I am the original owner of these AH-D2000 headphones. They are complete with the original carton and paperwork, and I've made all the individual Markl Mods to the headphones except the hole-punched Dynamat on the front of the drivers. I used Dynamat Extreme for the cups and the circular strips on the back of the drivers. The earpads are stuffed with fiberloft and held in place with the rim of the 3" plastic cup, as described by Mark L. in his excellent description on Head-Fi. The 1/4 to 1/8" adapter is included.
The headphones have been burned in for 120 hours with alternating pink & white noise, frequency sweeps, and alternating music of various styles. I estimate I used the AH-D2000 headphones approximately 25 hours after the burn-in. They are in excellent condition and sound great (especially after the mods), but I prefer the sound of orthodynamic headphones and must sell these D2000s.
