Well I have good news and bad news for any new users of this card.
First the good news: If you wish to fully exploit the full features of this card as a home theater user with a proper audio set up look no further than to the
Emotiva Audio A-500 BasX 5-Channel Power Amplifier. This is a true bare-bones power amplifier that will grand excellent excellent sound quality and less than 0.07 THD on the "cheap". At only $400 to $500. If you pair this sound card to this amplifier and some decent passive 5.1 speakers, then you will have amazing sound quality for the price. You would have to pay thousands of dollars in order to beat this set up with the regular receiver + speakers combo.
Now for the bad news:
MAKE SURE to buy this sound card with its daughter board! Don't be a sucker like me who just bought the sound card by itself and now can't find the
ASUS Xonar H6 7.1 Channel Output anywhere in the internet. =(
Can someone please help me find this sound add on card? I am out of ideas. It seems Asus is not manufacturing this add on card at all. In fact, if you search the web for "Asus xonar Essense STX II" you will only find the stand alone sound card without its daughter board; you actually have to look really hard for a handful of sellers that offer the complete package at an inflated cost.
If worse comes to worse I might have to sell this card and replace it with something else, although at this point I am not even seeing new sounds cards coming out, the only other worthy replacement to this card are the HT Omega cards.
Edit: It seems that the only other worthy replacement for users who want a home theater system would be the HT Claro Halo XT,
