They're not Constantinople's but still perhaps at least from the concert player's point of view, these can be considered as desrable rarities.
As for the sound file that he offers here using Beethoven's "Ode to Joy" as the vehicle for his demo, I feel that this doesn't really tell me anything about how these cymbals actually sound. I say this because the cymbals are virtually buried beneath the orchestra. So even though I know precisely where the cymbal crashes are from my prior familiarity with this piece, as far as this specific example is concerned, I can't hear SQUAT in there.
