A lot of people may disagree - but personally I feel like you'd do a lot better going $200/$100 Headphone/Amp respectively, or $250/50. Whatever really.
Even my extremely efficient cans don't blossom until I hook them into at least a portable amplifier. It may just be me, but I can't get on board with unamped cans, especially not while a FiiO E11 or something of the likes is attainable for only like $60.
You may want to check out some DT990s though, they're great efficient headphones and have the oomph for electronica. As long as isolation isn't an issue.
Agree completely with that first statement. You would always be better off with a slightly cheaper headphone and some sort of headphone-specific amp. And no, as a MOT, I don't sell any amp for less than that and I would still say the same thing. Heck, you'd be better off with a CMoy and a very slightly cheaper headphone than without. It's how I started out ... just MHO.
