WARMER R2R 
Opt for a richer sound 
The ultimate setup for a warm sound 
The WARMER R2R is inspired by the legacy of the timeless Hong Kong band The Wynners. As the name suggests, the WARMER R2R DAC aims to give music an invitingly warm and beautiful tube sound. 
From the mesmerizing vibrations of the vintage VU meters in warm tones to the golden combination of R2R DAC and vacuum tubes, the WARMER R2R lets you feel the warmth of the music in every listening experience. 

This is an R2R DAC + tube preamplifier 
Extensive inputs and outputs 
Flexible connection with other systems 
USB/optical/coaxial inputs: Connect your smartphone, computer, digital music player, CD player, and more, and easily switch between inputs with a rotary knob. 
RCA and XLR line outputs: Connect speakers, amplifiers, DACs, and headphone amplifiers, with simultaneous output supported via both outputs. 

Uniquely fascinating 
Proprietary, fully differential, true 24-bit R2R resistor array DAC 
The star of the show is FIIO's proprietary fully differential 24-bit R2R DAC from FIIO, which is built with a total of 192 high-precision thin-film resistors (48 per channel) and has an accuracy of 0.1% and an extremely low drift of 30 ppm. This gives the WARMER R2R its distinctive, fascinating sound. 

Opt for a richer taste 
Four JJ Electronic E88CC tubes 
The tube buffer stage is powered by four brand new JJ Electronic E88CC tubes from Slovakia. The tubes are powered by a ±28V high-voltage power supply and feature a long life of 10,000 hours. The core circuitry of the classic tube buffer preamplifier has been optimized to achieve a sweet, organic tube sound that adds a delightful richness and fullness to your music. 
*Founded in 1993, JJ Electronic is a world-renowned manufacturer of vacuum tubes, electrolytic capacitors, and premium audio amplifiers. JJ tubes and capacitors are very popular in high-end audio and guitar amplifiers and are often used in guitar and audio amplifiers, recording studio equipment, and audio devices. 

Radiant vibrancy 
Extra-large dual-channel LED-backlit analog, true mechanical VU meters 
The true mechanical VU meter with retro backlighting in warm tones is powered by a dedicated IC. When the music plays, the meter moves harmoniously with it, immersing you in your own exclusive music party. Don't just hear music, see and feel it too. 

Pure, clear sound 
46 W low-noise, linear power supply with low ripple 
The device uses a 46 W linear transformer with low noise and low frequency. Toroidal transformers have inherent advantages: The toroidal transformer made of non-oriented silicon steel strips offers high efficiency and low eddy current losses, while the corner-free coils result in a more uniform magnetic field and less dispersion. Thanks to this power supply, the WARMER R2R is supplied with clean energy, enabling it to produce a flawless, unadulterated sound. 

Minimalist vintage look 
Reliable heat dissipation 
Like the K series of desktop audio devices, it features a classic square and round design. This design seamlessly combines vintage charm with minimalist aesthetics and demonstrates a careful consideration of function and form. The grille design allows for faster heat dissipation and ensures that the device delivers stable, high-quality audio for years to come. 

Twice the fun 
NOS/OS modes 
NOS mode (Non-Oversampling): Decodes while maintaining the original sampling rate and offers the appeal of pristine, original sound. Enjoy a pure, captivating music experience. 
OS mode (Oversampling): Global oversampling to a sampling rate of 384 kHz for better audio performance and a more detailed, clearer sound. 

Wide compatibility 
Supports UAC1.0/2.0 
Switch between UAC1.0/2.0 modes with a simple lever operation. Easy connection for plug-and-play use with devices such as computers, Switch, PS5, players, and smartphones. Say goodbye to limitations in your music world.
