Dude: "research" is not reading every opinion you can on performance, taking everything you're told at face value and trying to come to some internal consensus about what to do. You have to have some means of weighing what you read and developing a sense of judgment and a useful sense of scepticism. The important thing is understanding how someone, the opinion-giver, came to their conclusions. Here, you can expect informed answers backed up with evidence.
You didn't waste $200 and your current headphones are excellent—so excellent that they are used in studios for mixing music.
For example, this is how I would judge the stuff you read about the Xonar DG:

- I searched for and found these specs posted on the Asus website and these measurements made by a reviewer. However, both are not useful indicators of quality because the test rig and measurement conditions aren't described. Armed with this knowledge, you can safely throw out almost every listed performance metric that's thrown around as simply uninformative. (To understand why please read this note by Rane, which states which conditions need to be stated to make measurement results meaningful and comparable to others. If you don't understand even after reading, that's fine, but then you also have to admit to yourself that you don't know enough to come to a conclusion.)
- Amir made this review of a Asus Xonar U7 Mk2. Output impedance was measured at 22 ohms. This means headphones of less than 200 ohms or so will show frequency response changes. Given the weak heaphone amp module, 5mW at 300 ohm and 22mW at 33 ohm, this means that neither you nor most other users can even use high impedance headphones. Despite that, the audible changes aren't something people can detect unless they know what to listen for, in other words, unless they are trained.
- The conclusion I would reach, on the basis of measured information and without ever listening, is that the Xonar DG (apparently $70 on Amazon, or maybe $45), and the more expensive Xonar U7 MK2 ($90 on Amazon), are both bad choices for someone who cares about sound quality. Aside from the output impedance issue, weak headphone amplifiers will be driven into clipping when listening and will easily produce audible distortions for those who know what distortion sounds like.
- By the way, as a side note, listing dB versions for the Xonar DG is an incredibly misleading and wrong way to advertise a product.
Finally, listening for audible differences in electronics as a test of their quality is a waste of time. Quality tests are done with gear. Go with the numbers and learn what they mean. Learn to slow down and admit that you don't know, and learn to not get hung up on the judgments of others. Otherwise you will be stuck trying to decide whose opinion you trust more, which is not the right way to make decisions.
If any of the above is unclear, please ask.
When a person is obviously young and suffering, it's best to just be patient.
