For what it is worth , I am currently using a Roon Nucleus with Bricasti M5 as Roon endpoint in my main rig, and can very much vouch for it. Real happy with the M5 since acquiring it back in March of this year. Considerable jump up in sound quality vs using Roon Nucleus as a server/streamer. Best streamer solution I have used in my room. Other solutions have included Bluesound Node N100 (the original cube), Node 2i, and Melco N1A. Current DAC (since 2019) has been Chord Qutest. Prior to that DAC was Bryston BDA1.
For those that have separate Streamers & DACS
What are some of your favorite streamers/servers strictly from a sound quality perspective? Please assume a stand-alone DAC. I've read such a variety of opinions on streamers and was interested in opinions from those that have tried different streamers on with their DACs.
