R-2R Desktop DAC & Headphone Amplifier

The FiiO K13 R2R is a desktop DAC and headphone amplifier built around a four-channel fully differential 24-bit R-2R resistor array using 192 precision resistors. It is intended for listeners who want a non-oversampling or oversampling signal path with a fully balanced analog chain from DAC through headphone output.

Who this suits and who should look elsewhere

This unit suits desktop users who need multiple digital inputs including USB-C, optical, coaxial and Bluetooth 5.4, plus flexible analog outputs via XLR balanced and dual RCA single-ended connections. It is not for buyers who require a portable battery-powered device or a purely single-ended signal path without balanced topology.

The spec that decides fit

The amplifier delivers up to 2400 mW + 2400 mW into 32 ohm loads, providing the headroom needed for demanding headphones and IEMs across low, medium and high gain settings.

Questions about this item

What desktop space does the silver FiiO K13 R2R need?

The unit is a desktop-class component designed to sit on a shelf or desk; allow room for rear USB-C, optical, coaxial and XLR/RCA cables plus front 1/4" and 4.4 mm headphone jacks.

Which input do I select first when setting up the K13 R2R?

Connect your source to USB-C, optical, coaxial or Bluetooth 5.4, then press the front input button until the matching indicator lights; the step users miss is confirming the source device outputs PCM 384 kHz or DSD256.

When should I clean the 4.4 mm balanced and 1/4" single-ended headphone sockets?

Wipe the jack openings with a dry anti-static brush whenever dust is visible; the R-2R resistor array and gain stages are sealed and need no user maintenance.
