High end streamer/server profound choice

I have been very happy with Melco.  They don’t supply a DAC, and you don’t mention if you have one.  If not, that will take a major chunk of the budget 

You are free to waste your money as you choose. I know I pay too much for things some time to avoid hassle. You know what is best for you.

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.
