What kind of sound does the AKG K612 have? I mainly listen to rock and acoustic music. 

One more question, what's the difference between the DT880 Pro and Premium versions?

I recently just got the DGX so I don't think I'll be dropping another $75 for an external jack...might just go with the 250ohm version for a few months and until I can spend more money on an amp. Thanks for the help :) 

Any recommendations on a cheap amp that would drive the 880s? 

I live in Canada, so not everything on Amazon ships here. Unfortunately the DT880s don't. There's a retailer here that sells DT880s for $250. Do you have any experience with the DT770s? I just know that they're closed headphones, but they're much cheaper and Amazon ships it to Canada.   Quote...

Ah, so I guess I should go with the 32ohms? I'm currently using the ATH-M50s, any idea on how much of an improvement the 880s will be? 

Hey guys, I currently have an Asus Xonar DGX sound card on my desktop PC. I'm thinking of getting the Beyerdynamic DT880s, but I've heard that the 250ohm version sounds much better than the 32 ohm version when amped. Will my sound card be able to handle the 250ohm version or should I just go for...
