High end streamer/server profound choice

You will not be sorry. For the longest time I felt that it just couldn’t be that important... oh how wrong I was. I recommend Aurender. I have the W20SE, but the N10 is wonderful. They will have a model that perfectly fits your needs. Aurender seems to have figured out how to silence the whole unit and quiet it down as well as get the maximum natural sound out. I also have a N100. I used to have an Aurlic Aries G2...

Lucas Audio Lab can custom build a roon server/streamer to your system and budget.  He’ll also support you in optimizing it with updates in perpetuity. I have a lower end one ($3800) and will not be upgrading it again anytime soon.  Very honest, competent guy.  No bullshit.

Dac remains separate, horrifying to embed a dac inside a network player. 
Problem i have is being jerked around with all the separate pieces, and then replacing and adjusting and in the end never quite achieving your goal and ending up spending more with lots of equipment stting idle in boxes as its not worth it to sell.

so buy a quality reference piece that will achieve an exceptional result and wont look like a hodgepodge of boxes scattered all over.  I think we can combine the various pieces relating to players and servers.  Harder to do with amps, processors, dacs and stereo preamps, which should all be separate.  Integrated only makes sense if u live in manhattan. 

@jumia - I also came to the same conclusion to simplify rather than have all those boxes and cables.  However, I'll still get an audiophile ethernet switch for the sonic uptick.  

You can spend big money on a lovely streaming/server box with great user experience and great sound potential, but unless you invest significantly in optimising and cleaning the Ethernet feed to it, you won’t hear its full sonic potential.
