Hi all, new set up with WiiM amp and wharfdale 9.1 speakers. Connected up and play music and I’m getting some odd results. Listening to songs if there is a lot is Bass, singer with deep voice sounds good, sound of silence by disturbed sounds ok, anything that isn’t that deep I can barely hear the vocals. Playing. Pod cast people talking sounds like R2D2, but when a music jingle kicks in they sound ok. Anyone got any ideas? I’m new to all this!
