Summary: The sound performance of this product is great especially for the price, but be prepared to spend a while installing it. I had some issues with the drivers for this card, be careful to install correctly and make sure to create a restore point before you install this.
Summary: I got this card to encode DTS for my surround receiver. It sounds good and hasn't given me any trouble since I set it up. However, getting to that point tried my patience. As is often the case, the included driver disc is out-of-date. That's not a big deal.
Summary: The driver has issues with win 8. Problems with PC sleep mode cause hanging issues. ASUS support says The driver is ok and does not care your problem. I also use Adobe Premiere Pro Cs6 to edit video and when you activate de audio hardware with ASIO64 you got endless clicks.
Summary: Sound quality is great compared to motherboard built in realtek "high definition" sound. Driver download and install from website is very easy in windows 7, other reviews have addressed the how to - ie go to device manager after hardware install, select the new device, update software, browse to...
Well, I certainly got a surprise from this product.

Summary: After being tired of on-board sound, and hoping for more out of a dedicated card, I turned my attention the Asus Phoebus. You can see my review of the product on its page. Not to be deterred, I decided to try again. Perhaps drop the budget and get a "mid" tiered card.
Summary: Works good for the price. Doesn't seem to have any functioning issues. Does what you expect and does it without any hassles. If you expect a GREAT card, then you have to spend a GREAT price. If you expect a CHEAP card, then you can spend a CHEAP price. This is right in the middle.
Summary: Haven't have a chance to try this out in games yet but there aren't any improvement i have noticed from listening to music. I have ASUS P5Q pro mobo and it is supposedly High Def sound so maybe that's why.
Pros: upgradable op-amp chip, low profile
Cons: No noticeable improvement from listening to mp3s
Summary: Not huge improvement on sound quality if you already have a better headphone. My Sennheiser CX300 headphone gives more result than upgrading this card. After I open the package I found finger printers on the product.
Summary: I had been using a preamp to digitize my LP collection on an old computer that blew up. This card doesn't have the blue line input. It claims that the first input works for microphone or line in. It works for mic but not my preamp.
