Great system. You are short on one aspect. A high quality streamer. It should be at the same level as your DAC, Preamp or amp. Given your system I would recommend an Aurender N200 or Aurender N250. These would provide the level of performance commiserate with the rest of your system.
I spent several years refusing to invest in a good streamer because it was basically the same thing as my MacBook or PC. That was one of the biggest mistakes I have ever made in audio. I completely wasted the time with grossly inferior sound quality. The sound quality of your CDs should equal the sound quality of stored files and streaming. However, Qobuz should sound better with their one half million high resolution albums.
A good streamer must be built with the same dedication to detail, and quality that any other audio component has to be. It needs an outstanding power supply, internally and externally shielding from noise, vibration... etc. This requires lots of design time, high quality parts and expertise. Aurender makes some of the best streamers... it is all they do. After owning a dozen other streamers over twenty years, I own two Aurender. My vinyl playback, CD, stored files and streaming all sound the same, the best sound I have every had. You can see my virtual systems under my user ID.
