STX would work just fine. But again, depending on how loud you listen, you might be able to just use the D2X directly. I would at least try that before buying anything else. That's not perfectly ideal, but neither is spending a significant amount of extra money. Didn't you want the DT 990 Pro because it was cheaper?
If you do get something, don't you already have a D2X? All you need is a reasonably-powerful headphone amplifier. Unless you really insist on having nothing external and plugging the headphones into the sound card in the chassis, you can just connect the sound card to an amp and the headphones to the amp. Granted, cabling would be a little messier if you really want to use a clip-on mic.
The integrated amp in the STX is mostly similar to the one in the FiiO E9, by the way. Getting that would be cheaper than an STX. If you ever think you might want to use certain lower-impedance headphones or sensitive IEMs in the future, an Objective2 is a little more expensive than an E9 and is better for those tasks.

At a lower price point, some type of dual-battery CMoy variant may be okay. It depends on the design.
