I haven't recently no, I did some testing of the Roon/210/861v8 vs MC200/ID41/861v8 initially when I did the switch to Roon. I didn't find it a major gap, I thought they were equally good. And I made sure of it since then by tweaking the NAS and the network with vibration control, better network equipment and grounding, cables etc.

And yes, the 210 unpacks the MQA tracks and they sound great in Trifield laugh

Edit: I think I misunderstood your question. But also I have a multichannel setup and listen to Trifield via 210/861v8 and 7.1 via ATV4K/UHD722/861v8 mostly so putting the 210 directly to the DSP8000SE's is not in my book. Although I wouldn't say no to an MQA stream aware update to the 861v8!
