After having some issues with a Creative ZXR (The infamous channel swapping bug with PCIe PLX chips), i decided to try this. Most people raving about how much better the drivers are.

The card come in a flashy package (typical of Asus), the Creative ZXR is more solidly built, but the STX uses the exact same DAC, i was not expecting much difference. But in terms of drivers, the first message i got is "Choose not to restart the computer, some functions may cause no effect, please restart the computer later". They obviously speak a different English than i am used to, but heck, this is just a warning message. So just rebooted. After i tried to play some music, its not bad, but its definitely flatter than the ZXR. Much flatter (and disabled all effects on the ZXR). Well see how can i tweak these, but lets move on the next item. There is no 5.1 surround over analog speakers. Nada. None. There is only one configuration for 5.1 is with side speakers, there is no way to get 5.1 with the classic 2 front, 2 back, 1 center, 1 subwoofer. This card only does 5.1 with two side speakers, only 7.1 allows me to use rear speakers.

The drivers are a joke compared to Creative's. This is what most reviews praised, but after the ZXR its like going back to the stone age. It looks like a Windows 3.1 application, miniature icons, no settings, apart from the stock CMedia options (this card is powered by an archaic cmedia chip)

- Its not recommened for gaming (i am sure they could improve it with drivers, but if the Xonar Phoebus is any indication, it probably wont)
- 5.1 speaker support is flaky (i could get it to work in 7.
