Hello, i am looking to invest in a good audio setup for my pc. I currently have superlux hd681 evos with a modmic 4.0 muteless. I am planning to get the asus xonar dsx (for positional audio) and line out it to a fiio 11k. I have heard that the asus xonar dgx improves mic quality but it only has 5.1 channels. Can someone tell me their thoughts on this setup and also whether or not the dsx improves mic quality like the dgx? Thanks
