to me the main difference in sound is in the tenors. maybe that's because i'm a tenor player, but put a set of pearls and a set of dynasties in front of me with the same heads, same tuning pitches, and i can pick out which is which every single time.
people always say dynasty snares sound like tabletops, but that's because that's the way bd tunes their snares, and bd is dynsasy's posterchild. the reading buccaneers have been using dynasty percussion since 05, and they get a really nice snare sound. very different than bd. their quads, however, still sound the same.
