FiiO Darkside Pro - Black - Silver

Description

Revealing the True Potential of Your Audio System

Often overlooked, power delivery plays a critical role in overall system performance. The Darkside Pro is designed to address one of the most common limitations in modern audio setups: noisy switching power supplies. By replacing standard adapters with a carefully engineered linear power design, it minimizes electrical interference and provides a stable foundation for high-resolution playback. The result is not a change in tonal balance, but a refinement in presentation—greater transparency, improved detail retrieval, and a more natural sense of dynamics.

Audiophile-Grade Power Architecture

At the core of the Darkside Pro is a high-capacity 75W toroidal transformer, specifically engineered to reduce magnetic leakage and ensure efficient, low-noise operation. Its design allows for strong current reserves, supporting dynamic musical passages without compression or strain.Complementing this is a fully discrete NMOS voltage regulation circuit with dual MOSFET output stages, delivering precise voltage control with minimal ripple and ultra-low noise performance.

Ultra-Low Noise, “Pitch-Black” Background

FiiO’s goal with the Darkside Pro is simple: remove unwanted noise from the power chain. By significantly lowering the noise floor, it enables connected components to operate closer to their intended performance, revealing finer details and improving overall system stability. This translates into tighter bass control, cleaner transients, and a more defined soundstage—enhancements that become increasingly noticeable in resolving systems.

Flexible Output for System Integration

The Darkside Pro offers switchable 12V and 15V output modes, making it compatible with a wide range of audio devices, including DACs, headphone amplifiers, and network streamers. With up to 3A of current delivery, it ensures sufficient power for demanding components without compromising stability. A precision voltage adjustment system allows fine-tuning within tight tolerances, ensuring optimal matching with connected equipment.

Premium Components and Thoughtful Design

Every aspect of the Darkside Pro reflects its audiophile positioning. High-quality capacitors from ELNA, Rubycon, and WIMA are used for effective filtering, while a robust aluminum chassis provides durability and shielding against interference. User-friendly features such as a voltage selector, LED display, and protective circuitry—including over-current protection and a self-resetting fuse—ensure both ease of use and long-term reliability.
