After listening to DBA02-MKII, I found it has a very good detail and good sound stage stage and separation. However I found the treble is a bit bright and sometimes fatigue my ear.
Another problem is the bass is too light and loose.
Is there any IEM has good detail, sound stagestage and separation like in DBA02-MKII but has tight and deep base with less fatigue treble?
You can try Dunu DN-1000.
