A separate streamer and a DAC would be the way to go.
IFI or Bluesound streamer. $500 +. I have updated power supply on Bluesound and it is a good improvement.
Denafrips, Schiit or Topping would be some DAC around $1K or less. I have a $50 COAX from streamer to DAC. There is lots of debate about whether USB is better
There are many options of course. Some streamers have cumbersome interface to look for and play music
An inline filter is also an option such as a Network Acoustic ENO.
