Review on 🔊 Nobsound Set of 4 Anti-Vibration Amplifier Feet Speaker Isolation Stand Pads for CD Players by Micky Lovett

Any combination of springs and mass resonates at a specific frequency. The spring rate for these feet can be reduced by removing the springs, but they resonate with the mass of the platter at a frequency high enough to disrupt record playback. Removing the springs or adding mass to lower that frequency will cause the springs to drop (full compression) until the resonant frequency is adequately reduced. Instead, I use these feet under a PC whose fan sends vibrations to the turntable.
