FiiO DARKSIDE PRO Linear Power Supply for Sensitive Hi-Fi Audio Components
FiiO DARKSIDE PRO is a linear power supply designed for sensitive Hi‑Fi components, targeting audible improvements through ultra‑clean, low‑noise power delivery.
It offers switchable 12 V or 15 V output with up to 3 A current, ensuring stable power reserves for DACs, streamers, preamps, and headphone amplifiers.
The design centers on a 75 W toroidal transformer, chosen for high efficiency and minimal magnetic leakage, reducing high‑frequency interference common in switching supplies.
