PowerQuest Delivers
Alberto Pittaluga dives deep into the benefits of power conditioning, explores the relatively modest PowerQuest 3, and decides it’s staying in his system.
Power Cable
Often, the choice between terminating your speaker cables with spade lugs or banana plugs will come down to personal preference. However, the EU-compliant isolated binding posts used on some power amplifiers often makes it difficult if not impossible to tighten spade lugs with high torque or pressure. In these applications, the AudioQuest banana connector is the superior choice, and may be the only choice.
AudioQuest has conducted a fairly extensive survey of contemporary amplifier manufacturers to determine whether spades or bananas will be most appropriate for a given brand and model of amplifier. Please contact us, provide the brand and model of the amplifier, and we’ll respond with the optimal connector type.
Here we typically recommend the U-Spade or banana connector. However, even though there is less weight and pressure on this side of the cable (particularly for BiWire sets), it is nevertheless important to note the binding post’s design. If a banana connector cannot seat all the way into the binding post, we recommend one of our spade connectors.
Constant-Current (Source) Cables
Optimized for use with audio/video source components, which have a constant or “fixed” current draw.
Perfect-Surface Copper (PSC) and Perfect-Surface Copper+ (PSC+) Conductors
A carefully finessed combination of solid high-purity Perfect-Surface Copper (PSC) and extreme high-purity Perfect-Surface Copper + (PSC+) conductors to prevent strand interaction, a major source of ear fatiguing transient intermodulation distortion. The astonishingly smooth and pure Perfect-Surface Copper eliminates harshness and greatly increases clarity compared to OFHC, OCC, 8N and other premium coppers. The superior purity of PSC+ further minimizes distortion caused by grain boundaries, which exist within any metal conductor.
ZERO-Tech
While many AC power cables feature low DC resistance in order to accommodate the demand for high current, a cable’s characteristic impedance is also crucial for optimal performance. Unlike most AC cables that constrict or compress an audio-provoked transient, AudioQuest AC cables combine low DC resistance and ZERO (no) characteristic impedance in order to deliver uncompressed high-current transients on demand.
RF/ND-Tech
AC Ground wires may provide protection from an electrical short circuit, but they also act as an antenna. 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 RF/ND-Tech greatly reduces this distortion, yielding unprecedented levels of noise dissipation across the widest bandwidth (range) of radio frequencies possible. Our unique circuit topology uses a common-mode phase-cancelling array, in concert with proprietary dielectric materials which provide additional differential linear filtering. US Patent # 8,988,168.
72v Dielectric-Bias System (DBS)
Insulation is also a dielectric that can act like a shunt-filter. Biasing minimizes dielectric-noise and linearizes the filter, significantly improving wide-bandwidth dissipation of induced RF noise.
Directionality
All drawn metal strands or conductors have a non-symmetrical, and therefore directional, grain structure. AudioQuest controls the resulting RF impedance variation so that noise is drained away from where it will cause distortion. The correct direction is determined by listening to every batch of metal conductors used in every AudioQuest audio cable. When applicable, arrows are clearly marked on the connectors to ensure superior sound quality. For most models of AQ cable, the arrows not only indicate the direction that optimizes metal-directionality as part of Noise-Dissipation, but also indicates non-symmetrical attachment of shield and GND in order to optimize full-system performance.
