AudioQuest Firebird High-Current

The AudioQuest Firebird High-Current is a Low-Z / Noise-Dissipation 3-Pole AC Power Cable.

  • Solid Perfect-Surface Silver (PSS)/Perfect-Surface Copper+ (PSC+) Conductors
  • Uncompressed High-Current Transfer
  • Ground Noise-Dissipation Technology (US Patent # 9,373,439)
  • ZERO (No) Characteristic Impedance (50Hz – 1MHz)
  • Dielectric-Bias System with Radio Frequency Noise Trap
  • Directionally Controlled Conductors

Alternating Current (AC), is a far-from-perfect power source. AC power technology is well over a century old and was never designed to meet the exacting standards of today’s high resolution audio-video components. AC noise is present at the utility source, and is then exacerbated by radio frequency noise that is induced (picked up by the AC power cord) and coupled to the component power supplies and to circuit ground. This creates distortion and low-level signal losses via the “masking effect.” Further, power amplifiers can require immense reserves of transient current for their power supplies to react to and then stabilize during dynamic audio passages. Most AC power cords and power conditioner-regenerators, though helpful to a point, are simply not up to the task.

Power amplifiers present a real challenge for any AC power source, as the transient current requirements (though short in duration) can be many times that of the average (RMS) current consumption. Power amplifiers are also unique from all other components in that the current draw is dynamic, not constant, and it changes with volume and audio signal content. Though many AC power cords may feature low DC resistance to allow for some of this requirement, the characteristic impedance of the AC cable is equally responsible for assuring uncompromised performance. Many premium AC cords constrict or compress the audio transient as their characteristic impedance restricts the transient current.

AC Ground wires provide protection from current-wiring faults, but they also act as antennas. Thus, they are subject to induced radio-frequency (RF) noise. This RF noise bypasses component power supplies and is typically coupled directly into a system’s most sensitive audio/video circuits. AudioQuest’s patented Ground-Noise Dissipation (GND) greatly reduces this distortion, yielding unprecedented levels of noise dissipation across the widest bandwidth (range) of radio frequencies possible. Our unique circuit topology utilizes a common-mode phase-cancelling array, in concert with proprietary dielectric materials which provide additional differential linear filtering.
