Up for sale today is my Beyerdynamic A20 amp. It's a great little amp, well suited for high impedance headphones and all but the most demanding low impedance headphones. It never really got much use from me, as it came in a bundle with my DT1770's. Selling today because it's really only a novelty to me, and it's basically just collecting dust at this point. Comes in original box, with original booklets and stuff inside, as well as standard US power adapter and EU power adapter.
I'll cover shipping, shipped via USPS. CONUS only.
