I find in the "streamer" discussion, the access management and the DAC question is muddled. For sound quality, the DAC is the chief factor. If you plan on keep using your Chord as the DAC, then the streamer is solely for access convenience. Maybe a given streamer has a better built-in DAC than a Chord, but then you could get the same result by using a similar quality stand-alone DAC, which you could also use for the DAC step in CD playing. I think there recently was a thread of DAC-free streamers.
One thing I am not clear in your set-up: What is your current software interface? Website, Spotify app, Audirvana/Roon? Some people claim to hear differences with software interfaces. With trial versions available for free, that is an easy way to check one factor out. I compared Audirvana and Roon and could not detect anything. I use a Mac mini with SSD going to a Holoaudio May L2 DAC but only for local FLAC files. I don't stream.
