I am also in the camp that MQA isn’t worth stressing over. If you buy the Node then you do have to use its DAC for MQA. The DAC in the Node isn’t unlistenable, but it’s a rare person in these forums that prefers it to their external DACs. Fwiw, the Node DAC has recently been upgraded, and I haven’t heard it, though I have only seen 1 user in Agon say it was a significant upgrade.
Roon is a software application that organizes all of your music files, both on hard drives and streaming services, and also attempts to improve Sound Quality. The previous sentence is as pithy as I can get describing it. In some respects it resembles Audirvana Plus, which you seem to have had an unhappy experience with. I suggest that you Google or You Tube Roon as there is a lot more to it, and Roon users here may have much more to add. Roon is a large and complicated program that doesn’t always run well on computers and streamers, so Roon started manufacturing hardware, essentially dedicated streamers customized to run their software
