Audioquest Lone Ranger ZERO-Tech (2 x 3m) 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 design separating the positive and negative conductors. The cable incorporates roughly one-third more PSC+ copper than previous models, in a design aimed at lowering impedance and optimizing frequency response.
ZERO-Tech at the heart of the design
The comprehensive 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. That’s precisely what ZERO-Tech achieves. ZERO-Tech eliminates the electrostatic field between the cable’s high and low signal conductors, enabling linear radio-frequency noise dissipation and uncompressed transients.
In a conventional cable, the characteristic impedance creates a mismatch with the amplifier’s output impedance and the speaker’s load impedance. By removing any 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 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 distortion, the Lone Ranger’s solid conductors ensure a more consistent signal transfer.
The Perfect-Surface technology applied to copper minimizes surface imperfections and reduces grain boundaries within the metal’s crystalline structure. These grain boundaries are points of resistance and distortion in any metal conductor. By drastically reducing them, PSC+ copper offers increased clarity and a notable decrease in audible hardness 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 like a capacitor: it stores energy as the signal passes through, then releases it later in time and at other frequencies. This phenomenon creates a form of temporal smearing that masks micro-detail.
The DBS system also linearizes radio-frequency noise dissipation over a wide bandwidth. Powered by a battery housed in an external module attached to the cable, the system maintains a constant 72-volt charge that stabilizes dielectric properties. Unlike traditional cable break-in, which requires weeks of use, DBS maintains this stabilization continuously.
Level-7 Noise-Dissipation
The Lone Ranger features a particularly sophisticated noise-dissipation system. The cable employs a thicker carbon-loaded PVC in its construction, with an added graphene layer, and 4% silver-plated shield drain wires. This multilayer strategy targets the radio-frequency interference saturating our modern environment: cellular networks, WiFi, satellites, Bluetooth.
Direction-controlled conductors are designed to drain RF noise away from sensitive amplification circuits. Each conductor has a specific orientation, determined by listening tests during manufacturing, that optimizes noise evacuation toward the cable end where it will do the least harm. The 4% silver drain wires contribute significantly to effective high-frequency interference dissipation.
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: easier handling, reduced magnetic interaction between polarities, and ease of installation even in complex setups.
A superior polypropylene insulator linearizes and broadens the noise-dissipation bandwidth. Polypropylene features a favorable dielectric constant and dimensional stability that minimizes distributed capacitance. If left unchecked, this distributed capacitance creates smearing distortion in the upper spectrum.
The black-on-black braided nylon outer jacket protects the assembly while imparting a discreet aesthetic. There is no metal in the cable dress or plug bodies, which would otherwise re-emit and capacitively couple RF noise back into the cable.
Cold-welded connectors
Cold-welded connections avoid introducing heat and materials that cause distortion, such as solder. In a cold-weld process, bare copper parts are dipped in pure silver rather than tumbled in a lower-grade solution. This method creates a gas-tight connection that preserves signal integrity.
Connectors are available in banana plugs or spades, all in silver-plated red copper. The choice between bananas and spades often depends on the type of binding posts on the amplifier and speakers. Posts compliant with European standards sometimes make it difficult to tighten spade lugs with high pressure, in which case bananas are the best choice.
Permanent Molecular Optimization (PMO)
By optimally and efficiently applying a high-frequency AC signal far beyond what an audio system could deliver over any duration, transient intermodulation distortion and the cable’s break-in process are significantly reduced. This extreme treatment of dielectric materials, performed at the factory, permanently alters the insulator’s properties.
The result: the cable delivers its best performance from first use, without requiring weeks of break-in. Whereas some cables demand hundreds of hours before reaching their full potential, the Lone Ranger provides transparency and musicality immediately.
Comparison with Robin Hood
The Lone Ranger succeeds Robin Hood, a well-regarded model in the Folk Hero series. The main improvements concern the quantity 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 drain wires, whereas Robin Hood used a less elaborate shielding strategy.
These developments translate to reduced noise floor, better definition in the bass, and more precise articulation in the mids and highs. The Lone Ranger retains Robin Hood’s overall approach—solid PSC+ conductors, ZERO-Tech, 72 V DBS—while refining every aspect of the design.

Frequently Asked Questions
What’s the difference between banana plugs and spade lugs for this cable?
Banana plugs offer quick insertion and removal, particularly suited to amplifiers whose posts don’t allow for strong clamping. Spade lugs generally provide a tighter, more stable connection, but some posts compliant with European standards make their use difficult. AudioQuest offers U-spades that fit any type of post when in doubt.
Does the DBS system require a battery replacement?
The DBS module contains a battery that maintains the dielectric-bias charge. This battery lasts several years under normal use. When replacement is needed, AudioQuest supplies spare batteries and instructions to perform the operation easily.
Can I use the Lone Ranger for bi-wiring right away?
The lone Ranger alone can power a bi-wireable speaker using jumpers between the posts. For optimal bi-wiring, you’ll need to wait for the BigFoot BASS cable’s release in early 2026. This combination—Lone Ranger on the highs and BigFoot on the lows—will fully leverage compatible speakers’ capabilities. Using two Lone Ranger cables in parallel is not recommended due to possible high-frequency resonances.
Does PMO treatment make cable break-in unnecessary?
The factory-applied PMO treatment greatly reduces the usual break-in time. The cable reaches a high level of performance upon installation. Some users still report subtle improvements after a few dozen hours of use, but these changes remain minor compared to untreated cables.
How do I determine the directionality when connecting the cable?
The Lone Ranger’s conductors are directional to optimize RF noise evacuation. Clearly marked arrows on the connectors indicate the installation direction: they point from the amplifier to the speakers. This orientation, determined by listening during the manufacture of each batch of conductors, ensures optimal interference dissipation.
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 solid-state—transfer the signal to the speakers with less compression. Tube amplifiers, often sensitive to load impedance, can particularly benefit from the cable’s lack of characteristic impedance.
