The card is allowed to take 25W from the slot, much more than any normal amp would use. The PCIe slot is more than sufficient to power both the card and the amp it holds.
The difference is not the volume only. My DT 770 250 ohm on my z sounded totally different and anemic compared to when I bought my zxr. The zxr can definitely power 250 ohm cans sufficiently.
And the zxr does 50 mW into 600 ohm not 250 ohm. At 250 ohm it will deliver enough power for your DT 990. I wouldn't worry. The headphone amp in the z/zx can't put out the same power however I never had the distortion problem, that typically is a driver issue. The maxim headphone amp in the z only puts out 125 mW at 32 ohms so at 250 ohm it would definitely be below what's needed.
Best bet is to try your headphones on a different amp and see .
Why did you return the ZxR and went with the Z?
I didnt, I sold my Z and bought the ZXR. I initially wanted the ZXR but it was not available near me so I went with the Z to see if I liked the software studio and support for older games. Once the ZXR was available, I jumped on it.
I had the Stx, and as I mentioned before I'm using DT 770 250 ohm
I noticed a huge difference with the zxr. Its a lot cleaner, less bloated bass and the highs don't Peirce my ears like with the z , they are smoother I guess I would say. I feel like its a more neutral sound in comparison. The z seemed warmer. Also it seems to power my DT 770's much better especially since they are 250 ohm.
But for sure the clarity was a difference. If you compare the line outs then it might be less of a difference but the headphone out on the z isn't as high in snr.
If you aren't using high quality headphones then the would be fine I guess. At the end of the day its all how u perceive the sound.
Part of me also has this ocd where I have to have the best.
I would definitely say zxr because at this price range will never find a better DAC/Headamp combo. However if price is not a problem then there are way better amp, dac's out there especially if you want to build your own or mix and match.
And if you want the gaming features and surround then zxr is really your only option right now. Plus its 1 device neatly in your PC and you dont have to have a chain of devices or sources lying around.
