Resolution, transparency not the most difficult aspect of sound quality to achieve with streaming. Yes, noise, both external and self generated can enter at many points, but even with less than best streamers relatively high resolution, transparency can be achieved assuming one has decent dac.
My experience has found timing greatly impacts digital sound quality. Get the timing right throughout entire streaming setup and the closer one gets to positive traits of analog. Correct timing allows largest soundstage, most stable imaging, and most importantly, greater sense of ease, relaxed musical experience. Jitter is what gives digital it's bad name, and the reason some maintain vinyl superior to digital. New custom build streamer I recently purchased was built with parts and components specifically chosen for lowest latency, low latency means less jitter. Using the same dac as with prior streamers, greater levels of resolution/transparency has certainly been achieved, but sense of ease or analog like sound qualities has been revelatory.
I observe ever decreasing levels of measured jitter in digital components, certainly large measure of why digital continues to improve.
Another critical thing to remember, you can never get back what has been lost earlier in streaming chain. No dac can clean up noise or jitter created earlier in chain, just as optical with it's total galvanic isolation can't restore whats been lost in regard to noise, the jitter manufactured within streamer has already contaminated the bit chain, even the finest asynchronous clocks in dacs can't restore whats been lost prior.
There is a reason why the best streamers attain higher levels of sound quality, lower latency/jitter and self generated noise. If dacs could really restore whats been lost streamers would all sound the same.
Finally, I presume digital at some point in future will finally surpass the very best analog/vinyl. Audiophile and/or digital engineers are paying close attention to these latency issues within digital components, Ever decreasing jitter will be achieved in future components, this along with ever decreasing noise will further improve digital sound quality.
