The Fosi Audio SK02 is a premium desktop DAC and headphone amplifier that combines elegant minimalist design with exceptional audio performance. Featuring the acclaimed ESS SABRE ES9038Q2M DAC chipset, it delivers studio-grade sound with a remarkable 120dB signal-to-noise ratio and virtually imperceptible distortion at just 0.001% THD. This versatile device handles high-resolution audio up to DSD256 and PCM 32-bit/384kHz, while its balanced 4.4mm output generates 1100mW of power—sufficient to drive virtually any headphone or IEM from 16 to 300 ohms with authority. The intuitive interface features a responsive multi-function knob and quick-access gain switches, with intelligent indicator lights displaying input mode and sample rate. Beyond headphone amplification, the SK02 functions as a preamp for active speakers or integrated amplifiers, making it an ideal foundation for a high-fidelity desktop or compact home audio system. Built from precision-machined aluminum and backed by a comprehensive 24-month warranty, this plug-and-play solution requires no driver installation and accepts both USB and optical inputs for seamless integration with computers, media players, and video sources.
