Off course French charm...how did I seduce aforementioned duck? Right now I am interested in the Hugo over the AK240 because at this stage, the Hugo is the only one that can truly best the 901 soundwise (I am just conjecturing, I have no idea).
I am not golden ears or anything. I know what sounds good to my ears, and so far, the X5 sounds really good with all my iems, and when switching back and forth with the 901, the difference is there, but not very significant.
Sorry for the OT, back to AK240.
