As I have understood streaming over the many years that I have been doing it (remember the Griffin iMic?), the "streamed" files are downloaded, cached and replayed by the given software: Apple Music/iTunes, Spotify, Qobuz et al.
Although someone of you may refute that, it seems that the problem of line, processor, cable etc. noise has largely been solved by well-wrought(writ?) playback software.
Just measuring the sound floor in a quiet NJ den, I get readings of 27-30dB.
Whose ears and brain can process that amount of ambient hash and hear the "effect" of AC, cable, fiber transmission?
