Titanium HD, Auzentech home theater, X-fi Forte,HT Omega Claro II(uses same processor as Essence STX), Claro Halo XT, Claro +, Xonar Essence STX, Xonar D2X or the one I am using, and love, Xonar DX.
Generally speaking ASUS Xonar Cards are the most well rounded, they tend to be the best overall for music/movies gaming, Creative is gaming//movies/music, Auzentech gaming/music-movies, HT omega are near parity to ASUS but are a touch better for gaming side(in regards to thump and such)
I like the Xonar cards, as if you are using Windows 7 or vista, Creative type cards only have so much extra features they can do without using odd workarounds, from a pure spec wise, example SNR, the ASUS cards tend to one-up thier competition, Thier drivers are not the greatest, this is true, however, I have had the DX now for well over a year and still works awesome, as good as I want it to, the drivers work well(now) and from my understanding, the Xonar D2X or Essence ST/STX would blow this little card out of the water.(but I didn`t have a few $100 to spend on a card or I would have went with the STX)
Just one quick example, SNR, I believe SNR for most "decent sound cards" are 109-114 db SNR, most of the Xonar line do around 114, the higher end ASUS cards can do up to 124 so they do tend to have more ooomph, but are pricier, though they do tend to have some of, if not the best circuitry and such.
I do not know youre needs as far as Dolby, encoded and all that fancy stuff, I would take a look at Xonar offerings or HT Omegas and see what best fits with your direct needs, I am sure, one of the Xonars will be what you are looking for, btw the Xense is not worth it from what I have seen the STX most certainly would be the better choice, however, the Xense with the optional(and $) headset is apprently pretty damn nice for music/movies.
