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!!!

Question. I noticed some of the suggestions are due network streamers (like the Lumin T2 and X1). If I already have Roon, is there any reason to get a network streamer?  Thanks 
@ssmaudio Roon doesn't actually deliver audio to your DAC, unless the Roon Core (your Mac) is connected to your DAC via a USB audio connection.

In all other cases you still need a Roon "receiver" for the Roon Core to send the music data to, and that receiver then either renders it as analog audio if it is a DAC, or the receiver outputs it as digital audio to your DAC.

So when you wrote "I’ll connect to the streamer through a Roon core running on my Mac" I think we all assumed that meant connecting to a Roon Ready receiver that is on the same network as your Mac.
@nekoaudio , thanks for the explanation. Currently I use my Roon core on my Mac to connect wirelessly to an Exasound Sigma streamer that connects to the e38 DAC through usb. 
So is there any advantage to a network streamer?  Since Roon  already connecting wirelessly to the Sigma streamer.
