DARKSIDE PRO Low-Noise Regulated Linear Power Supply Is Officially Released!

In 2025, FIIO planned many new products. Now, with 2026 Chinese New Year fast approaching, most of these new products have already entered mass production and are available on the market. While a few haven't been released yet, they are expected to be launched before March 31, 2026, in accordance with FIIO's fiscal year. And today, we celebrate the official launch of the DARKSIDE PRO linear power supply.

DARKSIDE PRO lives up to its name by providing an ultra-silent, pitch-black background, letting the true essence of your music shine through.

With a 75W reserve, it effortlessly handles high-dynamic transient demands, delivering solid bass extension and a vividly clear soundstage.

An integrated relay manages the transformer’s output voltage to provide a precise match for both 12V and 15V settings. Such a design maximizes power efficiency and significantly reduces heat generation during operation.

Dual high-current IRFZ34NPBF MOSFETs are used in a parallel configuration to lower internal resistance. The result is improved dynamic range and ensures that every nuance of the audio is faithfully preserved.

Precision potentiometer for voltage fine-tuning: Allows for granular adjustments to perfectly match your specific requirements.

Shipments from distributors will be arranged after the Spring Festival holiday. If you want to buy from a local distributor, please wait until March 2026):
