hi there, my feedback thread is available here: http://www.head-fi.org/forums/f12/leeperry-407556/
I'm selling a Sony MDR-CD900ST, hardly burned in and totally mint. Sony say that it's using all their headphones technology: http://translate.google.com/translate?l=en&sl=ja&u=http://www.smci.jp/MDR-CD900ST/

You can read nikongod's opinion about the cd900st at the end of this thread, together w/ some Japanese cd3k owners opinions as well(they say that "it lets you hear each tree instead of hearing the forest"): http://www.head-fi.org/forum/thread/310323/slight-cd3000-refurbishment-not-too-56k-unfriendly/45
They are impossible to find second hand, but when you do the fact that basically nobody outside of Japan knows what they are drives the price down. "a hopped up MDR-V6, I burst my side laughing"
If you find a set second hand get them.
another review from another R10 owner: http://www.head-fi.org/forum/thread/506199/sony-mdr-r10-what-is-the-fuss-about/60#post_6881378
and there's a quick review here: http://jaben.net/forums/index.php?topic=7587.150
It's indeed a very unforgiving cans. So far it the most transparent and neutral cans I've heard.
and here again, from the same author, comparing it to an Edition9: http://www.sgheadphones.net/index.php?showtopic=9338
They have an even wider SS than the HFI-780 to my ears, sound very neutral and make the cd3k sound colored. Isolation is also very good, they use a much higher drivers grade and thicker earpads than the MDR-V6, only sharing the same shell.
I'm willing to let it go for $OLD shipped worldwide via insured/registered priority mail. I will declare a low customs value so you won't have to pay for import taxes, and will include another pair of earpads that fit perfectly and are a bit thicker/wider(they come from a CD999).
