best support shelf/isolation device for a rega p9?


I have a p9 and it is in a softwood (cedar and pine) cabinet. I am looking for suggestions as to what others have tried for support and isolation. I've heard heavy granite may be worse than an ikea honeycomb lack shelf, I've heard aurios may work well on a maple cutting board, I've heard nueance shelves may be excellent. I have heard that sorbothane is not good. As you can see, I have heard ABOUT many things, but have not been able to try them yet. Would love to maximize the potential of the table.
I can't mount it on a wall shelf.
All advice welcome.
Thanks

the ikea lack shelf when wall mounted. Is my idea of an ideal way to listen to this table. I would stay away from the sorbothane for all turntables it has a way of dulling sound.

I own a P9 - great table. I tried a Symposium Ultra and it was awful (with Rollerblock Jrs in between). At loud volumes the table would pick up vibrations from the bass and it translated to a loud distorted hum. I contacted Symposium and they indicated that this might occur. Removed the Ultra and used a Brightstar AirMass with the Jrs in between - perfect!
I have a P-9. At the suggestion of my dealer, I removed the stock Rega feet and use Walker large cones/pucks. These sit on a 1/2 thick slab of solid steel plate with a soundcoated paint. this sits on the top shelf of my Solid Steel 5.4 rack. Rack's bottom points rest in brass receptors. I have had no problems with any kind of resonances/feedback.
I am told that the BEST way to isolate the Rega is to place it on the Rega wall shelf and mount that on the wall.
