One of my cats regularly jumps onto my SOTA Sapphire, for one because it gives the best cat-centric view in my stereo room. Because I always run the TT with the cover closed it's no problem. Other than a revolution or two of eight track tape style wow and a paranoid moment from yours truly, nothing happens. I remember going to a hi-fi show way back when where the SOTA guy lifted a SOTA up off the equipment table and swung it around while a record was playing to prove how excellent the device's isolation was.
