I love my headphones. I buy em. I use them. But most people don't really go the extra step in getting amps to really make their Cans pop. So, start with this video as a basic run-down for what you need to look for in an amp.
Go to Headphone Power Calculator (http://www.digizoid.com/headphones-power.html) to check on the specs of what your amp will need as far as power goes. If you don't know the exact specs of your make and model, head over to Specout (http://headphones.specout.com/) to look up your make and model. And yes, I'm currently in the market for an amp. I've used a cheap version from Radio Shack in a pinch when I didn't have the time to research for something a bit more substantial. It's a decent amp. But now I'm look for something that has more power and more bells and whistles to play with the overall sound.
