Xonar U7, because the FiiO E10K has none.
Just a DAC like the E10K would be reliant on separate software for positional sound placement.
You do mention being able to place sounds with just stereo, in player unknown. It could be that that game has built in positional algorithms, so less need for Dolby Headphone or SBX.
It's probably more common now for games to have that built in. Those games that don't, you'd need to use Razer's surround software with a E10K.
U7 being a sound card, has a microphone input. At least you'd just need one device then and not a DAC/amp for headphones and something else for microphone input.
