FiiO K11 R2R DAC and Headphone Amplifier for Home Audio or PC
DSD256 requires setting the DSD output mode to Native on the source device, internally converting to PCM before being decoded by the R2R resistor arrays. FIIO's newly self-developed four-channel fully differential 24bit R2R DAC consists of 2x 48 precision thin-film resistor arrays per channel, totaling 192 resistors with 0.1% tolerance and low temperature drift (30pm).
