A lot of us need to have headphones in order to listen to music; either we work in an environment that doesn't support louder music or we just want that in-your-ear closeness for deep focus. With the advent of compressed music and extreme portability, it is unfortunately getting harder and harder to find high fidelity out there. Thanks to the folks at Grado in Brooklyn, NY (They were there before you had to prefix the word "Brooklyn" onto things to make them cool.), we have a nice solution that can fulfill our needs on a very intimate level.
A cnc machined mahogany case surrounds a very simple circuit which gives most any headphone an extra kick of power and 'quality'. We have talked about Grado Headphones in terms of looks and sound in the past and this amp's quality is in the same strata. Pick one up for the only slightly high price of $350. Battery (40-50hrs) powered so you can impress at Starbucks or Micky-D's or where_ever.
