Hi all. Just picked up a pair of AKG-7XX from a user here, which is plugged into my Yamaha DSP-A1 receiver, connected to my computer (no soundcard, straight to mobo). I enjoy the headphones, but I feel that the sound could be better, as the highs are very harsh sometimes. Should I consider...

Mine: I received my Sennheiser HD448's and Fiio E11. Plugged in my iPod and headphones, and played the first FLAC I could find. I just sat there, listening, in awe about how much more amazing my music sounded then.    What about you guys? What was your "first time" like?    

Hello all. I reccently bought a pair of HD 448's. I'm going to be using an iPod Touch 4G and the iPod Nano 6G, and I was wondering, should I buy an amp? And if so, which one? My budget is 0-100 dollars.
