Nordost’s QRT power products are designed to alleviate the impact of poor quality AC power on your sensitive electronics. By controlling ground flow, and limiting RFI and timing errors associated with the AC line, QRT products bring AC power closer to the desired “distortion-less condition” without limiting the peak current of your electronics.

QRT products are cumulative and their effects are best heard when used as a system. When arranged correctly, the effects include a lower noise floor, increased image depth with tighter focus, wider soundstage, as well as improved overtones, pacing, dynamic range and musical expression.
