What source gear are you guys using to drive your JH16's?
I've just bitten the bullet on a pair of JH16's which will be my first CIEM (upgrading from a pair of lowly SE215's!), but now I'm starting to think that my portable source rig is in need of upgrading. I currently use the SE215's unamped from my phone or tablet (Nexus 4/7), but am thinking about getting a dedicated DAP - I'm currently looking at Cowon players for their decent battery life and sound quality, even though its not really considered an audiophile DAP. However I am wondering whether it is worth getting a portable amp as well, or whether I should forget the DAP and just get an amp to run from my phone/tablet? I know the JH16's are very sensitive and easy to drive but one of my concerns with that would be the output impedance of my source as I want as little background noise as possible.
The Fostex HP-P1 works great with the JH16's.
