I own a Dynavector 17D3. I think that D series all have one-piece diamond cantilever/styli. So if and when the stylus wears out, you would have to replace both if you want to preserve originality. Am I correct in this belief? (Raul?) If so, does Dynavector have the capability? I rank that cartridge as upper level but not tops. Very enjoyable, nevertheless.
Under a microscope, it does appear that stylus and cantilever are one piece.
