Look – this thread is probably largely interesting but not completely helpful to what you are trying to do. You will not be convinced one way or the other by people stating their opinions between "bits are bits and the rest of charlatans separating fools from their money" and the "every strand from PSU to ethernet plug to digital out makes a huge difference".
This hobby requires work. Do some listening. Decide for yourself if (a) you can hear a difference and (b) that difference is worth a delta in spend.
FWIW, I had a Node2, which I used for some time as a streamer to a Chord 2qute (via coax). Then I bought a used Auralic Aries (the original w/ dual femto and linear power supply – via USB). I even tried it with a wall wart power supply... and in my experience, I thought I could hear significant differences in all three configs, and in ascending order of preference:
Node 2 -> 2Qute
Aries w/ wall wart -> 2Qute
Aries w/ LPS -> 2Qute
Tangential but slightly related... I even got a fancier USB cable (from Curious USB) last summer, and I think it makes a difference. Which goes against everything I was taught to believe about data transfer, error correction, etc... and I'd like to think as someone who was figuring out SCSI terminations in the 80s, that I've spent some time around data transfer over cables.
I can't promise you'd find the same result, but I definitely felt there were very noticeable sound differences across the three streaming scenarios above. I can't explain it with sound theoretical reasons (but know others have, frequently related to noise introduced by lower quality power supplies) – and up until doing that work myself, was in the "bits are bits" camp. In fact, I worked for years a networking company, and am still friends with product managers who design enterprise grade switches... and yet I still heard what I heard.
So do the work of listening to different setups! Find gear that has money back guarantees and do some listening. You'll also learn a whole bunch of other things about what you like and don't like as a side benefit, and the more you listen across different combinations of gear, the more you form an opinion of what works for your own tastes (hint: it may not be what measures best or is the darling of one or another forum).
You may even realize that the journey of 'doing the work' is just as, if not more, enjoyable as arriving at some final destination of a finished system :)
