With regards to sound - Yes!

As I listen to a lot of MQA material, I would not want it going anywhere near the 861 as that will strip the MQA encoding.
Even before I had MQA, the 861 could sound a little 'flat' and less engaging in comparison to the 818v3.

As I'm now using Analogue active monitors, the analogue output stage on the 818v3 seriously trumps the 861's OA18's.

I used to use the 818v3 connected via USB to my PC and streamed Spotify with good effect - moving to Roon/Tidal (with MQA) is another level...

Cheers,

Steve
