Product Description
Extensive Inputs and Outputs, flexibly connect to other systems
This is an R2R DAC + tube amplifier! The WARMER R2R comes with three digital inputs of USB, optical and coaxial, two sets of line outputs of RCA and XLR, which contribute to flexible adaptation to your HiFi system.
Go for the bolder flavor, featuring four JJ Electronic E88CC Tubes
Powering the tube buffer stage of the WARMER R2R are four brand-new JJ Electronic E88CC valves 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 flavor, giving your music a delightful richness and fullness.
Uniquely Captivating, proprietary fully differential True 24Bit R2R Resistor Arrays DAC
The WARMER R2R introduces 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. It even doubles the fun by applying both the NOS (non-oversampling) mode and OS (oversampling mode) mode.
Radiating with Vibrancy, extra-large two-channel LED backlit Analog VU meters
The retro warm-hued backlit VU meter built in the WARMER R2R 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.
Pure Clean Sound, 46W Low-Noise Low-Ripple Linear Power Supply
THE WARMER R2R 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.
