FiiO K13 R2R 24Bit Fully Balanced R2R DAC and Headphone Amplifier

The FiiO K13 R2R is a fully balanced desktop DAC/amp built around a proprietary four-channel, 24-bit R2R resistor-array DAC. Each channel uses 48 precision thin-film resistors (0.1% tolerance, 30 ppm temp drift) for a total of 192 resistors, delivering a rich, musical presentation with a darker, lower-noise background. Dual operating modes—NOS (non-oversampling) and OS (oversampling to 384 kHz)—let you tailor the sound, while an XMOS XU316 platform enables a 10-band PEQ you can control via the FiiO app or web interface. With a robust, fully differential amplifier stage rated at up to 2,400 mW + 2,400 mW into 32 Ω, the K13 R2R confidently drives IEMs and full-size headphones. Convenience features include Bluetooth 5.4 (LDAC/AAC/SBC) reception, an always-on HD LCD, dual-knob controls with IR remote, adjustable RGB logo lighting, and multiple protection systems—all inside a thick, unibody aluminum chassis with the new “skylight” design window.

Features

Four-channel fully differential 24-bit R2R DAC with 48 precision resistors per channel (192 total)
0.1% thin-film resistors with 30 ppm temperature drift for accuracy and stability
Fully differential signal path (DAC → LPF → volume → headphone amp) for low noise and minimal distortion
Dual modes: NOS preserves native sampling; OS upsamples globally to 384 kHz
PCM up to 384 kHz/32-bit and DSD256 native decoding
10-band high-precision PEQ (up to PCM 192 kHz/24-bit) via app or web; import/export/share EQ, Auto-EQ
Balanced output power up to 2,400 mW + 2,400 mW (32 Ω)
Three gain levels with independent volume memories for PO and PRE outputs
Bluetooth 5.4 receiver with LDAC/AAC/SBC; wired USB input via XMOS XU316
Preamp + power-amp output roles; desktop hub with versatile I/O
Always-on HD LCD for sample rate, volume, gain, and output status
Adjustable RGB logo lighting (also indicates sampling rate)
Overheat/overload protections and 1–99 minute timer shutdown
Unibody aluminum alloy chassis with “skylight” window; dual-knob control and IR remote
