I don't see how that could happen. Isn't the epoxy in the hole that the diamond is attached too. The images I see usually show the epoxy all the way out the top of a cantilever to diamond attachment point. I can not find any images of the ART-9. Only computer generated stock sales literature. But still, epoxy only at the very bottom of a Boron cantilever. Does not sound like a firm attachment.Hello, I realize that this is a very late reply and yet, I hope I'm in time. I used the magic eraser, and it magically removed the epoxy resin that secured the nude diamond in the Audio Tecnica AT-ART9 cantilever. This was the second cartridge on which this happened. I finally figured it out and realized that the abrasive eraser was doing precisely what it was designed to do. Erase.
