Best streamers WITHOUT a DAC

Thanks, will look at that. Price range kind of open, would need to look at some alternatives.  As for features...

- decent OS with Android phone and Windows control

- support for Tidal, Qobuz, other  hi-rez streaming services, presumably similar to BlueOS, Sonos etc.  MQA too (why not?)

- Ethernet/wired network

- Support for Plex, Roon, JRiver or other network streaming apps &/or its own native network streaming app (I've got a 1Tb library)

Both BlueSound and Sonos do all that stuff and presumably other, mixers streamers do as well.  Don't need anything more exotic than that featurewise.  Fwiw I've had a hard time even finding comparisons of streamer comparisons where the digital output is feed through a reference DAC. 

Oh yeah, forgot!  Needs to be something with S/PDIF or AES/EBU digital outputs.  No USB.  Thanks!

You haven’t specified a budget but the Antipodes K50 would meet all your needs and deliver reference level performance.  It is $15k but one of the great servers in the world.  
 

A hybrid, 2 Box approach could be interesting.  Something like an Antipodes S40 with a Bricasti M5 would be half the price and is a pretty incredible solution.  $7400 combined and again, would do everything you are asking for.  
 

the Lumin U1 is a little older at this point but still offers great support for current platforms.  It is a streamer only at $6k

the U1 Mini is a smaller, more streamlined version at $2100.  All of these are a step up from a Node.

I am an Antipodes and Bricasti dealer.  I am considering Lumin at this time but am not a retailer at this time. 
 

I can highly recommend the iFi Zen Stream. Has S/PDIF out.

Aurender N-100C has a S/PIDF connection,  I use the USB version and enjoy it. Good luck with search.
