Hi all,
After going to the NYC meet I figured it was time to start to think about upgrades. Right now I'm running a FiiO X1 into my Grado SR80i or Shure SRH440 for at-home use, SE215s for when I'm out. I enjoy the openness of my Grados, however, I'd like something with a bit more isolation (for around the house- not looking for a new portable set yet). I'd also enjoy a bit more warmth or at least neutrality compared to my Grados; I like the sound signature of my SRH440, but something with better sound quality and maybe a little more bass would be appreciated, as well as a better soundstage. Also, I'd like some kind of amp to improve upon my FiiO X1's; I thought the E11k, which I tried, added a bit, but something adding a little more clarity may be nice. Overall I'd like to spend no more than $300, maybe $350. At the meet, I really enjoyed the Stax Lambda, ZMF Blackwood, and MrSpeakers Ether C.
 
TL;DR:
Looking for:

1. Warm/Neutral headphones, good soundstage
2. Closed, with decent isolation, preferably comfortable
3. Used for rock, electronic, pop, & more
4. Amp to improve upon FiiO X1's output
5. Totaling no more than $300-$350

 
Thanks for reading and for any responses.

You should consider the Focal Spirit Professional.
You could also read about the Soundmagic HP-150.

I've heard a lot about the Focal, and only good things; they're very interesting, but also a bit pricey for me. I'm looking into the HP-150, which I've heard a little bit about. Thanks for your help.

Gonna bump this real quick just to see if there are any other suggestions.

Does anyone know anything about how well the new Fostex Tx0RP MK3 line would fit what I'm looking for? They seem to be a good fit, though I'm not sure which one would be best (T50RP?) and what amp would pair well.
