FiiO Darkside Pro Low-noise regulated linear power supply (Silver)

75W Toroidal Transformer - Specifically designed for low-noise audio, this toroidal transformer utilises a grain-oriented silicon steel circular core process for higher efficiency and minimised eddy currents. The seamless, fold-free coil design ensures a uniform magnetic field and minimal magnetic leakage. With a 75W reserve, it effortlessly handles high-dynamic transient demands, delivering solid bass extension and a vividly clear soundstage. Fully Discrete NMOS Voltage Regulator Circuit - Dual high-current IRFZ34NPBF MOSFETs are used in a parallel configuration to lower internal resistance. The result is improved dynamic range and assurance that every nuance of audio is faithfully preserved. Relay-Switched 12V/15V Output - An integrated relay manages the transformer's output voltage to provide a precise match for both 12V and 15V settings. Such a design maximises power efficiency and significantly reduces heat generation during operation.
