Better to listen to potential units and compare, and only sell your OPPO after finding a better replacement. Versus selling the OPPO only to not find anything you like and regretting that you can't get the OPPO back.
To answer your original question, there are DACs in your budget that some would definitely consider a better choice than the OPPO, but there are also people would would have the opposite opinion. Without knowing what you find lacking, I think any suggestions could accidentally send you down the wrong path.
