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!!!

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. 
DSD 512 is a larger file - more bits more processing ... higher sample rate ... requires more powerful processing.
Is the question really about ethernet through-put or is it about processing capacity?
@rego, it handled DSD256 or maybe 512 if connected over USB.  But only DSD64 over ethernet.  So processing capacity isn't the issue.  Maybe it doesn't have gigabit ethernet chip?
I would consider the Matrix Element-X. I have not heard it, but because of the good reviews, I’d try to get one on approval. It’s said to be neutral and bulletproof.

DACs of a certain price will almost certainly be Roon, Tidal, and Qobuz compatible. If you don't want to use those features, just ignore them.

@ssmaudio the only two "inputs" to the Lumin T2 are Ethernet or a USB drive. Over Ethernet, it receives the original audio data via UPnP (or Roon RAAT), so it will get the DSD512 audio file directly and play it. Same for a DSD512 file on a USB drive.

Since you're talking about using the analog outputs, there's no concern with "outputting" DSD512. But if you did hook up an external DAC, DSD512 will go out over USB but not BNC S/PDIF.
