SQ Melco NA-1 v ultraRendu v Roon NUC

I'm searching for a new device to feed my QB-9. Anyone compared any of these?
Is the QB-9 upgraded to DSD?
I am in the same boat. Got the DSD upgrade but driving it with and old i3 pc. Am going to buy a ultraRenddu or a sms 200 Ultra Neo. Already ordered a RS-2 Upton for power. It will be a month before I can report.

Since you asked the question a year ago did you pull the trigger on anything?
Yes, I had my QB-9 upgraded to DSD version (super happy with that!).
I ended up getting an Intel NUC 7i3BNH and installed Roon. Roon is wonderful and I will not be going back.
