Use your Hippo... I mean Oppo as a transport. Get the DAC listed below which has various D-to-A rates. Connect using toslink to help isolate the ground of the Oppo from the DAC (and, potentially, the rest of the system).

This DAC sounds particularly nice and compares well against very expensive DACs. It is an absolute steal. And If you don’t like it, the cost is so low that won’t matter.
This is a SIGNIFICANT step up in performance over the Oppo.
