In my system the WiiM Pro was the only streamer that was notably less good than other budget options (iFi Zen Stream, Raspberry Pi/Denafrips Iris, Denafrips ARCE). Streaming Roon, the Eversolo A8 was the best. Generally the differences were small but I would ditch the WiiM Pro.
Importance of streamer in audio chain
I have a wiim pro with a Deshelli dac 4399 chip and sparks op amps. Would I notice a difference by upgrading my streamer? My other equipment is a Rogue cm2 and Falcon Q7 speakers.
