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

I use the original Stillpoints with Risers and inverted cups beneath my Teres 320 (85-90lb, unsprung) turntable. They provide a significant lowering of the sound floor vs. the supplied spikes, at the cost of a *slight* diminution of macro-dynamic punch and bass slam. As with most things in audio, it's a tradeoff, but they're a net gain for *this* table in *my* system to *my* ears. Would they do the same beneath another table, in another system or to another's ears? YMMV.

P.S. Agree with Slaw regarding rubber(ish) materials beneath a TT, or anywhere near one. I've tried Sorbothane, Vibrapods and similar in various places beneath my TTs and around my tonearms. The results were decidedly negative: no sonic benefit but loads of added mud. I suppose YMMV, but having heard no audible benefit and serious sonic detriments in several setups, I believe the odds are against it.
