Bubba is correct. The ART DI/O takes an AC input.
The DAC you have linked to takes DC.
Quite a bit of the mods I do to the DI/O involve cleaning up the AC to DC section.
I would suggest you take a listen to a smART DI/O before you invest in that DAC.
You can build a power supply with any kind of transformer. As long as you are willing to throw money at it
