This is a fantastic DSD DAC/Pre/Headphone Amp. It has High Rez PCM and DSD decoding capabilities via USB, toslink, SPIDF and has an analog input. Also features the ability to drive your amplifiers directly acting as your systems preamp which I have done, it sounds great with plenty of drive for most any amplifier. I have compared this to a PS Audio DSD Dac and to be honest I don't hear any differences. I have the box, manual, remote (which still has protective plastic film) and power cord. This little unit retails for $2195.00, I'm asking only $1600.00 with free shipping to lower 48.
