Get a stack. It looks good. And you can upgrade/replace.JDS Atom + JDS Dac or Schiit depending on which have the lower shipping cost.

You could also got the used route.

I don't really like Fiio it sounds too cheap to me, they had a lot of bad/average products before becoming OK, but that's just my impression.
I'd rather have a UK company (Schiit) or JDS (JDS Labs) product (that will have most part sourced from China, I know)
