Letting go of my trusty April Music Stello U3 since I no longer need it with my new DAC. It has been a great unit. Bought new from Moon Audio and I kept the original box. Uses the XMOS chip and is bus powered. It literally made my Burson DA-160 sound twice as good. Price is firm for the moment. Please contact me with any questions. I'll charge exact shipping for out the country. First come first serve.
