I am selling my Fiio E12 DIY. It optically in almost new condition. I only used it maybe for 20 hours. The only drawback is the little pin is stuck (that you can see on the photo). It works normally.
I tried to solder LME49990 on one of the empty sockets, but it did not work out... you could desolder it.
I am asking 150€ Shipping and Paypal fees included.
Check out the photos.
