the ceramic, conical shaped pieces did not come with screw in pieces, just flat ends with a hollowed out recess on the flat end.
I was trying to reduce any vibrations coming through the tonearm, although I really did not notice any until I placed the units, as instructed on the bottom of the plinth. The cabinet is a rather heavy oak piece and the floors are heavily carpeted. As I mentioned before, was trying to improve the bass which seems very anemic. Perhaps I should upgrade the platter first?
Thanks for the reply.
