Very nice stereo dac, with it’s own volume control (no preamp needed), looks to have the last best 4 x AD (Analog Devices) R2R Ladder dac chips in it, just can’t make out the nos.

:Design: Two-channel DAC/Preamp with new 24/192 DAC chip
:D/A Conversion: 24-bit Ladder (8x Oversampling). 2 DACs per Channel (Differential Operation)
:Dynamic Range: 132 dB
