From what I can tell neither of those are made in China. I'll buy the best one for the best price like anyone. But I would like to support good audio gear made elsewhere too.
The Schiit is made in USA and Pro-ject, an Austrian based company, AFAIK manufactures in both the Czech Republic and Slovakia. Both have a 2-year warranty.
Both have an external power supply (not running off USB power) which also allows swapping out the switching power supply for a linear supply if desired.
The Schiit does not upsample whereas the Project upsamples to 352.8kHz or 384kHz, depending on the source sample rate. There are proponents for both unaltered native processing and upsampling; the theory behind upsampling being that digital aliasing filters can be applied at higher frequencies with less negative effect on the audio band (and the Pro-ject does have a two-position selectable filter).
I also do like the source sample rate indicators on the Pro-ject.
I think either would be a good choice, unfortunately it would probably be difficult to find a comparison between these two, unless you have the option of buying both with a no-hassle return of the "loser".
