About the PowerQuest 303
The AudioQuest PowerQuest 303 is a high-performance power conditioner designed for HiFi audio and video systems, featuring advanced linear noise-dissipation technology that reduces differential-mode noise by more than -22dB from 30kHz to 1GHz. It provides non-sacrificial surge protection capable of withstanding multiple 6000V/3000A surges and includes Extreme Voltage Shutdown that activates at 140V with a response time under 0.25 seconds, auto-resetting when safe. With 12 optimized AC outlets—4 high-current for receivers, amps, soundbars, and subs, and 8 linear-filtered for sources like TVs, streamers, and computers—it supports a maximum current of 15A RMS at 120V. Rack-mountable in 2U space with included brackets, it comes with a detachable 2m (6.5ft) PQ-415 direction-controlled power cable using Semi-Solid Concentric Long-Grain Copper conductors and flat-to-wall plug. Ideal for stereo systems, home theaters, and custom installs, it enhances audio clarity and protects equipment without current compression.
