I would go with the Fiio E17. It's VERY versatile and sounds great while capable of driving higher impedance cans. Just cut out EVERY possible expense for the next couple of weeks and you can swing it. I plan on getting a pair of DT 990 Pro in the next few weeks and then getting the E17 if my 2 current setups can't drive them.
