32 Ohm versions of DT headphones are probably not the best deal, specially if you will also buy an amp. Go with a higher impedance version.
DT880 are quite light when we talk about bass and won't fit the genre very well (imo) (This are neutral headphones with forward mids)
If you want powerful bass, DT770 80 is the way to go, but custom one pros also seem to be a good pick.
E11 will drive 80 and 250Ohm Beyers just fine. E12 is better. For the money you should also consider getting a fiio E07k or E17 (DAC + Amp) instead.
