It is so what dependent on if you like fiddling with IT stuff or would rather not. If not… the better the streamer you own the better the sound will be. A good streamer isolates, noise wise, from your network connection and buffers the file… making the network connection relatively unimportant. My streamers work even when I can’t update a web page on my iPad. I recommend Aurender streamers.
Alternatively, you can fiddle with your routers, connections, regenerators, linear power supplies… etc… basically cleaning up the incoming pipelines. If you like IT and tweaking this is great fun and can bring the same benefits of getting a good streamer.
I was in IT for most of my career. I don’t want to screw around with the network. My vinyl leg sounds the same as my streaming leg and with high Rez files better than my CDs. My streamer works from a wall wart wifi extender and an Ethernet extender did not improve the sound… I have a high quality streamer.
So, either route can improve the sound greatly.
