THE TASK

Alternating current (AC) is anything but the perfect power source. AC technology is more than a hundred years old and has never been designed to meet the requirements of today's high-definition audio-video components. AC noise comes from the power source, is amplified by high-frequency noise picked up by the power cord, and reaches the power supplies of the components and the ground of the circuit. This creates distortion and signal losses at low levels due to the "masking effect". In addition, power amplifiers can require large reserves of peak currents so that their power supplies can react quickly during dynamic audio passages and then stabilize. Although most power cables, power conditioners and regenerators bring a certain amount of improvement, they are ultimately not up to the task.

Power amplifiers pose a real challenge to any AC power source, as peak power requirements (even if short-lived) can be many times the average (RMS) power consumption. Power amplifiers differ from all other components in that the power consumption is not constant but dynamic; it varies depending on the volume and content of the audio signal. Many power cords have a low DC resistance to meet some of these requirements, but the characteristic impedance of the power cord is equally responsible for ensuring smooth playback. In many premium power cables, audio pulses are cut or compressed because current peaks are cut by their characteristic impedance.

THE SOLUTION

High-purity conductors: The Tornado/High-Current uses a carefully matched combination of solid conductors of Perfect-Surface Copper (PSC) and extremely high-purity Perfect-Surface Copper+ (PSC+) to prevent mutual interference between individual strands and thus a major cause of transient intermodulation distortion leading to hearing fatigue. The amazingly smooth and pure Perfect-Surface Copper eliminates roughness and significantly improves transparency compared to OFHC, OCC, 8N and other premium copper grades. The exceptional purity of PSC+ also reduces distortion caused by the constrictions present in any metal conductor.

Uncompressed high current transmission: With a current delivery capability of 20 A RMS at 125 VAC 50/60 Hz (16 A RMS at 220 - 240 VA 50/60 Hz), the Tornado/High-Current can withstand current peaks many times the continuous (average) RMS power. This predestines the Tornado/High-Current for use on a wide range of mains power conditioners, regenerators, AC isolating transformers and AC battery backup devices as well as any power amplifiers, active subwoofers, active loudspeakers, A/V receivers and full amplifiers.

Ground Noise Dissipation Technology: AC ground conductors provide protection from the flaws in network wiring, but they also act as antennas. Therefore they are subject to the influence of high frequency noise (HF). This RF noise bypasses the component power supplies and is typically routed directly to the most sensitive audio-video circuits in a system. AudioQuest's patented Ground Noise Dissipation greatly reduces distortion and delivers an unprecedented level of noise dissipation over the widest possible high frequency bandwidth. In our unique circuit topology, a common mode phase cancellation arrangement is used in conjunction with proprietary dielectric materials to provide additional linear differential filtering.

Dielectric-Bias System (DBS; US Pat #7,126,055): By generating a stable dielectric field for the primary capacitance range or dielectric of the cable, the DBS ensures extended bandwidth and more uniformly filtered noise dissipation, eliminating distortions and overshoots that continue to cause dissatisfaction with other cables even after years of use and so-called break-in time. In addition, the DBS ensures that the HF noise dissipation system operates as linearly as possible.

Controlled directionality: All drawn metal strands and conductors have an asymmetrical and therefore directional grain structure. The resulting changing RF impedances are controlled by AudioQuest in such a way that the noise is diverted from where it would cause distortion.
