I have tested and reviewed many Xonars up until this point and I have always found their drivers to be easy to use and stable. In my opinion this card is aimed at audiophiles using stereo speakers or headphone nuts. Many people when switching to headphone will find their favorite cans usually "high end" cannot be powered by a sound card alone, they need a external amplifier. This card can power any current headphones using built in headphone amplifier with driver settable gain ranges. This card is very impressive based on what we have seen so far.
