Not sure if installing roon is going to be of value for the sound quality unless you use some of the dsp included as part of Roon, which I don’t find very appealing. I think the overlay of this on top of qobuz maybe on the neutral side.
Streaming direct from tidal or qobuz is just as good or maybe even better. Also the lumin Interface is quite good as far as sound is concerned, although the Interface itself is horrifying to use and requires a bit of a learning curve, and roon is so much better and easier to deal with.
The lumin ap I'm not sure you knew this but was designed by monkeys. I just wish they would've spent more time and considered human involvement when using it because I think it has promise due to sound quality being a little bit better than roon.
