Unit was defective, build quality was cheap. RMAA results were horrible (worse than an ipod or old AC97 onboard audio), when the left channel was actually working. Elaboration @ http://www.head-fi.org/forum/thread/474294/ha-info-ng94-mkii#post_6718628

I love this card, but since it's taking cmedia years to make properly functioning Windows 7 drivers, and and ASUS is failing at making proper asio drivers, I'm going to have to part with it.   The card still picked up some noise from my gpu (less than onboard did) during gaming - all internals probably will - if you're not going Auzen x-fi, stick to external DACs.
