I should have been more clear in my post. It depends on which version of the DT990 you get. 32ohm, 250ohm or 600ohm. 600ohm is easily the best but needs at least an Fiio E9. 250ohm probably a Cmoy. 32ohm I have no clue. Honestly anyone looking into DT990 should just go 600ohm or get something else altogether.
p.s. I have the HD600 and HD650 along with a bunch of other cans. Both sound rather bad out of an iPod but probably better than the Beats still... The only 2 I have that I can't tell the diff with or without an amp is AT A900 and AD700. I agree though sound is relative and it is best to try it out yourself if possible.
