Would anyone be interested in trading a Pico Slim for a Pico Amp/DAC? My Pico slim is black with serial number in the 100s. It has never been used without the leather case. I have all the accessories (note that the charger has a UK plug but I can supply a cheap adaptor) including the usb charging cable. I'm looking to trade for a Pico Amp/DAC of any color. PM if interested.
