Need a headphones amp/dac solution that I can stream to from my NAS


Title kina says it all. I am looking for a piece of gear that is:

A) headphone amp
B) DAC
C) can stream to from Network NAS without using any of my other components so ethernet connection
D) Will work with JRiver (my current s/w)

E) Volume remote would be nice, but not a deal killer
F) Can work with a wide range of headphone impedances

G) Good sounding, does not have to be the best as I am just getting into the headphone aspect after years of being away

 
It will need to be something that will be recognized by the software as another zone that can be streamed to.

I have found bits and pieces but as yet nothing as a single component, although I am not against multiple pieces if they have everything listed above.

HELP please you Oracles of Audio....

I have an Antelope Platinum DAC connected to my PC via USB. The JRiver acts as the server to retrieve music from the ethernet NAS to the PC and out to the headphones connected to the DAC. I would be sure most similar DACs would be the same eg Chord, Ayre etc. It is the PC that does the music handling, not the DAC.
Use the PC to create the network drive to the NAS, point JRiver to the music file folder on the NAS drive and use the USB port to drive the DAC from the PC. easy peasy.
I think the Naim Uniti Atom and Nova may check all the boxes. The Nova does so for me, but I use Roon.
While I appreciate the suggestions and I have looked up several of the suggested units they mostly fail to address the network as I would prefer to run data over the 1gig network rather than a usb or some variation. My current set up uses a PS Directstream connected to the network but since I am using the balanced outputs I suppose I could use the singlended output from the Directstream to the headphone amp. I would have prefered a solution that did not require me to power up any of the other components but was looking for a amp/dac that could tie into network. The files stored on NAS are uncompressed flac files, so there is a lot of data to move.
