I think I mentioned it before but it's worth mentioning again in all of the Ultra 5 euphoria on this site, I placed 4 Ultra 5s under my SME 30/12 and it turned the sound to mud. It took all of 2 minutes to pull them out. Up to this point I don't use any isolation for my SME but will be trying HRS platforms soon. And just for reference sake, I currently have Ultra 5s under every other box that makes up my front end. A total of 20 are being used but they're not magic for everything.
Frank, Is you SME 30/12 on the steel ball bearings under the four feet or are the rubber inserts still in place? I have mine on the ball bearings. I have not compared, but was told that the rubber inserts are really only there to protect a nice wooden tabletop and that the turntable is designed to be supported by the ball bearings for best performance. I think they drain energy away from the table more effectively.
Much of the SME design is about how to deal with energy. I think internally generated energy moves down through the feet and structural born energy from below needs to be handled by something like a Vibraplane, or other isolation platform. Please report back on your findings with the HRS platform.
I will look for the recent Tbg post about the StillPoints.
EDIT:
It is in the current EMT table thread:

Tbg, That is interesting that you replaced the Halcyonics with the StillPoints. Before doing so, did you try the StillPoints between the turntable and the Halcyonics? Could you please describe how the sound changed?
I met the designer of the StillPoints last weekend at the NYC Audio Show. He indeed explained to my friend and me that the SP are designed to drain internal vibrations down from the component as well as isolate it from structural born vibrations coming from below the component. He also explained to us that his products make the most difference when placed under speakers, then electronics and finally under source components like turntables.
Have you tried placing some StillPoints on the plinth of your turntable, assuming there is room?

Peterayer, I had two Halcyonics unit with one under the turntable and one under the amp most of the time. I had thought to buy more Halcyonics but the price got outrageous. Really it was the StillPoints Rack that came along first. When I put everything on the SP Rack it was better than my previous sound. I longed for the possibility to have all Halcyonics but could not afford that. Ultimately the guy who bought my Shindo turntable wanted the Halcyonic unit so I sold both. The second Halcyonic went shortly thereafter.
I did try various feet between the Halcyonic and the Shindo but they did little.
I think Paul is wrong about where the greatest benefits of the SP Ultra SSs or Ultra Fives are. On my amps SP Ultra Five on SP Component stands are just outstanding. Once I got rid of the acrylic shelves on the SP Rack, the Ultra SSs and Ultra Minis are also outstanding. The SP Ultra Fives are outstanding under speakers, but four are needed, not just three. In all cases four are better than three, but you have to keep all four in contact with the component.
Most vertical vibration is turned into horizontal vibration which can nowhere and thus is converted into heat.
No my present turntable is a Bergmann Sindre with no real suspension. It is on SP Ultra Fives which are also mounted on a SP Component stand. Initially, I am just going to put the Nantais Lenco Reference where the Bergman is now. The hundred pound weight of the Reference will mean something other than the Mana Stands glass shelf.
