I am afraid only you might answer that. As for anything hifi, the chain from source to can must match.
The thing about the Oppo, is that you can safely use whatever can you want, apart from something like a Stax, as they need dedicated amps. For the top end cans, it is a fairly good match.
It also needs some love, as in a great source, to sound its best.
Some people would disagree with everything I just wrote, as they do not hear any difference. To me that is crazy, if you love music: The differences are distinct and clear. Which brings us back to what you find yourself. Some people, like me, love the Oppo, others find it too poor sounding, while others find it a waste of money, as it sound like any other DAC.
My only advice, would be never to by anything without some form of return policy.
Going by your posting history, you appear to be into gaming. The Oppo has both USB and toslink inputs, but no gaming tech for it XMOS driver used for USB. If you want any gaming tech for sound on your PC, you will need to use another sound card for that, and feed it into the oppo. Personally, I think that is a waste, compared to a great PC sound card. The sound in games, is not that great to begin with.
The Oppo makes sense for uncompressed music at 16/44.1 and beyond.
