I am selling a pair of mint condition Denon AH-D600. I am the second owner. The first owner rarely used them - they show almost no signs of use. All original paperwork, cables and box are included. I would consider trades for Hifiman HE-400, Beyerdynamic DT 880/600, Senn HD 650/6XX (plus cash on my side) or send me offers. No IEMs please. Shipping and PayPal included in price. CONUS only.
