Low-Z / Noise-Dissipation 3-Pole AC Power Cable Solid Perfect-Surface Copper+ (PSC+) Perfect-Surface Copper (PSC) Conductors Optimized For Source Components RF/ND-Tech (US Patent # 8,988,168) ZERO (No) Characteristic Impedance (50Hz – 1MHz) 72v 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 the circuit ground. This creates distortion and low-level signal losses via the “masking effect.” Most AC power cords and power conditioner-regenerators, though helpful to a point, are simply not up to the task.Note: AudioQuest Tornado/Source AC power cable is not appropriate for use with AC power conditioners, power regenerators, AC isolation transformers, AC battery back-up devices, as well as any power amplifier, powered subwoofer, powered loudspeaker, powered receiver, or integrated amplifier (whether tube, solid state or digital switching). These products will require greater RMS and transient current capacity. In extreme instances, they could suffer diminished performance and/or present an electrical danger by exceeding the AudioQuest Dragon/Source AC power cable’s maximum current capacity. For those applications, we highly recommend selecting the AudioQuest’s Dragon/High-Current AC power cable.
