The FiiO DARKSIDE PRO is an adjustable low-noise linear power supply specifically designed for audiophile-grade audio devices. As part of FiiO's Power Purification series, the DARKSIDE PRO power supply delivers ultra-low noise performance, allowing the true character of the music to shine through with unmatched clarity and detail.

Based on a toroidal 75W power supply manufactured with a circular iron grain core process, the DARKSIDE PRO minimizes current surges, reduces magnetic interference, and provides a smooth, ripple-free winding structure for a perfectly uniform magnetic field. The 75W capacity sufficiently matches the high dynamic demands of audio signals, offering a cleaner and more dynamic listening experience.
