There’s no denying Roon is an attractive UI and a decent organizer, possibly the best but if I am going to impose Roon’s DSP engine and RAAT pipeline on my X1, I might as well use a cheaper streaming system. It’s a compromise too far.
I trialled it, I liked a few things, but when compared to my native use of the X1 there was a noticeable detrimental effect. To a lesser degree Tidal does and to me Quobuz has the least detrimental effect of the non native applications I have used.
Having accepted they all have flaws. I chose to use Tidal connect for casual listening and music discovery. However, when I really sit down to stream & listen to full albums in a quiet environment, the most immersive and engaging way is Lumin direct. It’s just more revealing, less veiled, more vivid, yet it retains a refinement which I like.
IMHO these differences at least in Tidal and Quobuz are not night and day and I guess would be much less noticeable if the users system is not particularly revealing but I do believe they would still be easily detectable on most "decent" systems.
