Purchased through Amazon.com about 3 months ago. Used it only inside the house and only for about 20 hours total. I just keep it inside the original box without opening it these days. Works perfectly and is in mint condition. Enjoyed it, but I prefer keeping the Micro BL instead. Definitely the best portable Bluetooth DAC/Amp that I've tried, and although it is not as detail-oriented as the Micro, the xDSD is definitely a bit smoother and subjectively more lyrical. Selling to CONUS only. Asking for $330 which includes Shipping Fees and Paypal Fees.
