FIIO K13 R2R

The FIIO K13 R2R is a desktop DAC and headphone amplifier that combines precision with a deeply musical character. At the heart of this device is a true 24-bit R2R resistor ladder DAC, built from 192 high-precision thin-film resistors in a fully balanced four-channel configuration. This classic architecture delivers a warm, natural sound with exceptional detail and realism—a more organic, analog-like listening experience that many modern delta-sigma DACs cannot match.

Listeners can choose between two playback modes: NOS (Non-Oversampling) for pure, undistorted reproduction that fully preserves the original signal, or OS (Oversampling) for a cleaner, more refined sound with added clarity. The K13 R2R's powerful amplifier section delivers up to 2,400 mW per channel at 32 Ω, effortlessly driving everything from sensitive in-ear monitors to high-impedance headphones. With three adjustable gain levels, the device easily adapts to any listening setup, whether for casual listening or critical listening.

The K13 R2R also offers plenty of connectivity options. It supports USB, coaxial, and optical digital inputs, as well as Bluetooth 5.4 with LDAC for high-resolution wireless playback. With balanced and single-ended outputs, dual USB-C ports, and a line-out, the K13 R2R is a versatile hub for modern desktop audio systems. A bright LCD screen, infrared remote control, and sturdy aluminum housing combine to create a user-friendly and elegant experience that feels as refined as it sounds.

More than just a DAC, the FIIO K13 R2R is a complete listening experience—a device that brings out the soul of your music with a perfect balance of warmth, precision, and power. Ideal for enthusiasts who want to rediscover their favorite songs with more depth, detail, and emotion—all packaged in a compact and beautifully finished design.
