I stepped up from the Grado 80 using the headphone jack on my Radio Shack Optimus CD-3400 to the Sennheiser 600. Everything got much better, although I might like a touch more bass. I am now using the Berning micro zotl and the sound is simply terrific. It is amazing what I can hear that is lost through any speakers. The Grado might be similarly capable, but if you can sit with the Grado on your head for two hours you are a better man than I.
