See, that's what I am curious about. I am curious if there will even be an auditory difference between an external 24/192 DAC vs onboard audio which can technically output the same, but sounds noticeably worse than the surround sound I use now, before putting more money into better DACs.
No way to know unless we have the same usb device that you used.
And even then if the difference isn't drastic we can't answer for whether you can hear the difference.
