Streamer upgrade recommendations

A recent DAC upgrade from a Schiit Modi Multibit to the Mojo Mystique v3 is having me consider an upgrade to my digital source.

I currently use a W4S modded Sonos Connect, streaming Deezer HIFI (16bit FLAC).  I'm committed to Deezer and pretty invested in Sonos - with Connects in two systems and a few Sonos speakers.  I'm not keen on the idea of adding a dedicated music server/player.  (keep it simple.  Roon doesn't support Deezer fully anyways, I don't have stored music files)

With the constraints above considered, it seems my choices are limited.   Here's what I'm considering:

1. Bluesound Node 2i 
2. Simaudio Moon Mind2
3. Add SynchroMesh to Sonos Connect

I wonder if Node 2i would have better SQ than W4S Connect.

Moon Mind2 looks compelling - but zero reviews about it.

Would  Syncromesh SQ improvements be beyond a modded connect?

For options 1&2, I'd keep the Connect in the system for multi-room play as background music, parties, etc.

I know I should just demo all three, and will probably do so.  Was wondering if anyone has been in this situation or has recommendations.  Opinions welcome.   I wish the microrendu had deezer support...
