Unit was purchased originally as a 36S and factory upgraded to a 360S ($2500.00). It still has the original faceplate but i have all the necessary documentation and the certification on the bottom of the unit.
This DAC is mint and trouble-free. The sound quality is legendary even measured against today's digital components- superb bass and very analog-like (liquid and smooth). the DAC is HDCD compatible as well.
I also have a PS Audio Radian Right-Angle PC (available) which further improves the performance over the stock power cord.
