Thank you, this is much appreciated. When you have more time please tell us more.So, I've here now the IE800s and the Xelento.
I made a very short test and: don't know.. it seems to me that (sorry for the noob language) the Xelento are much more "open", "immediate" and "energic", the music is exactly "in" my head, while the IE800s are more "boring" and the music is "around" my head. I've to test it better but for now I would say that the Xelento to me sounds better.
Two flagship dynamic earphones for now
