Bricasti Design M1 SE - W/ LAN Network Streamer - Version 1.51 V. Denafrips Terminator

I am stumbling along trying to put together a digital streaming system. Have a tidal account and stream through a Farad Power Supply, Roon Nucleus and a AudioQuest Dragon Fly Red,  into a Pass Labs XP 30 Line Stage Preamp, Pass Labs Class A mono blocs, Klipsch LaScala. Considering Bricasti Design M1 SE - Includes LAN Network Streamer - Latest Clock Upgrade Version 1.51 or Denafrips Terminator R2R DAC. My budget is under $10K and I like to buy used. Would appreciate the Forum's assistance in evaluating these components, how they would would work with the Roon Nucleus and what other components would be necessary or desired. I don't expect to use the Dragon Fly. It was used as a cheap way to get started.  My system is currently fully balanced.
