FiiO Warmer R2R DAC combining true R2R architecture and tube buffer for a warm, engaging sound and broad connectivity. Read more.
The FiiO Warmer R2R is designed for listeners who want more than a purely technical presentation from their digital sources. Within the range of FiiO, this DAC stands out by combining a true R2R architecture with a carefully tuned tube buffer stage. Inspired by the timeless musical spirit associated with The Wynners, the focus is on warmth, flow and emotional engagement rather than clinical precision alone. It is well suited to long listening sessions across a wide variety of music styles.
At its core, the Warmer R2R features a fully differential 24-bit R2R DAC using a four-way architecture and 192 high-precision thin-film resistors. This design contributes to a stable, natural sound with convincing depth and texture. Users can choose between a NOS mode for a more relaxed, organic presentation or an oversampling mode for added precision. A comprehensive set of digital inputs, including USB, optical and coaxial, alongside RCA and XLR outputs, ensures easy compatibility with both modern and classic hi-fi components.
In practical systems, the Warmer R2R adds body and richness without masking detail. The tube buffer stage, powered by four JJ Electronic E88CC tubes, introduces a subtle harmonic sweetness while maintaining clarity. Supported by a robust linear power supply with a toroidal transformer, the DAC delivers a clean and stable signal. Whether paired with an integrated amplifier or a separate power amp, it encourages rediscovery of familiar recordings and offers a more immersive musical experience.
