I've been using this unit for about 5 months now. No dings or dents that I know of, it's literally been on the same spot in my room for months. Comes with box and papers, everything is in good shape. I haven't even used the USB cable.
Includes USPS Priority Mail to CONUS
Great amp, even better DAC.
Powers my Sennheiers, Grados, Audezes, and Hifiman cans with ease.
