building a system around Devialet Expert 200

Got a Devialet Expert 200 to go with a pair of VR5 Annv 2 speakers and while I can always feed it with my analog rig, Im wondering how to implement the digital side.  Have an old Olive 04HD with a bunch of music on it as well as an outboard drive with a bunch more.  How can I integrate these two sources? does anyone have experience backing up the Olive in a separate drive that I can read or use with a streamer?

TIA
