15k for streamer and dac....how much on each?

Try a used Sonore OpticalRendu for under $1500. This is a streamer and not a music server. I use a $500 DELL computer for my music server. That server is in my guest room under a bed. No monitor, keyboard, or mouse is used. The audio systems in my home are far away from this cheap music server (computer).

This will sound as good as what most will tell you to use a dedicated server/streamer next to your DAC. This is because you will use Fibre Optic in this setup. 

I also use ROON to make my life easier.

For that $15K, you are looking at a potential Playback Designs DAC. Infact, that is my goal, but I will use a PlayBack Designs streamer that I got for $2k. It is also ROON READY and is identical to the Sonore OpticalRendu in what it is trying to do (when using the fibre Plink connector).

I would still be using the DELL computer in the guest room with the PlayBack Desings DAC. PBD sells a new streamer and server combo for $13k that you can keep next to your DAC. My cheaper combo is more financially palatable.

Well it’s your money and is totally up to you how to split between streamer and dac.
Some will tell you that all streamers sound the same and there’s no point to get out of the $500-$1200 range, some will tell to use a computer, some will say you need a good streamer because they make a difference. 

Do your research and come up with a list of candidates then post to get some thoughts from real owners.

Very specific threads about digital are tough to keep on track. And yours is really vague. Good luck. 

I'd split 2/3 in favor of the DAC.  the DAC is the heart of your digital system.
