DAC + NAS streamer combo (NOT Tidal/Qobuz etc)


Hi, I’m looking for a stereo DAC and streamer that can stream from my local NAS server. I DON’T care about Tidal/Qobuz and all that crap: just my own music. An example is an Exasound e32/Sigma Streamer combo (I have their e38 + Sigma and it works beautifully).  I’ll connect to the streamer through a Roon core running on my Mac. Budget 3-4K. Used ok. Recommendations please?  
Most important to me is that the DAC be as neutral as possible (and of course work with Roon). All the ones I looked at that are Roon-reconnected on their website are for hi-res  streaming and seem to have a lot of bells and whistles with touch screens and other junk.  I want a basic but high quality DAC. 

Am connecting it to a Pass Labs xp32 preamp, First Watt j2 amp and Tannoy speakers.  Listen exclusively to classical and jazz. 
Thanks!!!

If you are not committed to blowing the $$ and don't mind a lil work I'd look at an Allo Signature, USB or DigiOne if you require SPDIF.. Get the Shanti (a killer 5 vDC LPS). 
2 USB A ports, I have an SSD in each. Native DSD decoding, Multiple pathways for Roon.
~$500 why spend more besides looks?
I'd recommend looking into the Lumin T2. MSRP is $4500 but a used or maybe demo unit is definitely inside your budget. I also think you will appreciate its excellent sound quality given the critical demands of classical and jazz.

It will stream music from your local NAS, works with Roon as well as other UPnP control software, and supports for DSD via its ESS DAC chips.
Qutest DAC - $1800 new ... DSD / PCM - 44.1 / 768 - 16 /32.
FPGA Type ... IMO does more of what a DAC does (should do).

Nuc Streamer - $700 +/- ... Darko Audio Review (choice of OS).
Low Power / High Performance for Dedicated Audio duty.
TDP 28W / 16 GB RAM / 1 TB NVMe / Quad Core
Plenty of power if your NAS won’t meet spec.

@jmarshak you are correct but those are most likely older units that don't have the Ethernet port. Yes can send back to update but just the Ethernet update is something like 1k. Again it would meet the OP requirements but starts to get expensive. Still something to consider.
The lumin sounds interesting. It supports DSD etc like I want. But I wonder whether it can do DSD 512 over ethernet from a NAS. The Bricasti said it could do DSD64 max.  Don’t understand why.
