I checked and I didn't find any besides that outrageous French one. On eBay, Monoprice sells it new but open box at 440 USD, but with customs and shipping it would end up at around 620 USD, ~523 euros which isn't that bad, although there's two things:
1) I don't know how the warranty would be. I don't wanna be in the same pickle as with the CTH, in which it started giving issues shortly one year after.
2) Honestly? I would rather take my chances and buy it "ilegally", paying customs only if I'm caught, but I believe that using eBay US (or Amazon US) would imply paying customs beforehand.
I will keep looking, I really like the CTH sound, but I've got really ****ed by its build quality and Drop's awful support, so I'm hoping for the Liquid Platinum to be step up on both.
