QRT products are designed to improve the performance of your system, alleviating the impact of poor quality AC and DC power on your sensitive electronics, providing proper grounding, and synchronizing electromechanical resonances. The effects are cumulative and best heard when QRT products are 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.
