How effective is the Vibraplane & what's the price?

Anybody use Minus K Technology or Herzan? 

Use 3 stillpoint ultra 6’s under the table which rest on a 3 inch slab of walnut.

I use a Minus K and love it under my Brinkmann Oasis. I used to have a second one under a Clearaudio. You have to weight them to their limit, though, to get best results, and balancing your TT on them can be a little challenging. I use heavy brass discs to distribute the weight. Also, they seem to work better if you put a shelf or platform on top of the top plate--I use a Adona multi-element shelf.

I think a new Vibraplane is $2,000 to $2,500. It is very effective. You should call Sounds of Silence. Steve Klein is a good guy to deal with. I also looked at minus K, but per the note above from wrm57 I decided I did not want to deal with the balancing. The Vibraplane is easy to use and I check the leveling about once a month. It takes about 5 minutes. There is a guy on What's Best Forum that uses a Herzan. They are expensive.
