About the Product
FiiO WARMER R2R Desktop DAC & Tube Buffer
Bring tube character and vintage charm to your audio system. The FiiO WARMER R2R combines a fully differential 24-bit R2R DAC with four JJ Electronic E88CC vacuum tubes, designed to give music a rich, warm presentation.
R2R decoding meets vacuum tubes
A precision 192-resistor DAC works alongside the tube buffer stage. Select NOS mode to preserve the original sampling rate or OS mode for upsampling to 384kHz.
