About this item

The Fosi Audio SK02 is a compact desktop DAC and headphone amp built on the ESS SABRE ES9038Q2M chip, capable of DSD256 and 32bit/384kHz decoding with both 3.5mm and 4.4mm balanced outputs. It puts out up to 1100mW on the balanced jack and comfortably drives headphones or IEMs between 16-300 ohms, all while keeping distortion at just 0.001% THD. Beyond headphone duty, it doubles as a preamp for active speakers or paired amps, taking input over USB-C or optical from a computer, TV, or CD player. The whole unit is CNC-machined from one aluminum block with a sandblasted finish.

Built around an ESS SABRE ES9038Q2M DAC with SGM8262 op-amps, delivering 120dB SNR, 3.7μV noise floor, and 0.001% THD
Decodes DSD256 and PCM up to 32bit/384kHz, with both 3.5mm single-ended and 4.4mm balanced outputs; balanced output hits 1100mW at 32 ohms and drives headphones/IEMs from 16-300 ohms
Plug-and-play, no drivers needed — one knob handles power, play/pause, and volume, plus separate buttons for gain and input switching, with LED indicators for mode and sample rate
Takes USB-C or optical input from PCs, laptops, CD players, TVs, or projectors; works as a standalone headphone amp or as a preamp feeding active speakers or amps like the Fosi Audio V3, ZA3, or TB10D
CNC-machined from a single block of aluminum alloy with a sandblasted finish for a solid, clean look
