Pros: Sounds great so far, improved the bass and treble over my last DAC, a Fiio E10. Front audio jack support is very nice for IEM's and short headphone cables; I use it due to my Sennheiser HD25-1 II's short cable. I will update this review with more impressions after 100 hours of listening (or submit a new one).

Cons: The software has a lot of extraneous features that don't really add anything. It concerns me that these extraneous features could affect the sound in a negative way in the future. It's also pricey at 180$, almost as much as I payed for my headphones.

Overall Review: I just wanted to say that the drivers worked fine on the first install for me, no problems whatsoever in Windows 7. I see several reviewers saying there aren't even any drivers, but this is very apparently not true. The driver support for this card is just fine, if not excellent, in Windows 7.
