Which would you choose to isolate your turntable?

Since starting this thread I have had the opportunity to try a Halcyonics Miro 40 in my system. I have started with it under my Universal player just because it was a lot easier to set it up there. Results are superb. Best bass I've ever had. Excellent clarity. A real eye opening experience. All changes to the sound are positive.

Thanks for all the responses. It sounds like both MinusK and Critical Mass have been compared to Vibraplane and both bettered it. It doesn't sound like anyone has directly compared MinusK to Critical Mass. I know that Critical Mass has three models and I don't recall where the Master Reference falls in that lineup without going back to the website for a check. I remember that the top of the line Critical Mass was more expensive than the $1800 MinusK. I didn't like hearing that the MinusK bounced all over the place and that the chassis rang. Anyone else have anything to share?

I have ordered two Grand Master supports from Critical Mass. I am told it will take 10 to 12 weeks to build them. Don't know if this is typical for every order or if other orders ahead of me are causing a delay. I have been searching for more info on this product but there isn't a lot available yet. I've read everything on their website.

I noticed that Michael Fremer checked out one of the Halcyonics platforms. There doesn't seem to be any flexibility in the Halcyonics line in terms of physical configuration and the prices are outside my budget. I do wish Fremer hadn't been so snitty about the software. It would have been nice to know more about this feature.

The Halcyonics are the only ACTIVE isolation supports of which I am aware.

Whart,
You asked about HRS. I'm not familiar with this. Can you provide more info, a website, anything?
