FiiO Darkside Pro Low-Noise Regulated Linear Power Supply, Silver Overview

View this description in German

The FiiO Darkside Pro is a premium linear power supply for listeners building a cleaner, quieter HiFi setup. Its 75W toroidal transformer provides plenty of power in reserve, helping connected equipment respond confidently to dynamic musical passages while supporting clear sound and solid bass extension.


A fully discrete NMOS voltage regulator keeps output noise extremely low, giving your DAC, amplifier, or streamer a cleaner power foundation so subtle details are easier to hear. You can switch between 12V and 15V output to accommodate a range of compatible FiiO equipment. There's also precision voltage adjustment, helping you fine-tune the output to suit your connected device.


Meanwhile, carefully selected ELNA, Rubycon, and WIMA capacitors help filter unwanted power noise. Everything sits inside a sturdy aluminium chassis designed to reduce resonance and electromagnetic interference, with cooling grilles helping maintain stable operation during longer listening sessions.
