There are some discussions over at AudioAsylum about Dynavectors with off center cantilevers. I had a similar problem with a DV20XH (the model just before the one you have). The dealer refered me to the distributor who exchanged it for another. So, be polite and it should work out for you.
PS: Disappointing to hear that new Dynavectors are still shipping with off center or slanted cantilevers. The good news is that the distributor is a good guy and very helpful.
