I did the same thing with my Benz onto my VPI HW-19. I dropped the arm short of the platter, then overreacted and jerked the arm up so it bounced off the record.
Damage? Maybe the Benz cantilever is slightly off on the azimuth. I've used a Geodisc to measure things and, when I'm feeling saucy enough, I'll adjust the tonearm a bit to ever-so-slightly to adjust the azimuth.
But I can't be sure the azimuth wasn't off before the drop.
If the records sound the same, then steady on.
