Alternating current (AC) is a far-from-perfect energy source. AC power technology has been around for over a century and was never designed to meet the rigorous standards of today’s high-resolution audio-video components. Noise associated with AC is present at the power source and is further exacerbated by induced radiofrequency noise (captured by the AC power cable) coupled to component power supplies and the circuit’s ground. This creates distortion and low-level signal loss through the “masking effect.” Additionally, power amplifiers may require substantial reserves of transient current for their power supplies to respond and stabilize during dynamic audio passages. Most power cables and power conditioners-regenerators, while useful to some extent, simply fall short of this task.

Power amplifiers pose a unique challenge to any AC power source, as transient current needs (though brief) can be several times greater than average current consumption (RMS). Power amplifiers also differ from other components, as their current consumption is dynamic, not constant, and changes with volume and audio signal content. While many AC power cables may exhibit low resistance to direct current to meet this requirement, the cable’s characteristic impedance is also crucial in ensuring uncompromised performance. Many high-quality AC power cables restrict or compress audio transients due to their characteristic impedance limiting transient current.


Solid conductors prevent electrical interactions between strands, a major source of distortion. Surface quality is crucial as a conductor acts as a guide for fields both inside and outside. The remarkably smooth and pure surface of all “Perfect-Surface” metals from AudioQuest virtually eliminates any roughness, significantly enhancing sound clarity compared to lower-quality materials. The meticulous selection of PSS and PSC+ conductor sizes ensures “FireBird’s” performance is close to the exclusive use of “PSS Silver,” but at a much lower cost.


U.S. Patent No. 8,988,168. AC ground wires do provide protection against electrical short circuits, but they also act as an antenna. Therefore, they are prone to induced radiofrequency (RF) noise. This RF noise bypasses component power supplies and is usually directly coupled to the most sensitive audio-video circuits in an audio-video system. AudioQuest’s patented RF/ND technology significantly reduces this distortion, allowing unprecedented noise dissipation levels across the widest possible radiofrequency bandwidth. Our unique circuit topology employs a common-mode phase-suppression network, along with proprietary dielectric materials providing additional linear differential filtering.


While many AC power cables exhibit low resistance to direct current (DC) to meet high current demand, a cable’s characteristic impedance is also crucial for optimal performance. Unlike most AC cables that restrict or compress audio-induced transients, AudioQuest’s AC cables combine low DC (direct current) resistance and a ZERO characteristic impedance to deliver uncompressed high-current transients on demand.


All insulation is a dielectric whose electrical properties affect signal integrity. When insulation is unbiased, dielectric involvement (non-linear absorption and release of energy in the signal flow) causes different amounts of time delays (phase shifts) for different frequencies and energy levels, a significant problem for multi-octave audio signals highly sensitive to time. AudioQuest’s patented DBS system creates a strong and stable electrostatic field that saturates and polarizes (organizes) the insulating molecules. This minimizes non-linear delays, allowing for clearer sound emerging from a “blacker” background. The Level-X RF trap (technology developed for AudioQuest’s “Niagara” power product series) in the DBS battery pack “pulls” RF noise out of the cable, preventing RF from infiltrating the electronics. The DBS pack batteries have a lifespan of about 10 years. Use the test button to check their status.


All audio cables are directional. The correct orientation is determined by listening to each batch of metal conductors used in every AudioQuest audio cable. The direction of audio digital signal conductors is controlled in AudioQuest’s HDMI cables, and we even take care to lay out Audio Return Channel (ARC) conductors in the opposite direction to ensure optimal performance of this function. Arrows are prominently displayed on the connectors to ensure optimal sound quality.
