The FiiO R2R DAC features a headphone amplifier and uses FiiO’s 24+5-bit R2R PRO resistor array. Its segmented architecture decodes the 5 most significant bits using 31 thermometer-coded resistors, limiting the error accumulation found in traditional R2R designs and reducing distortion. The R2R sound signature is described as clear, smooth, natural, and warm.
