Turntable Platforms - Low mass? High mass? Why?


Hi. I'm a little confused about theory behind what to place your turntable on. I currently have a Rega P25 sitting on a spiked Ikea Lack table. (very low mass)

Would any/all turntables work well on this stand? a Teres? Michell? Nottingham? Or would these prefer high-mass platforms? If so - why?

Thanks!

The Rega philosophy is a light and rigid shelf or platform.Following this I had square piece of acrylic cut to size.Under the turntable you could have vibrapods under each foot.With a Rega P25 you have a 5 vibrapod at the back,a 2 at the next heaviest spot on the left and finally a normal vibrapod on the right where there is not too much weight.This sits on top of the acrylic shelf about 3/4 inch thick cut to size.You put some form of metal spiked feet under the shelf the same as those for speakers is o.k.The vibrapods were worked out after long testing and I can vouch it is effective on a Rega P2 although the original idea was worked out with a P25 and mentioned in the vinyl asylum and Stereophile.
It cleans up the low-end quite noticeably and enhances detail.The vibrapods help the Rega feet drain away vibration as they are supposed to and the rigidity and decoupling effect of the shelf aids this also.
Bright Star Audio believes you should have a high mass (Big Rock 19) isolated with air Air Mass 19. Lots of mass isolated from enternal vibation. Problem is this stuff ain't cheap.
Dear Todd: Take a look at: www.vsengr.com/triorbs.html

These Van Slyke isolators do magic under your TT. I use it after try anything else. It really works.

Regards and enjoy the music.
