Ht Omega cards would more then likely be something that would work well for you.
Some of the Asus Xonar line is excellent for sound production as well as sound quality. I have a Xonar DX and while I cannot attest to its overall mixing quality and such, it does have excellent sound for movies, music, and gaming, and is not to expensive. For the Xonar line anything with an X in its name is PCI-E based anything without X is PCI based. Example Xonar DG is PCI, Xonar DX is pci-e, DX2 again pci-e etc.
The other option you have is to go to headfi.org and ask around there, they have extremely experience folks in sound quality be it recording, editing or what have you. I would ask there as well. Not saying no one here has valid experiences, but alas, alot of folks there are audiophiles as well as proffesionals in the sound industry. best of luck.
