I concur with Stringreen's entire post, including on rubber footers of any kind. At a minimum, bypass them for the support structure of the TT. If feasible, remove them altogether.
Rubber absorbs vibrations and releases them after a time delay. While this process reduces each vibration's frequency and amplitude, the result is always sonic mud.
Of course Stringreen's tongue was in his cheek (along with the sauce, no doubt) but sauce cans would probably act as an echo chamber and do something similar, especially if they were empty. Still, their rigidity would be sonically better than rubber and you could experiment with different flavors. ;-)
Solid blocks of a dense metal would be better. Solid blocks of very dense hardwood would be better still. Best of all are well designed and engineered footers that reduce the frequency of incoming vibrations to below the audible range (e.g., Stillpoints). This lowers a TT's sound floor without introducing sonic mud. They sometimes soften transients and micro-dynamics so it becomes a trade-off, but rubber introduces sonic negatives that can be avoided altogether.
I also had a VTA adjusting sleeve and a suspended c/w on my old Origin Live Silver (Rega clone tonearm). They both made a nice improvement, but eliminating rubber anywhere on a vinyl rig will make a much bigger one.
