Well, I'm a total newbie to all these and I came across amps when looking for headphones. So I've got a A-jays three and Sansa Clip+ and I was wondering if adding an amp will do any good? If so, I was thinking of the Fiio E6. And then there is also the Madcap Penguin amps which look so friggin' cool. But what's holding me back is the cost of the amps. (since my earphones don't exactly cost alot) Hoping to get good advice from you guys
