I'm sorry, I meant among balanced armature earphones. I've not had enough time to get the full gist of the SE846, but I can definitively say that in terms of taut/full bass, this earphone is simply in its own space. Again, I heard only the balanced tips so cannot comment on the treble or bass tipped version. Again, you can get more bass from dynamic earphones. The SE846 bass quality is quite impressive - as well as being out of this world big.
I'm waiting for your comparison to the TG!334 -- still the best IEM (even the best earphones+headphones) I've heard.
