I don't use DSP or other shenanigans either, preferring 'native, as it were. Roon is fine on Innuos (been thrre, done that!). Roon is very good at showing all versions of a particular album, often at different res. Often difficult to compare if different masters. Hiwever, where I have a ripped original I can then compare against a known reference. I have Tidal and Qobuz, so there can be up to 8 or so different versions. Music discovery is also optimised having the two services, but I admit it;s a bit of an indulgence. On tbe sq front, Qobuz is well ahead, ime.
On the discover front, I do like the many links in the write up provided with most albums and seeing what Roon has to suggest on a similar front.
It's interesting to set up a playlist of some of your favourites and turn Roon Radio on and see what comes up. Of course, you then hear something you like, click on the various links and off you go! As you build your library, Roon learns more about you and the recommendations become more apposite, yet not so tight as to limit discovery.
The search and filter capability is awesome, so once you start expanding your library it doesn't become overwhelming.
