I've got an Asrock Extreme4 Gen3 P67 and haven't really been pleased with the onboard Realtek audio. I've got a Logitech 2.1 speaker setup and also use basic Sennheiser HD 201 headphones. Pretty basic/simple audio hardware and I'm obviously not an audiophile. I've seen really good reviews for the Asus Xonar series of cards and was leaning toward getting the Xonar DGX. Due to an issue with my front audio panel, would it be possible to split the rear audio out between speakers and headphones without losing quality? I'm not sure if the DGX card has a headphone amp built-in, but if it does, would that help?
