I've decided to buy the beyerdynamic dt770 pros, their the 250 ohm model (I can get a good deal on them), but I'm curious if my Fiio X3 will be powerful enough. I believe I've heard that it's supposed to be a slightly improved version of the E17, but I'm just looking for a more experienced opinion.

I had the DT-990 250 ohm, and they weren't that hard to drive. You are probably fine.

Ah, thanks mate!
