I intend to buy the S10, but as Creative claims, their Super X-Fi AMP is not compatible with the S10 series (all three models). They say that the S10s do not have asychronous USB audio mode working properly hence causing USB audio playback issues. As it seems, the same goes for all external DACs/AMPs.
There are also some reports that claim that the latest April patch has solved the problem. Casn anyone confirm?
