Yes, that should work, as I have a similar setup.
In my case I have the Roon "core" running on a high-end Dell, USB to a Mytek Brooklyn and PS Audio DirectStream DAC (two "zones" in Roon), controlled by my Android phone...and iPad. Works great!
I keep the volume set to "max" on Roon and vary it on the preamp.
