To be honest, I suspect the new Oppo's playback from a USB stick is unlikely to be as good sounding as using a Mac Mini with Audirvana Plus or a PC with similar tweaks.
I do not use the DAC in my 93 but some people do and the async USB would be nice for them. Async usb could also be used for pass-thru of the digital signal to a DAC that does not not have aysnc USB - sort of a USB to S/PDIF converter - which is what I would like it for.
