Turntable isolation platform Recommendations?

I am interested in the HRS R3X

Both the Critical Mass and the HRS platforms are excellent. I just ordered an HRS platform for my Clearaudio Performance DC. I've used CM platforms in the past but my dealer carries HRS so that's what I went with. Also I plan to upgrade my table to an AMG Giro and they recommend HRS. Good Luck!

I do not have experience with Critical Mass, but can attest that HRS has an excellent customer service, should you need to modify your platform down the road. I had to get low frequency absorbing feet when I changed furntables and they were super responsive in making sure that I got the right product. 

The critical mass is the best Isola platform out there we tested both hrs and stillpoints critical mass was Far better

Does the Clearaudio Ovation contain its own integral suspension system, of any kind?
