Warmer R2R | Desktop R2R Tube Buffer and DAC

Go for a bolder flavour | The ultimate warm-sounding setup
The WARMER R2R draws its inspiration from the legacy of the timeless Hong Kong brand, 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.

This is an R2R DAC + tube amplifier | Extensive inputs and outputs | Flexibly connect to other systems
USB/optical/coaxial inputs: Connect your phone, computer, digital music player, CD player, and more while easily switching between inputs with a knob.

RCA and XLR line outputs: Connect to speakers, amplifiers, DACs, and headphone amplifiers, with support for simultaneous output across both outputs.

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.

Go for a bolder flavour | Four JJ Electronic E88CC tubes
Powering the tube buffer stage are four brand-new JJ Electronic E88CC valves imported from Slovakia. The tubes are powered by a ±28V power supply and feature a long-lasting service life of 10000 hours. The core circuitry of the classic tube buffer preamplifier has been optimized to impart a sweet, organic tube flavour, giving your music a delightful richness and fullness.

Radiating with vibrancy | Extra-large two-channel LED backlit true mechanical VU meters
The retro warm-hued backlit true mechanical VU meter is powered by a dedicated IC. When the music sounds, the meter moves in harmony, immersing you in your own exclusive music party. Don’t just listen to music, also see and feel the music.

Dedicated button | For a better experience
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.

Minimalist vintage look | Dependable heat dissipation
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.

Double the fun | NOS/OS modes
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 upsample to a sampling rate of 384kHz, for better audio performance and a more detailed, clear sound.

Widely compatible | Supports UAC1.0/2.0
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.
