I just looked at price japan and I don't see them on there anymore. Just the 900's. Back when the 600's first came out price japan had everybody smoked on price, pretty much $1299 from all the U.S. vendors. Now I think allot of vendors have their hands on them and I think fostex lowered the retail price to $799 and the 900's to $1599. If you do go with price japan make sure you go with the EMS shipping as it is much cheaper and faster than DHL. If you can get a new pair for less than $799 you won't be sorry.
Thanks for the tip on the EMS shipping. I was checking out the options. EMS is indeed cheaper. The US retailers are listing it at $799 retail. Unfortunately, the Canadian dollar is hurting us at the moment and even then the prices seem to be high. With US, there's customs on top. Probably best to get it shipped to someone in USA and then have it shipped to Canada.
I'm really hoping the Dangerous Source will be able to improve the D2000 and keep them playable for some time until I can get the next headphone. The Source has two outputs, so I really want to have both the TH-600 and TH-900 playing from the port at the same time. Hopefully the sensitivity won't be too far apart for matched results.
