Mains Filters & Power Conditioning

Clean power — the foundation you don't see but can hear

A mains filter or power conditioner is a device that frees your hi-fi system from disturbances on the mains and supplies it more stably. Amplifiers and streamers are only as good as the power they get: mains filters clean the incoming line, power conditioners additionally distribute and stabilise the energy. The result is often a quieter background, more fine detail and a more stable sound picture — this really shows, especially in older house wiring or when many devices share one circuit.
