SOLD ---
This is a direct digital amplifier in great condition. So it's basically a power DAC with USB input. 2x80w into 8 ohm. 2x40w into 4 ohm. Very transparent sounding. Original price 109 + shipping. I'm selling it for $60 shipped in Continental US. Note the unit does not come with a power supply. I can throw in a 19v 65w laptop power supply for free if needed.
