to the cable, the system maintains a constant 72-volt charge that stabilizes dielectric properties. Unlike traditional cable break-in that requires weeks of use, DBS maintains this stabilization permanently.
Level 7 noise dissipation
The Lone Ranger incorporates a particularly sophisticated noise dissipation system. The cable employs thicker carbon-loaded PVC in its construction, with an added graphene layer, and 4% silver-plated shield drainage wires. This multi-layer strategy targets radio frequency interference that saturates our modern environment: cellular networks, WiFi, satellites, Bluetooth.
The controlled-direction conductors are designed to drain RF noise away from sensitive amplification circuits. Each conductor has a specific orientation, determined by listening during manufacturing, that optimizes noise evacuation toward the cable end where it will cause the least damage. The 4% silver drainage wires contribute significantly to effective dissipation of high-frequency interference.
Physical construction and ergonomics
Slightly more compact than the Brave Heart with its 11.6 mm outer diameter versus 14.1 mm per polarity, the Lone Ranger adopts a construction that places the positive and negative conductors in separate round housings. This approach offers several advantages: simplified handling, reduced magnetic interactions between polarities, and ease of installation even in complex configurations.
Superior polypropylene insulation linearizes and widens the noise dissipation bandwidth. Polypropylene presents a favorable dielectric constant and dimensional stability that minimizes distributed capacitance. This distributed capacitance, if not controlled, creates blurred distortion in the upper spectrum.
The black-on-black braided nylon outer jacket protects the assembly while providing discreet aesthetics. There is no metal in the cable dressings or connector bodies, which would prevent re-radiation and capacitive coupling of RF noise into the cable.
Cold-welded connections
Cold-welded connections avoid introducing heat and distortion-causing materials like solder. In a cold-welding process, bare copper parts are immersed in a bath of pure silver rather than tumbled in an inferior quality solution. This method creates a gas-tight connection that preserves signal integrity.
Connectors are available as banana plugs or spades, all in silver-plated red copper. The choice between bananas and spades often depends on the type of terminals present on the amplifier and speakers. European-standard-compliant terminals sometimes make it difficult to tighten spade lugs with high pressure, in which case bananas constitute the best choice.
Permanent Molecular Optimization (PMO)
By optimally and efficiently applying a high-frequency alternating signal far beyond what an audio system could provide over any duration, transient intermodulation distortion and the cable break-in process are significantly reduced. This extreme treatment of dielectric materials, performed at the factory, permanently modifies the insulation’s properties.
The result: the cable offers its best performance from first use, without requiring weeks of break-in. Where some cables require hundreds of hours before reaching their full potential, the Lone Ranger delivers transparency and musicality immediately.
Comparison with the Robin Hood
The Lone Ranger succeeds the Robin Hood, a popular model in the Folk Hero series. The main improvements concern the amount of conductive metal, optimized polypropylene insulation, and additional noise dissipation layers. The Lone Ranger incorporates thicker carbon-loaded PVC, an added graphene layer, and 4% silver shield drainage wires, where the Robin Hood used a less sophisticated shielding strategy.
These developments translate into reduced noise floor, better definition in the bass, and more precise articulation of midrange and treble. The Lone Ranger retains the Robin Hood’s general approach—solid PSC+ conductors, ZERO-Tech, 72 V DBS—while refining every aspect of the design.

Frequently Asked Questions
What is the difference between banana plug connectors and spade lugs for this cable?
Banana plugs offer quick insertion and removal, particularly suited to amplifiers whose terminals don’t accept strong tightening. Spade lugs generally allow a tighter and more stable connection, but some European-standard-compliant terminals make their use difficult. AudioQuest offers U-shaped spades that adapt to any type of terminal when doubt exists.
Does the DBS system require battery replacement?
The DBS housing contains a battery that maintains the dielectric-bias charge. This battery has a lifespan of several years under normal usage conditions. When replacement becomes necessary, AudioQuest provides replacement batteries and instructions to perform the operation without difficulty.
Can I use the Lone Ranger for bi-wiring immediately?
The Lone Ranger alone can power a bi-wirable speaker using jumpers between the terminals. For optimal bi-wiring, you’ll need to wait for the release of the BigFoot BASS cable in early 2026. This combination—Lone Ranger on the highs and BigFoot on the bass—will fully exploit the capabilities of compatible speakers. Using two Lone Ranger cables in parallel is not recommended due to possible high-frequency resonances.
Does the PMO treatment make cable break-in unnecessary?
The PMO treatment applied at the factory considerably reduces the break-in time usually required. The cable reaches a high performance level from installation. Some users nevertheless report subtle improvements after a few dozen hours of use, but these changes remain minor compared to what is observed with untreated cables.
How do I determine the cable's connection direction?
The Lone Ranger’s conductors are directional to optimize RF noise evacuation. Arrows clearly marked on the connectors indicate the installation direction: they point from the amplifier toward the speakers. This orientation, determined by listening during manufacturing of each conductor batch, ensures optimal dissipation of interference.
Is the Lone Ranger suitable for tube amplifiers?
The Lone Ranger works perfectly with tube amplifiers. Its low impedance and ZERO-Tech design help the amplifier—whether tube or transistor—transfer the signal to the speakers with less compression. Tube amplifiers, often sensitive to load impedance, can particularly benefit from the cable’s characteristic-impedance-free approach.
