I bought this DAC/AMP recently off another head-fier. I literally plugged them in and used it for about 30 minutes before putting it back in the box to make sure everything is in good working order. I bought a bunch of other dacs/amps due to upgradetitis and have no need for this one. Excellent condition, comes with box and accessories such as usb cable and power cable. Free shipping ConUSA and Paypal fees included.
