So I finally found for the DAC+Amp I was looking for! It meets all my conditions: has optical in, large stereo jack out. Even more, it also has an AMP!
After having searched the Forum for quite a bit, I haven't found enough data about this device. One member seems happy while another member (leeperry) seems to say that Fubar sucks.
But I haven't found any other optical-in & decent price DAC here in Sweden (since I don't want anything over 300 Euro).
