THe Xonar D2 isnt bad at all. IMO, it is the better choice, esp. if you put more emphasis on music playback... Although both the Xonar and the Prelude are very good and difficult to distinguish in real-word listening session. But as pointed out, both would be a waste of money, if you dont have good amp / speakers to go with them.
As far as stability and compatibility of the Xonar - very good, no problems so far. Havent used the Prelude extensively to comment on it.
btw, here a review i found recently, could be useful - Remixed audio cards in Windows Vista - The Tech Report - Page 1
