Pros: Cheap, works, swappable opamps.

Cons: None. I hear Auzentech support can be sketchy but haven't needed them yet.

Overall Review: After swapping the front L/R opamps to OPA627's at a cost of fifty bucks, the sound is just lightyears ahead of anything else in the sub hundred price range. Very highly recommended, at least for 2 channel use. I suppose it could get pricey upgrading all 8 channels.

Pros: Excellent for a silent card but it does require case airflow or it will overheat.

Cons: You can't run this card with an open case since there will be no air flowing across the card. Not going to ding it points for something that someone buying this card should know to begin with.

Overall Review: A bit pricey but no more so than buying a 9800GT and adding an aftermarket cooler to it.
