Yeah, you're right about the "personal liking and taste". Headphones like the Xelento are something new for me then I always had Sennheiser all my life. I'm torn because I don't know yet what I exactly "like": soundstage or not? The Xelento are just more energic and immediate for me, I have more fun with that.. but the IE800s are spacious, I can define the instrument in the space etc.. and that is why it lost the quality of the Xelento. Maybe I need something new, maybe I just what an intimate sound "in" my head. I will decide me over the weekend but for now I prefer the Xelento.
