I'm sorry, I made a mistake typing on my keyboard. I meant "listening songs 10 metres closer". I tried ibasso dc03 pro, sonata tempotec E44 and Fiio Q1 mark 2. In my opinion: Depth 9 out of 10 Layering 9 out of 10

I'm not UA4 owner despite I just bought it. Anyway I own KA17 and I can tell you that soundstage is, I think, the strongest point of this DAC. It's immersive as anything else. To make things clearer is like you are listening songs 10m comparing to my other DACs. I hope I've been clear😅
