Brave Heart ZERO
AudioQuest is delighted to introduce its newest ZERO-Tech speaker cable, Brave Heart — bigger, quieter, and altogether better than any speaker cable AQ has offered at 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.
Bigger
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 ported (4th-order) enclosures that rely on strong amplifier control to perform their best.
More metal also means that variation in speaker impedance values across the frequency spectrum has less effect on frequency response.
Quieter
Brave Heart also uses upgraded polypropylene insulation, which linearizes and expands the bandwidth of its noise-dissipation. With conductors that are farther apart thanks to optimized insulation, the out-of-focus, harsh-sounding effect of distributed capacitance distortions are meaningfully reduced.
Additionally, thicker layers of Carbon-Loaded PVC, newly added Graphene, and 4% silver shield drain wires further improves RF-Noise Dissipation.
