I have all original packaging for it. Fantastic solid state amp that unlike something like Jotunheim does stage depth well. Is fast and clean and neutral and works great with a variety of phones I threw at it, from hd800/650/600 to ZMF cans to old school hifiman. It even did pretty well with he6. Asking $300 net. 2) Selling a modded hd580 by none other than our local Sennheiser wizard billP. These hd580 have the 650 grills, and extremely nice and pricey Sennheiser HE60 Orpheus pads which feel amazing. The pads alone are $100 from Sennheiser and not easy to get. Together, the mods make the hd580 have an extremely even frequency response. Asking $165 net.
