i'm looking to improve the sound of my senn. eh2270's, the amp is a must, as their 64 ohm and i haven't found a portable source that can really power them, just looking for suggestions for cable/amp setup that i can get for under 100 bucks hopefully, but i'm willing to spend more if its worth it, but the amps gotta be portable, but an external power plug would be a nice plus as i'll use it off my audigy2 at home

i've read up on the cmoy and mint DIY amps, but i'm just wondering if there are better options, or any different op amps i should consider with these headphones then the ones suggested with those amps
