AudioQuest Brave Heart Full-Range ZERO-Tech Speaker Cable

The AudioQuest Brave Heart Full-Range Speaker Cable delivers exceptional power, resolution, and noise control at a breakthrough value. Designed by AudioQuest, Brave Heart features solid Perfect-Surface Copper+ (PSC+) conductors with nearly one-third more copper than previous models for lower impedance, improved damping factor, and a stronger grip on bass performance—especially with low-impedance or ported speakers. ZERO-Tech eliminates characteristic impedance for unrestricted current transfer and enhanced transient response, while the 72v Dielectric-Bias System (DBS) reduces dielectric noise and linearizes RF noise dissipation. Upgraded polypropylene insulation, carbon-loaded PVC, a graphene layer, and 4% silver shield drain wires further minimize distortion and external interference. Positive and negative conductors are housed in separate round constructions for reduced interaction and improved clarity. Finished with cold-welded, gas-tight red copper spades or banana plugs, Brave Heart offers dynamic authority, expansive soundstaging, and refined detail for high-performance two-channel and home audio systems.
