Recently, I checked the specifications for my Shure srh440 headphones and realized that they are considerably underpowered by my ipod (old nano). I decided that I'd buy a portable amp for commuting to and from school with my ipod. I usually use the Shures to listen to electronica and the Gados for classical music. Ideally I'm looking for something around the $100 range. (Student budgets do not go well with being an audiophile). Also as a side note, I find that neither of these headphones have a very powerful bass and I would like an amp that could bring that out without sacrificing the mids or highs. I was looking at either the Fiio e11 or a CMOY. Any other suggestions?
This is my first post here guys so please go easy on me, thanks.
