[Audiophiles] What kind of Headphones/Amp do you run?

[NPragz]

Just curious as to what everybody prefers. I've been using my FiiO e17 for awhile, with my Audio Technica AD700s, but I'm thinking it's time for an upgrade. I love the open-ear sound stage, but I could use a little more bass in my listening.

Could anybody recommend what they think I'd be interested in? I've looked into the AD900s, and they do peak my interest.
