AudioQuest Brave Heart Full-Range Speaker Cable

About The AudioQuest Brave Heart Full-Range Speaker Cable

Featuring tried-and-true AudioQuest design elements along with ZERO-Tech for no characteristic impedance, Brave Heart has significantly more conductor metal than its predecessors while being more physically manageable thanks to its positive and negative sides being housed in separate round constructions. The result is a quieter cable that delivers the torque and bottom-end grip of a larger model. 

Simply put, Brave Heart is bigger, quieter, and better than any speaker cable AudioQuest has previously offered at or near its price. There are a number of technical details, both external and internal, that contribute to Brave Heart's outstanding combination of performance and value.

Physically, Brave Heart is nearly the size of AudioQuest's Mythical speaker cables, just 0.6mm smaller OD. Internally, it has almost a third more of the same superb Perfect-Surface Copper+ conductor metal as used in previous models, making it a slightly junior Mythical Creature. Yet, Brave Heart is more physically manageable because it houses positive and negative sides in separate round constructions.

Brave Heart's larger overall size results in more “torque” - a sure and muscular grip on the music, especially the bottom end. Damping-factor is better preserved over length, especially benefitting speakers with very low impedance at some (often bass) frequencies. It also produces a flatter frequency response because more metal means that variation in speaker-impedance values across the frequency spectrum has less effect on frequency response.

With conductors that are farther apart thanks to more insulation, the out-of-focus effect of conductor-to-conductor magnetic interaction is meaningfully reduced. Finally, thicker layers of Carbon-Loaded PVC, newly added Graphene, and 4% silver shield drain wires further improves RF-Noise Dissipation.

All this, plus a wealth of proven AudioQuest design elements: Solid conductors prevent strand interaction, and, because the conductors are direction-controlled, RF noise is efficiently dissipated away from the active circuit - in the direction of least harm. To further minimize the negative effects of induced RF-noise and timing errors due to dielectric noise, Brave Heart includes AudioQuest's 72v Dielectric-Bias System. There is no RF-relaying metal in the cable dressing, breakouts, or plug barrels, and the cold-welded gas-tight connections are made to Red Copper spades or bananas.

While a grossly overused and misused term, there is real synergy when all the above materials, values, and techniques employed in Brave Heart work in concert. Brave Heart is bigger, badder, better than AudioQuest has ever offered at this price.

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 linearized (consistent octave to octave).

Solid Perfect-Surface Copper+ Conductors (PSC+): High-purity PSC+ conductors prevent strand interaction, a major source of ear-fatiguing transient intermodulation distortion. The astonishingly smooth and pure PSC+ further eliminates harshness and greatly increases clarity compared to OFHC, OCC, 8N and other premium coppers.

Level 7 Linear Noise-Dissipation: The Earth is permeated with RF-Noise from satellites, cellular, Wi-Fi, etc. Brave Heart’s Graphene+Carbon Mesh-Network, ZERO-Tech, direction-controlled metal, 72v DBS, and silver-plated 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.

4% Silver Shield Drains: Significantly aid in the efficient dissipation of RF-Noise.

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 properly.

Our Review

AudioQuest’s Brave Heart speaker cable is a bold statement in performance and value, offering an impressive blend of muscle, finesse, and thoughtful design. It’s a cable that’s physically substantial—almost the size of AudioQuest’s top-tier Mythical models - but with a friendlier, more flexible layout thanks to its separate round cables for positive and negative runs. That clever approach makes it easier to handle, while the additional conductor mass - nearly a third more Perfect-Surface Copper+ than earlier generations - results in a deeper grip on the music. The bass gains noticeable authority, the mids breathe more freely, and transients arrive with uncompressed ease, all while remaining whisper-quiet thanks to smart noise-dissipation tricks like the 72v Dielectric-Bias System and a mesh of carbon, graphene, and silver shielding.

At its core, Brave Heart is packed with tech that reads like an audiophile wish list. AudioQuest’s ZERO-Tech eliminates characteristic impedance, letting current flow cleanly and consistently from amp to speaker. That means dynamics feel more immediate and powerful, especially when dealing with speakers that dip into tricky low-impedance territory. RF noise - a growing issue in our wireless world - is tamed through a multi-layered strategy, with everything from directional solid-core PSC+ conductors to cold-welded red copper terminations working together to preserve clarity and timing. While the name might sound heroic, Brave Heart isn’t just for show - it’s a carefully engineered performer that delivers genuinely big-league sound without crossing into mythical pricing territory.
