Of course the better gear you get the better results you can get, but I have the AirHead and prefer it by a large margin to just the iPod. Sure you can get the same level of volume with the iPod, but remember, amping is not about volume, so much as control of the headphones drivers. So even with all my Grados, SR80, SR325is, and RS1i I still prefer a amp at all times. If you get an AirHead, listen to it with your iPod as a source, (Lossless of course) for a month or two, then go back to listening straight from an iPod, I'll bet you'll hear a definitive step up and down between the two.
