they said "The card has 3 swappable 8-pin dual opamps. The two matched I/V opamps impact the headphone out alone, while the 3rd "buffer" opamp impacts the RCA out. If you are only using the headphone out you only have to worry about the 2 I/V opamps." so if you dont use the headphone out, no need to change jrc's.
I don't know how sound DacMagic, i didn't have it, but looks like Wolfson WM8740 dacs (which use dacmagic) is lower level then BurrBrown 1792A, which use the asus in stx. so technically .... i'm not shore about which one is better, mby in some way another sound..... But for me the good one thing for DacMagic is balanced out (xlr), which Asus didn't have at all

in another forums some people recommend (if possible) to use ASIO to pass through windows built in mixer. All what can i say after some time experiments, if possible, use ASIO4ALL it's awesome thing! http://www.asio4all.com/ÿ

(im using lossless audio formats through foobar2000 through ASIO v2 and listening on Genelecs or DT880).
sorry for many time editing. wroting this post i was experimenting on my stuff, reading lots of reviews and try to make out the best.
