Im not 100% satisfied with the shipping, thus the 4 egg overall experience. The product itself functions exceptionally. It is a 5 star audio card. I definitely recommend it for an htpc build, for watching movies and listening to music.
i got it on sale and am pretty happy with it; On krk rokits, corsair sp2500 and bland creative t40s, the stx makes quite a difference in sound quality; highs, mids and lows become very distinct; It offers a plethora of settings to enhance your music and movie experience.
asus software interface looks outdated. Not a huge deal, since it's mostly a set it and forget it affair, but it just looks windows 98 ish. The extra clarity works both ways; lossy and unprofessionally mixed audio files will become much more apparent.
