AudioQuest Brave Heart Full-Range ZERO-Tech Speaker Cable

High-purity PSC+ full-range speaker cable with ZERO-Tech geometry, Level-7 noise dissipation, and 72 V DBS

Brave Heart takes several of AudioQuest’s proven design principles and scales them up, combining significantly more conductor metal with a physically manageable form factor. By housing the positive and negative legs in separate round constructions, the cable reduces interaction, lowers noise, and maintains flexibility despite its size.

With nearly a third more Perfect-Surface Copper+ (PSC+) than the previous generation and an outer diameter just 0.6 mm shy of the Mythical Series, Brave Heart delivers a level of grip, control, and dynamics that place it just beneath AudioQuest’s top tier. Its larger conductor mass helps preserve amplifier damping factor over length, especially benefitting low-impedance loudspeakers and ported designs that demand authoritative current delivery.

Brave Heart also incorporates upgraded polypropylene insulation, wider conductor spacing, newly added Graphene, and thicker Carbon-Loaded PVC layers to meaningfully improve wide-band noise dissipation. Combined with direction-controlled conductors, 4% silver drains, cold-welded terminations, and the 72 V Dielectric-Bias System, the result is a quieter, more linear cable capable of uncompressed transient current transfer.
