This unit is like new. It was purchased, used for 2 weeks, then forwarded to an authorized service center to upgrade to a Gen 2 unit, which gives it an upgraded DAC, bringing it closer to Wandla quality processing. I have not used it since receipt other than to confirm its operation. Its incredibly compact size packs a powerful amplifier section (6 watts @ 50ohms), giving headphones plenty of head space to perform at their best. Price includes PP fees and UPS shipping. Please feel free to contact me with any questions. Thanks for looking!
