Maybe is a fault with yours ak380 , my AK240 is way better in Balanced than in SE , it has more power and more air in the sound, the soundstage is allready awsome in Se it has a very wide picture so unlike the 901 that in se the soundstage is "normal" and opens in Balanced, the ak240 in Se is allready more open than the 901 the stereo separation is first rate, i never eard a ak380 but is hard to believe that is a downgrade or is it..
I had the 240 but not anymore. I agree the balance out from 240 is better than se from my experience. With my 380 though se wins out. As i've been trying to a-b bal and se for the past couple of weeks. Se sounds fuller, clearer to me. Other have also spoken out in the 380 thread.
What i was agreeing to is bal isn't necessarily better especially with ak, in my case with the 380.
Add to that is my recent experience with the hm901s elfidelity balanced card vs minibox gold and/or musical amp card. Balance card sounded thin but separation and soundstage was a bit wider, but not by much. The other two card sounded fuller and really more to my liking.
Finally, and i have to admit it's not an apples to apples comparison, and not particularly dap related. He1000 with violectric v200, masskobo 404, liquid carbon. via 380 - crystal cable 3.5 to rca except for masskobo, this is via 2.5-2.5 bal whiplash silver 8 wire. The best was with the v200 (only in se) Next was lc bal, then masskobo 404 bal.
If it's just the lc, then se vs bal, bal wins out. Same thing with rxmk3-b, cdm and intruder, and hd650.
In general as i use the daps and mojo, more often than not, i've decided to give up on bal for the time being with these and iems. Hd650 has to be bal. he1k, i'm still on the fence but will decide soon.
Reading through what i wrote now, it would seem it would depend on the combo more. I'm excited to test out the combinations now. Maybe when i have more time...
