I am looking for an inexpensive sound card to amp headphones around 80 ohms. Dolby Headphone would be a plus (for headphone surround), but I don't necessarily need Dolby Live functionality as I am not planning to hook up to surround receiver to need encoding for optical out. Just looking to get better sound than standard on-board from Dell and also to power Beyerdynamic headphones. I would really like the headphone amp feature to work in conjunction with the front audio connector on my tower if possible.
Also I cannot use the Xonar DG as my computer doesn't support legacy PCI slots, only PCI-e.
