A good streamer cashes the file, isolates electrically and vibration, and provides an enormously low noise floor in the output. I have owned many streamers… and choose them based on their sound quality not the technology employed. I fiddled with trying to get good sound quality out of PCs and MACs… fiddling with power supplies, battery… etc. then my first high quality streamer, just put them all to shame. Then, every increment up had a profound improvement.
I come from an IT background. I don’t want to fix the whole plumbing system to get great sound in my audio system. I prefer to plunk down a box and have audiophile level sound. This is what they do. I now run off a $69 wifi extender and my streamer sounds as good as my equivalently priced high end analog rig,
A few folks have shown they can futz with the switch, and do all sorts of complicated intermediary steps and get a similar result… I am skeptical, but acknowledge it is probably possible. I would rather listen to music than futz with extra boxes and the infrastructure.
