This amp has been collecting dust on a shelf for 2+ years since I don't use headphones much these days. I don't have the original screws for the case, and there is a scratch on the front corner (please excuse the poor photo quality). Also, the output volume is very low on my beat up HD-600's; I'm not sure why this is, but I imagine it would be an easy fix for someone familiar with this sort of thing. Asking $150 shipped.
