FiiO K11 R2R Desktop DAC & Headphone Amplifier – Black

The FiiO K11 R2R brings the warm, natural, analog-like sound of a true R2R resistor-ladder DAC to your desk in a compact, affordable package. At its heart is FiiO's self-developed, four-channel, fully differential 24-bit R2R DAC, built from 192 precision thin-film resistors with 0.1% tolerance and low 30ppm temperature drift.

Up to 1300mW + 1300mW of balanced power, three gain levels, and switchable NOS/OS modes let the K11 R2R drive everything from sensitive IEMs to demanding headphones up to 350Ω, while USB, optical, and coaxial inputs plus RCA line output make it the center of any desktop system.

Key Features

  • Fully differential true 24-bit R2R DAC with 192 precision thin-film resistors
  • Switchable NOS (non-oversampling) and OS (oversampling up to 384kHz) modes
  • USB decoding up to PCM 384kHz/32-bit and native DSD256
  • Up to 1300mW + 1300mW (32Ω) from the 4.4mm balanced output
  • 6.35mm single-ended and 4.4mm balanced headphone outputs
  • USB Type-C, optical, and coaxial digital inputs; RCA line output
  • NJW1195A electronic volume control with three gain levels and independent volume curves
  • FPGA-processed digital audio bridge and SGM8262 output stage
  • 17 low-noise LDO regulators and high-quality solid-state capacitors
  • High-contrast LCD display, multi-function volume knob, and adjustable RGB logo light

True R2R Sound

Unlike conventional delta-sigma chips, the K11 R2R converts audio through a discrete resistor ladder, delivering a smooth, textured, and natural presentation loved by listeners seeking an analog feel.

Power for Your Headphones

The amplifier stage pushes 1300mW per channel balanced into 32Ω, with three gain settings so you can pair it with sensitive IEMs or power-hungry full-size headphones.

Protected and Clean

A carefully designed low-noise power supply, headphone protection circuitry, and pop-noise elimination keep your audio clean and your headphones safe.
