I should also mention that this set-up will be primarily used for listening to music (from light rock to harder edged metal; no rap). Keeping that in mind, I'll probably also use it for movies, etc. on my computer. I'm also a musician, so the headphones will see some studio use (although I doubt that will make any difference). Another consideration for the headphone amplifier (which is where I'm virtually cluesless) is the FiiO E7/E9 combo, which I've heard gives some pretty good on-a-budget sound with a decent set of cans.
