High-end audio equipment is designed to produce the highest quality sound possible. The power supply is an essential component of any electronic device, and providing a clean, stable power source can greatly improve the overall performance of the audio equipment. High-quality AC power can help reduce electrical noise and distortion, which can negatively affect the sound quality. Additionally, power supplies in high-end audio equipment often use specialized components that require a specific range of voltage and frequency to function properly. Using a high-quality power source can help ensure that these components are operating within their specified parameters, further improving the sound quality.
