Streamer with decent app

For a meaningful upgrade both sonically and with a good app at your budget, unless you’re extremely space constrained I think you’re much better off with a separate streamer and integrated amp/DAC.  The new Innuos Pulse Mini will give you a great streamer that comes with its excellent Sense app that’s praised for both its usability and sound quality.  And there’s a good used Bel Canto C5i integrated amp/DAC that’d make an excellent partner for the Innuos.  They both are small footprint products so won’t take up much more room than a one-box unit but will likely deliver much better performance and comes in well below your $3k price target.  Just one thought, and best of luck.

The Rose RS520 is a fun piece that should fit what you are looking for.  Could likely find a nice, lightly used one in your price range (they are $3695 new).

Keep in mind what devices you have. Some of the expensive streamers only work with Apple devices.

One reason I went with Roon, though they keep making updates I don’t want... <sigh>
