So I think I've come to a conclusion after much deliberation and research. I am going to try the DT 990 Pro 250ohms and get the Fiio e11 as a portable amp. These should work with the ASUS Xonar Essence STX I plan on buying as well. I feel that if I order them and don't like them I can always send them back. I do truly appreciate all of the help from each and every person in this thread. The DT 990's seem to be the best fit for me considering the price as well. It'll probably be a few days before I get a hold of these bad boys, but when I do I'll let everyone know what the final consensus is.
Try the third party drivers "Unified Xonar Drivers" at the website Brainbit.
