Stillpoints under a turntable?

Sprung chaises will do fine. An unsprung table might do best with some kind of rubber based material.

Schipo: I have to strongly disagree. Any kind of rubber based material 'anywhere' in the component chain is a no-no.
It traps/stores energy, does not dissipate.

Hi, I use ULTRAs under a Kenwood KD500 (extensively modified and upgraded from all aspects), as well as on a VPI Super Scoutmaster. Excellent results with both. Everything in that front end better be right, or will hear it- good and bad.
Spent the last 25 years in this business- last 12 years in manufacturing. Also worked closely with the people at Stillpoints.

Good luck and take care,

Dan
