Hello Halcro, I'm inclined to accord with ct0517 that
"if you want to keep that white shelf, the Victor/armpods in that TT location you need to add a level on top of that shelf that the Victor and armpods all join to
for isolation. This will then become the common platform aka plinth for that whole turntable system"
The spiked Victor plinth is likely conducting mechanical vibration from earth or some combination of all those vibrating components in a row. The most effective approach will be isolation-based, perhaps similar to the softly sprung platform that I use to elevate all the separate pods of my VPI. In this case the 150 lb. sandbox/plinth assy floats on six soft springs with a resonance of around 2-3 cps. A heavy maple or marble platform could be substituted for the sandbox.

It might first be helpful to check if the vibration occurs with the Victor elevated on a pillow.
