Manitunc....sorry to hear about your alarming experience.
One possibility is that given your max VTF, if the VTA is "tail down" the Washi paper could be skimming the warps on the disc(?)
Carts with an "undercarriage" tend to register disc contacts as loud thuds but the Lyra, whose stylus is mounted through the front panel, might instead just hash the high frequencies and sound mis-tracked whenever it touches down? Once friction gets going you might find an accumulation there too?
Just out of curiosity are you loading the cart "fully open" or with a fairly low resistance?
