I'm waiting for a Geek Wave (I really hope it does make it for Q4 this year); meanwhile I've traded in carrying around a DAP & amp for a simple Clip+. My JH13 sound just fine out of the little player.
To go against the grain here, try the fiio X3. I haven't heard its noise floor with the IEMs I've used so far and there's enough power for fullsized cans as well. Plus you don't get the same possibility of buyers' remorse as with a 500+$ DAP.If you really must scratch that audiophile supremacy itch there's also the Geek Wave + IEM package.
