I have to connect my iem's ONLY on 3.5 mm phone output or it's ok from my dac/amp? I use fiio btr5, Q3 and Sonata hd pro with UAPP. I Don't have any gear at me right nowby the way, the autoeq feature often won't show unless you have a music app playing. if you are playing music and it still doesn't show, then select "legacy mode". You can refer to my screenshot above.
