Note: I'm not to experienced or knowledgeable about amps so please excuse me if I make a stupid.
Okay, I was originally going to just get an e6 but I realized that I wouldn't really use it much for on the go. Now I'm wondering what would be a good amp (or DAC whatever) for at home use and occasionally portable use to improve sound. The source will be my PC (not sure on the sound card or anything) and an ipod 5th gen classic. For headphones I have HTF 600's (which don't really need an amp) but I plan on soon getting k240's which kinda need an amp. I know this may sound not good but my budget is around $60 (it was $30 for the e6 but I decided to just save more for something better). If I don't end up getting an amp or something I plan on buying another set of headphones (if that would be a better idea) most likely the Beyer DT 235s.
