What Device To Perform The Upsampling?

Hello,

I’m using Audirvana 3.5 on my Mac-mini connected to a Denafrips Ares II DAC via USB. The Ares can be set to OS or NOS.

I kind of understand that upsampling and oversampling are different but similar but from a sound quality perspective, what has been your experience? Should Audirvana do all the upsampling and filtering and set the DAC to NOS, or the other way around?

Of course I could test this for myself but unfortunately I can’t get to my system for a while so I am curious about your own experiences.
