These facts by bigshot is actually something
most head-fi'ers should be aware of, but unfortunately, too many on this forum waste their time and money on exotic mp3 players, expensive DACs ect (EDIT: this includes myself
).
The iPods have DACs that compare to good standalone home CD players. Every one of them has stone flat frequency response, no distortion to speak of, and a noise floor WAY below audibility. If you're hearing differences, you're eiher comparing the iPod to something that has inferior sound, or you're hearing placebo.
I have tested this myself. I own several iPods, from different generation. If you ABX them against one another or against a CD player, you will most likely not be able to tell them apart!
Another good fact:

You aren't hearing soundstage. You're hearing better frequency response or lower distortion and you are subjectively describing that to yourself as "space". The cues that create the illusion of depth are slight reverberation or echoes caught by the mikes during recording, or phase filtering done during mixing. Those aural cues are in the recording, not the headphones. Better headphones just reproduce the sound more faithfully, and those subtle aural cues can be heard better. That isn't soundstage, it's clarity.
The difference between good headphones and apple earbuds is clarity (low distortion, flat response) not soundstage.
What people usually term "soundstage" for headphones is often just clarity. Though, some headphones have angled transducers (sennheiser HD800 come to mind), which might affect the way the sound is perceived.
The headphone "soundstage" can be dramatically improved if equalization is used to obtain an audible flat response. If you try this yourself, you will realize that "soundstage" in headphones is actually just clarity; eg. low distortion and audible flat response.
