Optimized for use with High/Variable-Current components (power conditioners, power amplifiers, receivers, integrated amplifiers, powered subwoofers, powered speakers), Tornado High-Current AC cable features Solid Perfect-Surface Copper+ (PSC+) conductors, 6% Silver drain wires, 72v Dielectric-Bias System (DBS), ZERO-Tech for uncompressed current transfer, and RF/ND-Tech to cancel induced RF-noise. Key Technology & Design AudioQuest markets the Tornado as a "Low-Z" (Low Impedance) cable, which focuses on noise dissipation and uncompressed current delivery. Perfect-Surface Copper (PSC & PSC+): The cable uses a blend of high-purity Solid Perfect-Surface Copper and its even higher-grade counterpart, PSC+. These conductors are designed to eliminate "strand interaction"—a major source of distortion in typical stranded cables. 72V Dielectric-Bias System (DBS): You’ll notice a battery pack attached to the cable. This creates a strong, stable electrostatic field that polarizes the insulation. The goal is to minimize energy storage in the dielectric (insulation) to prevent time-smearing and background noise. ZERO-Tech (Zero Characteristic Impedance): This technology is intended to allow for uncompressed current transfer. It is particularly effective for power amplifiers, which need to draw large, fast bursts of current during dynamic musical peaks. Ground-Noise Dissipation: It uses a patented system to drain RF (Radio Frequency) noise away from the ground wire, preventing it from entering your audio components' sensitive circuits.
