WARMER R2R

Go for a bolder flavor

The ultimate warm-sounding setup

The WARMER R2R draws its inspiration from

the legacy of the timeless Hong Kong band, the Wynners.

As its name suggests, the WARMER R2R DAC aims to infuse music

with an invitingly warm and beautiful tube sound.

From the mesmerizing sway of the vintage warm-hued VU meters to the golden pairing of R2R DAC and vacuum tubes, the WARMER R2R lets you sense the warmth of the music during every listening session.

Basic specifications

Uniquely captivating

Proprietary fully differential true

24Bit R2R resistor arrays DAC

The star of the show is FIIO’s proprietary, four-way fully differential 24-bit R2R DAC, built with a total of 192 high-precision thin-film resistors (48 per channel) boasting 0.1% accuracy and an ultra-low drift of 30ppm. This gives the WARMER R2R its distinctly captivating sound signature.

Radiating with vibrancy

Extra-large two-channel

LED backlit true mechanical VU meters

The device uses a 46W low-noise, low-frequency toroidal audio linear transformer. Toroidal transformers have innate advantages: the toroidal core made with non-oriented silicon steel strips provides high efficiency and low eddy current loss, while the corner-free coils result in a more uniform magnetic field and less leakage. Thanks to this power supply, the WARMER R2R is fed clean power that allows it to produce pristine, immaculate sound.

Dedicated button

For a better experience

Like the K-series of desktop audio gear, it features a classic square and round design. This design seamlessly blends vintage charm with minimalist aesthetics, demonstrating careful consideration of both function and form. The grille pattern allows heat to be dissipated more quickly, ensuring the device stably provides high-quality audio for years to come.

Minimalist vintage look

Dependable heat dissipation

NOS (non-oversampling) mode: Decodes while preserving the original sample rate, providing the allure of pristine, original audio. Indulge in a pure, captivating musical experience.

OS (oversampling mode): Globally upsamples to a sampling rate of 384kHz, for better audio performance and a more detailed, clear sound.

Double the fun

NOS/OS modes

The independent Type-C port allows you to simultaneously charge and use via an adapter, ensuring you always have the power to enjoy lossless audio.

Widely compatible

Supports UAC1.0/2.0
