Best way to output hi res files to DAC?


I'm looking for a media player I can upload hi res files to that will output digitally (digital coax ideally) to my Wadia amp.

The Wadia Intution has it's own up converting DAC so all it needs to receive is the raw digital output. Could be a hand held unit, whatever. The units I've seen including the Sony, Fiio etc only have analog out which doesn't help.

Since SQ isn't critical given the raw digital output, what would be the best most cost effective way to go? Or at least some options?

Sorry to tell you this, but it turns out that SQ =is= an issue even with raw digital output.
If you can do TOSLINK optical Amazon Fire TV box (<$100) running PLEX app ($5) with a cable like this http://www.amazon.com/XO-Resolution-Professional-Digital-Optical/dp/B003BM23FY to DAC should work quite well.

You would have to run free PLEX media server as well.

I am running a setup like this currently with excellent results in my 2 channel A/V system, but have not tried beyond CD resolution. I think it would work and not cost much to try though.
So no media servers capable of DSD with a digital out? That's surprising given the popularity of DAC's these days.
