I also think the big elephant in the room that was also in the article I read is that Spotify will only be 16 bit, CD quality. So I don’t think they will be on par for the quality of sound regardless for hi-res unless you are using a chord up scaler.
I am all streaming right now, or Vinyl so Roon is pretty solid for me. I should have Matrix Audio Streamers/DACs that are Certified Roon Endpoints in every listening room by next week, besides my two-channel room where I am using a NAD streamer Certified Roon endpoint with Dirac.
It is kinda crazy to think how far I have gone to change my entire system in my house all based around ROON!!! Pretty much every DAC is now going up for sale or being traded out. So I agree I am not changing anything for Spotify, they are decent for when I work out or maybe driving in the truck but if the service or device doesn’t implement with Roon it is not for my personal ownership or subscription to the service at this point.
I am glad I listened to you and @ProfFalkin about the amazing strengths of Roon, it is a music lover streaming dream. I just wish honestly Qobuz would up its North America Catalog so I could dump Tidal. Hopefully in the future.
