Tornado / High-Current

Low-Z / Noise Dissipation 3-pole power cable

  • Solid Perfect-Surface Copper + (PSC +) Conductor made of Perfect-Surface Copper (PSC)
  • Uncompressed high current transmission
  • Ground Noise Dissipation Technology (US Patent No. 9,373,439)
  • NULL (No) characteristic impedance (50Hz - 1MHz)
  • 72 VDC dielectric bias system (US Patent No. 7.126.055)
  • Directional ladder

Alternating current (AC) is not a perfect power source. AC technology is well over a century old and has never been developed to meet the high standards of today's high-definition audio-video components. AC interference occurs at the power source and is amplified by radio frequency interference induced (picked up) by the AC cable and connected to the component power supplies and circuit ground. This leads to distortions and signal losses at low levels via the "masking effect". In addition, power amplifiers can require enormous reserves of transition current so that their power supplies can react to dynamic audio passages and then stabilize. Most power cables and power regenerators are helpful up to a certain point, but simply not suitable for this task.

Power amplifiers are a real challenge for any AC power source, as the transition current requirements (although short-lived) can be many times the average power consumption (RMS). Power amplifiers also differ from all other components in that the current consumption is dynamic and not constant and changes with the volume and the audio signal. Although many AC cables may have low DC resistance to meet some of these requirements, the characteristic impedance of the AC cable is equally responsible for ensuring uncompromising performance. Many premium AC cables constrict or compress the audio transient because their characteristic impedance limits the transient current.

Features & Benefits


A carefully engineered combination of solid high purity Perfect-Surface Copper (PSC) and extremely high purity Perfect-Surface Copper + (PSC +) to prevent strand interactions, a major cause of ear fatigue in transient intermodulation distortion. The amazingly smooth and pure copper with perfect surface eliminates hardness and significantly increases clarity compared to OFHC, OCC, 8N and other premium copper grades. The superior purity of PSC + further minimizes the grain boundary distortion present in a metal conductor.


AC grounding cables provide protection against power wiring faults, but also act as antennas. Therefore, they are exposed to induced high frequency noise (RF noise). This RF noise bypasses component power supplies and is normally coupled directly into the most sensitive audio/video circuits of a system. AudioQuest's patented ground noise dissipation significantly reduces this distortion and results in unprecedented noise dissipation over the widest possible bandwidth (range) of radio frequencies. Our unique circuit topology uses a common mode phase compensation array in conjunction with proprietary dielectric materials that provide additional differential linear filtering. (US Patent No. 9,373,439)


Any insulation between two or more conductors is also a dielectric whose properties affect the integrity of the signal. If the dielectric is undistorted, the inclusion of the dielectric (absorption and nonlinear release of energy) causes a different time delay (phase shift) for different frequencies and energy levels, which is a real problem for very time-sensitive multi-octave audio. The use of an RF trap (developed for AudioQuest's Niagara series) ensures that no RF interference is induced from the DBS field elements into the signal conductors. (DBS, US Patent No. 7.126.055 and 7.872.195 B1)


With a current capacity of 20 A RMS at 125 VAC (50/60 Hz) (16 A RMS at 220-240 VA (50/60 Hz)) Tornado / High (Variable) Current transient peaks can withstand a multiple of its continuous (average) RMS value. This makes Tornado / High (Variable) Current ideal for a wide range of AC conditioners, current regenerators, AC isolating transformers and AC battery fuses, as well as all power amplifiers, active subwoofers, active speakers and active receivers or integrated amplifiers.


All drawn metal strands or conductors have a non-symmetrical and therefore directed grain structure. AudioQuest adjusts the resulting change in RF impedance so that noise is removed at the point where distortion occurs. The correct direction is determined by listening to all metal conductors used in each AudioQuest audio cable. If applicable, the arrows on the connectors are clearly marked to ensure excellent sound quality. On most AQ cable models, the arrows indicate not only the direction that optimizes the metal directivity as part of noise dissipation, but also the unbalanced attachment of shield and GND to optimize the performance of the entire system.
