The OP's DAC has AT&T, AES/EBU, SPDIF, and Toslink inputs. So he needs a streamer that has one or more of those types of outputs. It is worth noting the DAC chip is the PCM-63 multi-bit chip, one of the best chips ever made, and the DAC has 4 for balanced operation. Granted it won't do hi-rez (above 96 Hz) or DSD, but maybe he doesn't need that.
I admire the effort of the OP to try and find a one box solution. I am on a path to do the same but haven't succeeded. My DAC is the Lessloss 2004 MkII with PCM-1704 chips, a multi-bit chip as well and again one of the best chips made. This DAC has been in my system for 12 years. I haven't yet found a one box streamer/DAC unit to be able to meet my needs so I am still using an Auralic Aries LE to stream wirelessly from my NAS and then use the SPDIF output to my DAC. I also want nothing to do with USB and I don't share the warm and fuzzies that many seem to have for Roon, and I've tried it twice.
Overall from what I read of the OPs DAC it is quite good and a keeper. I'd focus on a streamer. The Auralic G1 is on my list to try since I have had good results with my existing Aroes LE. I have a few others I'd like to try as well. Tried the iFi Pro ISD and while I think it is a fine DAC, their Muzo app and wireless capability need some work.
