This is an incredible all in one for headphone useage. Currently using it with my Sennheiser HD-800s, 700's and Kef headphones. Not a mark on it that I can see but will rate it a 9 to be safe.
Seems to be a lot of flaky buyers right now so if you make an offer via email or formally that I agree to, follow through! If I accept plan on paying immediately. If you have no feedback (bulk of my problems) please send me a message first.

No box but I will pack it better anyway. Feedback speaks for itself.
