I agree with the suggestion for checking out the linemann bridge and the primare mp5 mk2. They are within your price range. WiiM Pro is a great option as well - best streaming software hands down!!
Another one that hasn't been mentioned is the Keces eBravo +/- P6 power upgrade. Approx $600/1000 respectively. This has the added advantage of integration with the linkplay system that WiiM uses...
