Looking forward to sell my M2Tech Young DAC. I've been using this DAC for one year. There is no visible scratches as the outer part is a slab of aluminum. The sound quality is excellent (http://www.stereophile.com/content/m2tech-young-da-processor-amp-palmer-power-station-battery-power-supply).
Shipping will include: original carton, USB cable, power adaptor. If you can pick up in Norrköping, Sweden then I can throw in a linear power supply (lab-bench) for free.
