I have a pair of HD-280 Pros and a macbook pro. I'm looking for a portable amp that would work decently--> well with both applications. I've been looking at the bithead but not sure if that's the correct choice.
 
What are your thoughts? I would like to get a little bit more bass out of the HD-280s (they've been burned in).

You want an amp with bass boost.
Bithead doesn't seem to have that.
