There is a Yamamoto YDA-01 available used here now. These rarely come up for sale, and are excellent. You can read the 6moons review for details. An incredible DAC. Beauty to look at too...
And as an addendum to my Yamamoto recommendation, I would also suggest that you don't get too caught up in just the DAC chip used in a DAC (though these are important and will affect the sound). Do not forget the importance of a great power supply and a great analog output stage.
Are there even any reviews of the new Oppo out there? Only been out a week. And judging by the improvements offered by ModWright, the power supply and analog output stages can be improved to a considerable degree.
Not that it doesn't look awesome. But if the OP is looking just for a DAC, then I'd go with a dedicated DAC where money isn't spent on headphone outputs, video circuitry and a transport mechanism.
It would be helpful to know what you currently have and what sound characteristics are important to you and/or you would like to improve. Otherwise this is just shooting in the dark.
