I have the Wiim Ultra setup and working fine except for 1 issue, when I connect my turntable to the phono input and connect the earth I get a significant amount of hum/crackling through my speakers. I have tried swapping the turntable and the audio cable without any effect and when I connect a turntable direct into my amp, bypassing the Wiim Ultra, there is no issue. Just tried using the phono inputs on my Wiim Ultra and the earth on the seperate amp and and it works fine, I can only conclude the issue is with the earthing on my Wiim Ultra, what do we think?
