An exceptional top-of-the-line balanced DAC. Top tier dynamics and excellent resolution. Has been my reference DAC for the past 4 years. Often used in pro applications but has been adopted by audiophiles due to its sound. This unit is in mint condition with no blemishes. I installed Hudson Hi-Fi rubber feet which can easily be removed (so it can stand in your desk and the bottom surface does not rub). It includes the original box.
