I have been enjoying Roon and Qobuz, running on a Roon Nucleus Plus server, connected to a PS Audio DirectStream DAC with a USB cable for several years now and find the sound quality to be awesome! I used to also have a Tidal subscription, but didn't need both of them, and had no complaints about the sound quality of that, though doing significant "A/B" testing, for some reason I can't explain, the sound quality of Qobuz seemed a tad bit better.
Before purchasing the Roon Nucleus Plus server, I ran Roon, Qobuz and Tidal on a Dell laptop, USB to the DAC and the sound quality of the USB on the Dell wasn't at all in the same league as the Roon server.
