Oh dang.. Why did production stop? They're in my budget but they're too expensive overall for right now. I hope either they or their equivalent is around in a year when I look for a job.
MABJ's iDevice used for this message :p
I think it was just because Denon wanted to make more money. They released a new line of headphones (try a search for AH-D600EM), but gosh, they look ugly to me.
I'm not sure how long they will be around for, I guess it depends on their demand. Once the old stock is gone, they won't be getting replaced.
There are similar headphones to the AH-D2000, but they are more expensive.
