I recently got my hands on a pair of Sennheiser 25-1-ii headphones for Christmas after much begging and offering to reimburse some money and I'm just wondering if there is a cheap amplifier that would be around 100-150 dollars that i could plug into my headphones and ipod/iphone into! (it doesn't necessarily even have to be portable, I'm just assuming most in my low budget price range will fall under that category.)
One side note, i mainly listen to techno (dubstep/trance/electro) - included this because I'm thinking it is important to deciding on an amp!
thanks in advance for your time. :)
