I agree with
mep re the Tidal & Roon combo
The crazy thing about Roon, if you read that late 2018 article (like 9 or 10 pages) about the dCS Rossini DAC and player, and then the Tidal and Roon Primer as the last 3 or 4 pages. in Absolute Sound I believe, they give a really detailed plug on why Roon is so good and how it actually has their own module that sits on the dCS Rossini Dac/player that enables u to use dCS rendering or Roon. The latest on that I just now saw in the Stereophile May 28 article this year about the "Roon Sound" itself, aside from being a database & zone management system n software. Worth reading.

Excerpt is interesting: >>>
Given that the Roon module is part of the Rossini v2.0 upgrade and cannot be evaluated separately, I first evaluated the Roon upgrade in a different context. I used Roon to play the beginning of my go-to track for dynamics, transparency, massed forces, huge and deep soundstage, pounding bass and tinkling triangles—Iván Fischer and the Budapest Festival Orchestra's performance of Mahler's Symphony 3 (DSD64/Channel Classics CCS SA 38817)—through Network Bridge/Vivaldi v2.11 before and immediately after performing the latest Network Bridge 406 firmware upgrade. This comparison revealed that the new module enables Roon to deliver fuller and more naturally color-saturated sound.

That said, most of the real world isn't listening to dCS & D'Agostino and Wilson Audio Alexia 2 systems, but, when using Roon and Tidal to play MQA over a $800 Powernode 2i by Bluesound, having Roon to build your listening exposure is amazing. The combo is really special.
The writeup of each artist, and all the connections to other artists is so incredible for exposing yourself to so many more artists thru using Roon. I never used the Aurender app here, once in a while the Bluesound app, but mostly Roon because it is so clearly organized in bring your external drives and gear into one nice music libary, and is forcing me to expand my artist library because of their artist writeups.
The Roon primer article is a good read
bluegrassphile , (the last part of the dCS article at Absolute Sound, made for normal budget audiphiles

, shows the Roon interface and what I was talking about how it gives you detailed artist info, and also gives you a rabbit trail to see who they have played and recorded with , see the article "A Roon Primer Blog"by Alan Taffel | Nov 19th, 2018
