The Dulce has a distinct coloration that people will probably either love or hate. If you like bass and warmth, as demonstrated by your love of the TH900, then you'll probably be one of those who love the Dulce.
Dulce does sound like it would be right up my alley, too bad I don't have a chance to test them out anywhere. I am visiting London shortly at the end of August, maybe there's a place I could test out the universal models? If I do end up with Dulce, I'll probably also pick up K10 (or a successor if there's one coming) at a later date.
