Both are in my price range and I can't decide.  I own 7500+ CDs with some in almost all genres, my favorite styles right now are Americana, bluegrass, blues and indie folk, but I still listen to a lot of progressive rock and fusion jazz.
 
My main set up uses a Woo Audio WA2 and my bedroom set up uses a Marantz CD-5001 (with built in headphone amp)
 
I currently have a pair of Thunderpants TP-1s and a pair of Grado RS2s that I listen through and I like them both, although the Grados aren't suitable for long listening periods due to discomfort. 
 
I want a comfortable pair of headphones that are really good with acoustic instruments, but that I can still use to rock out with.
 
Suggestions and reasoning would be appreciated.

I won't make a suggestion as I haven't heard either of these personally, but those are two very different headphones.  The nighthawks are a darker sounding headphone while the hd700 leans a little towards the brighter side of neutral.
