Dear Nandric,
My DD/TT is a Victor TT-81 made for JVC ( and soon to be replaced by its scarce and finer brother.....the TT-101).
They have their bottom metal 'cage' attached (just as the SP10s have) so that spikes or 'footers' can be positioned under this 'cage'.
I find that placing the spikes under the vertical cage perimeter, results in the greater stability with no movement whatsoever in my particular case.
