Here’s my opinion.
Using your current system and how my system evolved I would suggest a DAC.
My current sources are a Turntable, tape deck, DAC with Streamer (Moon 280D) into a McIntosh C2600 tube preamp and MC 302 amp and Sonus Faber Sonetto speakers. I used to think the speakers were the most important and based on upgrading from a NAD C375 with Sonus Faber Venere 3.0 with the Turntable and tape deck using the Node 2i as a DAC/Streamer. I will admit I believe the source is the most important.
I then upgraded my DAC and speakers - using a Moon 280D with built in Mind2. While I know Roon has great functionality I am find using in Moon 280D having it connected to my personal server for my digital music as well as linked into my TIDAL account.
Additionally your DAC can support your CD transport.
