I don't really know if the digital out from the Oppo would resolve DSD. Certainly a computer would, no problem at all. Using software like JRiver or VLC, you will hear DSD reproduction.
You would have to read the specs of the digital out of the Oppo, and if that did not enlighten you, ask them
Maybe someone here can answer it. I know that my SONY universal player, that plays SACDs, will only output a 44.1, 16 bit signal from the digital out, but the Oppo is more advanced and newer
