Thanks @Axesd, the usb player I was referring too is here -> https://play.google.com/store/apps/details?id=com.extreamsd.usbaudioplayerpro&hl=en
It can output on most phones to an external dac at the full resolution of the dac with this software.
So up to 384 k for my Hugo.
The OPO is supposed to be able to output 192k natively to the dac (so its above 48k already) with any software, without the use of this usb software (which has its own audio driver).
