Very nice sound (clear). I used an entry level sound card before that: there is a huge difference.
Same remark: there is a thump if the amp gain is too high when starting.
The 24 bit crystalizer is not ok for my system: too much treble picks(not comfortable to listen).
It comes with a fully configurable tool but unfortnetly, it is not documented!!
This card is amazing. I went from integrated to the X-Fi and it is CRYSTAL clear. I have virtually no static pickup through the analog signal compared to my integrated I ran earlier. The 2V RMS seals up the deal. The 24bit crystallizer is working great for me. I do not have any thump on startup.
I have a problem running bass to my sub amp through the sound card when the card is in 4.1. You have to be in 5.1, but if you dont have a center channel it will sound crappy. This is the case with most 5.1 cards anyway..just FYI. It took a while to get everything sounding how I want it to but I do have to say this card is worth it.
