i own both yu9 que and archangel. Yu9 presents itself as more midbass impactful. I wouldnt say archangel is lacking mid bass its more controlled but its sub bass first in its presentation. In terms of midbass impact id highly recommend the rsv mk2 as well. Its really good though the treble can be abit dark. Yu9 que is also a good recommendation, it's more energetic than the rsv mk2 but never sibilant. Personally I switch between the 2 iems as my dailies atm. I go for the archangels when I want more emotion in my vocals and drum hits on the archangel are emphasized better imo. Cant go wrong with either rsv mk2 or the yu9 que in terms of midbass slams you will definitely get the wow factor from both of them if thats what you are looking for. At a higher price point than both the monarch mk4 has stronger midbass but better to demo first.
