Need suggestion for the best all in one sound card @8.5k

Hi Guys i am intrested to upgrade the audio limitation. So suggest me the best pci e sound card. As my board if added second gpu i will be running out of pci slots so please suggest best future proof sound card worth investing. Also if that can have a front controller that would be an added advantage. Suggest the best price for the same.

Compliment that with good headset. 2k max

I have following in mind

Auzentech X-Fi Bravura Express audio processor
or
Asus d2x

I need Full hd audio pass through not downsampling.

Found these cards well handled that job

Xonar HDAV1.3 and Delux
Auzentech HD home theatre card
