Would be great to see some pictures of your setup with WiiM product and exact audio configuration to give others some ideas and recommendations

.
My setup is modest but meets my needs. It consists of a WiiM Mini, with Aux In coming from a preamp which is connected to my JVC turntable (which I purchased in 1979), and Aux Out feeding into an 11-year-old Bose Wave Radio, which has pretty impressive sound for its size, thanks to acoustic research by Bose.
Rounding the whole setup out is a DLNA server running on a Raspberry Pi (which is a small system-on-chip computer originally sold for educational purposes), allowing me to play my entire CD library. So I have access to all my media in one form or another, largely consisting of 20th Century classical music (primarily American and British) and the French Impressionists (who straddle the turn of the 20th Century). And I also like A very few Broadway musicals (don't hate me!).
Plus free content from Amazon Music, where I have access to all manner of jazz from the 1930s through 1960s and beyond.
Then there's various radio stations to listen to as well, from TuneIn, vTuner and BBC Radio.
I had been trying for a couple years to get Rune Audio (also running on a Raspberry Pi) to work as a client for my DLNA server in the role which the WiiM Mini Is now functioning. But it was always crashing and then I had to rebuild the media library and it was a big pain.
Things are so different with the WiiM Mini, I have access to everything literally at my fingertips! The WiiM Mini absolutely NEVER crashes! There are some enhancements that I would like to see to the WiiM Home app, but I'm not complaining.
