Jwil, I have gone pure analogue in the past two years but up till then I ran digital files via Mac , iPod, iPad etc... Into several DAC's. You'll want to explore DAC's that have a USB. My favorite which to my ears in my modest system was MHDT paradisea - I also had a very inexpensive Lite DAC-Ah (about $130) that was awesome - not as smooth or dimensional as the MHDT but deep bass and dynamics galore. These did not have USB but I ran them with a USB adapter from Mapleshade. I believe the current model MHDT Havana has a USB input. Also the Mapleshade digital interconnect was paramount in delivering warm detailed and grain free sound - I suspect their USB cable would do the same.
So look for a great DAC and USB cable. - simple, I should have said that first!
Cheers
