Vibrapods beneath my CDP sucked the life out of the music. Sorbogel footers beneath my Harmon Kardon/Rabco ST-8/ADC XLMII did the same. I'm 100% behind TheAudioTweak on this one: keep these things away from any component whose parts are designed to move or vibrate. (He would say that means *all* components, and I wouldn't necessarily disagree.)
The only benefit beneath my TT was protection from heavy-footed pedestrians. The cost was a serious degradation of HF transients and clarity, sort of like having VTA set too low. The solution is obvious, ban heavy-footed pedestrians AND dampening devices from the vicinity of your TT.
P.S. It's possible a suspended TT like a Linn *might* react differently, since the platter/arm/cartridge would be more isolated from a deadened plinth. If your Technics is a direct drive, this (untested by me) theory wouldn't apply. My guess is you'll do better without them. Why not try and let us know?
