This relatively economic box does MQA Project S2 you could connect it via USB either directly to the core device or to a USBridge like a Sonore Microrendu or Allo USbridge .

I use both of these in two setups, you can of course get better DACs are available of course but at a cost.

Another alternative would be Bluenote, I have no experience with their products but maybe Chrislayer can add his experience.

Lastly I do not have an MQA DAC and do not miss having it, Roon gives you the first unfold it is just the final render you are missing, I would focus on getting the sound you like.

YMMV
