Excellent headphone amp with tons of power. Very clean, very quiet. Never an issue. I have 2 power supplies for it because, after I bought it, people on the Drop forum said the original version from Massdrop had the more powerful power supply and I ended up buying the WAU16-1000 power supply from Triad Magnetics all on its own ($22). The 02 amp was $99 new. I have the original boxes for the amp and the Triad power supply. Asking $75 + shipping (Power supplies are heavy!).

Great headphone amp! Lots of data out there on this for those liking measurements."....not everything that can be counted counts, and not everything that counts can be counted." William Bruce Cameron, Informal Sociology: A Casual Introduction to Sociological Thinking (1963)
