Compact sized non-oversampling High End D/A converter.
The output stage amplifies the current from the DAC chip by push-pull current mirror with direct analog output. This novel approach results in a very musical sound quality.
There are 4 variations for each interface, COAXIAL (S/PDIF), USB (PC), OPTICAL (TOSLINK) and I2S. In addition to the current-mode output, you can connect directly with the conventional voltage-mode amplifier with this single model thanks to unified electronics topology employed in s504u
