About the K11
The FiiO K11 is a compact desktop digital-to-analog converter and headphone amplifier based on the Cirrus Logic CS43198 DAC. It supports high-resolution PCM audio up to 384 kHz/32-bit and native DSD256 over USB. Connectivity includes USB Type-C, optical, and coaxial digital inputs, while outputs include 4.4 mm balanced and 6.35 mm single-ended headphone connections, RCA line out, and coaxial digital out when operating in USB mode. The unit provides three gain levels, three volume curves, a custom LCD display, and adjustable RGB logo lighting. The K11 is distinct from the later K11 R2R, which uses a different R2R DAC architecture and lower rated output power.
