Doubt that it is for PD's only - I had one of those hubs a while back. I agree that most conventional cassettes sounds like an amplified recording of a squurill biting into a nut...
However, I can't entirely agree that most freewheels are silent either. Closest I've gotten to that was a gummed-up (with both grease and cat hair, yech) Sachs which retained its "stealth" sound after flushing it. Every single Regina I've tried sounds as if there is a woodpecker on my rear hub. Shimano's UG freewheels are slightly better, but not by much.
What type of freewheel is the O/P running?
Take care,
