Audioquest Brave Heart Full-Range ZERO-Tech Speaker Cable

The AudioQuest Brave Heart pushes performance and value to a new level, taking proven AudioQuest design principles and enhancing them with cutting-edge ZERO-Tech for no characteristic impedance. Compared to its predecessors, Brave Heart contains significantly more Perfect-Surface Copper+ conductor metal while remaining more manageable thanks to its dual round-construction design. The result is a cable that’s bigger, quieter, and more powerful—delivering the torque and bottom-end grip of larger models at a more attainable price.

Physically, Brave Heart approaches the size of AudioQuest’s flagship Mythical Creature series, yet remains slightly slimmer and easier to handle. Internally, it boasts nearly a third more conductor metal than previous generations, giving it the authority and control of a “junior Mythical Creature.” By housing positive and negative conductors in separate round constructions, Brave Heart enhances damping-factor preservation, ensuring tight, muscular bass performance and exceptional amplifier control across even the most demanding loudspeakers.

Noise management is taken further with upgraded polypropylene insulation, optimized conductor spacing, Carbon-Loaded PVC, newly integrated Graphene, and silver-plated shield drains—all contributing to superior RF-noise dissipation. Combined with AudioQuest’s advanced 72v Dielectric-Bias System, solid direction-controlled PSC+ conductors, and cold-welded red-copper terminations, Brave Heart achieves remarkable clarity, dynamics, and linearity across the frequency spectrum.

This synergy of materials and design techniques culminates in a cable that’s simply bigger, badder, and better than anything AudioQuest has ever offered at this price.

Key Features

• ZERO-Tech (No Characteristic Impedance): Eliminates mismatch effects, enabling uncompressed current transfer and linearized RF-noise dissipation.
• Solid Perfect-Surface Copper+ Conductors (PSC+): High-purity copper conductors prevent strand interaction and reduce distortion, delivering superior clarity and smoothness.
• Level 7 Linear Noise-Dissipation: Graphene+Carbon Mesh, ZERO-Tech, 72v DBS, silver shield drains, and direction-controlled metal minimize RF interference.
• 72v Dielectric-Bias System (DBS): Biasing the dielectric minimizes dielectric noise, expanding bandwidth and improving wide-bandwidth dissipation of induced noise.
• 4% Silver Shield Drains: Efficient RF-noise dissipation for greater musical resolution.
• Cold-Welded Red-Copper Spades or Bananas: Gas-tight connections without distortion-causing solder. Non-metal plug casings further prevent RF interference.
• Direction-Controlled Conductors: Ensures noise is drained away from sensitive circuitry for lower distortion and improved performance.
