I'm on the road right now using my phone and couldn't make out the accuracy of the stamp description. However I did notice that one of the cymbals had several cracks around the hole. Maybe for others it's not a big deal, but I personally would not touch that cymbal with a ten-foot pole at any price. The other cymbal also seems to have what looks like a crack or potential crack near the hole.
Can you really see well enough from a video to see cracks? I don't know. Personally I have to see each one in person in order to find them. Anyway here's the statement from man himself:
"They are all without defects or cracks, except for the short sequence with the 22" OS IV with the visible damage, greetings Matthias."
