Streaming DSD to DAC options on home network

I know this topic is covered in various ways in different threads I have searched, but many of the solutions are possibly more than I need I think.
Present setup for discussion here is a Windows PC hard drive with 2 TB of DSD, high rez flac, and mp3’s that sends audio files via JRiver to either an OPPO 105 with built in ethernet/wifi, or a OPPO Sonica DAC which also has built in etherent/Wifi connection. Not worried about the non DSD files as they can be sent to the OPPO 105 and then any DAC via Coax.
Cannot use the OPPO 105 ethernet path to send DSD files to an external DAC though via Coax.

The preamp and amps, speakers are all in my system profile, but pretty decent transparent resolving gear.

If I were to want to try a different dedicated DAC that did not have etherent/wifi built in- what are the best options?

Prefer to use Ethernet cable and not wifi as people seem to think that is better here.
I don’t need a music server/HD. Really like JRiver.I do not use any streaming services right now except Spotify.
Might in the future, but right now play music via my PC hard drive over the network, or on my OPPO 105 as a CD/SACD transport.

I think I am looking simply for an ethernet bridge of some type to get music to the DAC correct?Something like an Auralic Aries or Aries Mini??
Final question- are these dedicated bridge units better than what is built into the OPPO 105 or OPPO
Sonica Dac??
Thanks for your input.
