I had a rare Lehmann Black Cube Linear for sale. I had this since last year. I use this one with my hd650, I am selling those gears for funding my active speaker. If you purchase the bundle I will give you 900 for them all. Hd650 pairs with lehmann very well, I am pretty satisfied with this comb when I was using it. coming with original box, I will give a free power cord and rca cable.
