Hello all, I'm parting my with Massdrop Objective2 headphone amp. It's in perfect condition and includes power supply. This is the desktop version, so inputs are RCA and are on the back of the unit rather than the 3.5mm front mounted input on the portable unit. It's in perfect condition and I'll ship to the lower 48 states for the asking price. Let me know! The Matrix CUBE in the photos below is already sold.
