I like the WIIM Pro and Pro plus. I have the WIIM pro and works ok.
when all is ok, I suggest the Ever solo DMP-A6 Master edition and call it done.
my audiophile friend has one and i can say, it sounds very good
I have the A6 but using a Denafrips DAC for D/a conversion and that can add up $$$.
the Master Edition sounds great and always gets a software upgrade and new features always come into play.
but if budget being tight, get the WIIM Pro and you are ok for now
