If you are looking for a tonally bright headphone, the Grado's are the way to go. Upfront and narrow soundstage. However they still IMO lack build quality to that of other manufacturers.

If you want something that is very analytical but more refined and with a better soundstage, the Beyer DT880. Better build quality too. They come in different ohm versions.

If you want something that is less analytical but still detailed and has an excellent overall warmth check out the Senn HD 600 or Senn HD 650. Excellent comfort and soundstage too. The best option if you are sensitive to listener fatigue.
