Product details

The FiiO WARMER R2R is a highly advanced HiFi component that combines digital technology with an analog sound character. At the heart of the device is a fully balanced 24-bit R2R DAC, equipped with 192 high-precision thin-film resistors. These resistors operate with a tolerance of only 0.1 percent and minimal drift, resulting in a musical and natural sound profile. The playback is detailed, smooth, and organic, making it ideal for audiophile demands. The DAC is complemented by four selected JJ-Electronic E88CC tubes, which add warmth and fullness to the sound. The WARMER R2R supports PCM up to 384 kHz/32 bit as well as DSD256 via USB and offers high resolutions through coaxial and Toslink inputs. The RCA and XLR outputs can be used simultaneously, and the device can switch between NOS and OS to enable different sound profiles. Two LED VU meters visualize the music signal and emphasize the elegant retro aesthetic of the device. A powerful 46-watt toroidal power supply ensures stable power delivery and minimizes noise and interference.

  • Fully balanced 24-bit R2R DAC for natural sound
  • Four JJ-Electronic E88CC tubes for added warmth
  • Supports PCM up to 384 kHz/32 bit and DSD256
  • Switchable between NOS and OS for a flexible listening experience.
