I want to be able to lay down under the stars (with a girl) while we both enjoy some music out of some HD650s.
 
What portable amp will have enough power? Should I think about splitting the signal or are there portable amps with 2 outs?
 
Thanks!

My Total BitHead from Headroom has 2 outs... but I don't know if it has the juice to run two 650's simultaneously.

My Bithead has no trouble driving my HD600, as well as my Grado SR80i at the same time (as liamstrain said, there are 2 outs).  I know that doesn't account for much, since the HD650 is harder to drive than the 600, nevermind just a pair of Grados, but for what's it's worth, it sounds great with both.  
 
Sometimes if I need my 600s really loud I drive them through my Bithead as well as a Fiio E6, which gives it an extra boost of volume (and I find the E6, unlike the E5, does not decrease the sound quality, but does increase the volume).  I know it's a little silly, but I already had the E6 laying around, and it's cheaper than buying a more powerful portable amp.  Just something to think about.

The iBasso PB2 can drive them easily and still portable but you need HP splitor with it.

Your girlfriend has HD650s? I think I'm in love.
