Reply to Ultrasone DJ1 Pro VS. Pioneer HDJ-2000

I've read the several post's about headphones, most of them were before the Pioneer HDJ-2000's were actually available.

*** PRICE IS NOT AN ISSUE ***
Please don't comment about price... I don't care.

Has anyone actually used/borrowed/demoed, or owned the new Pioneer's?
I've read several very positive reviews of the Ultrasone DJ1 Pro's. The only bad thing I've read is someone went through 4 in a 4 month period because the joints were breaking. I currently own the Sony MDRV-700DJ's I've repaired the joints on these severl times. Having read that the Pioneer 2000's have metal joints realy makes me lean that direction, BUT the Ultrasone's seem awesome too. Note: I like that they come with two cords, one with volume adjustment.

So, what do you guys and girls believe??? HDJ-2000 or DJ1-Pro
