Battery powered, high resolution capable DAC?


Is there such an animal? Could one be made with an existing DAC and a battery power solution like the Red Wine Audio Black Lightning?

So I guess the trick is knowing the voltage of the DAC? I know my PS Audio PWD uses multiple voltages and therefore is not a candidate. That said, I would prefer something designed to be used with battery power from the get go.

I'll check out the Ack DAC and I just found out that Red Wine Audio will have a hi res DAC in a couple months.
Checked the Ack and it is only 16 bit capable according to what I found on their product page - so that one is a non-starter.
