Can anyone give a comparison between the ATH-AD2000 and these headphones? I don't have a lot of references to compare to. I'm assuming these will be more neutral and less forward in the mid-range, and overall on the brighter side? Any insight is appreciated. I got the headphone bug that only seems to get me every 4-5 years or so and wanted to try out something new, so I ordered the buydig DT1990 bundle with the 15% off eBay promo and will have in a few days. The bundle comes with a HiiO A5, a hardshell case, and an SD card for $501. I had another eBay promo and got a used A20 for $175. I'm hoping this delivers results that will give me the same kind of feelings I got when I first heard the AD2000. Not the same sound signature, but the same kind of novelty and urge to re-listen to a lot of material.
