High End Isolation - HRS, SRA, Active platforms

I would appreciate any opinions on cost-no-object isolation strategies. I have highlighted several in the title, but would appreciate any others which may be lesser known and underappreciated.

Please state whether you have first-hand experience with the product. Very important if you went from one product to another due to an improvement.

Also, please disclose if you are a dealer, distributor, or representative for a product. I think dealers have valuable information since they are enthusiasts that typically choose products that are most enjoyable.

Thanks
Rob

I have one Halcyonics platform and two Critical Mass Grand Masters. RTNL -- In answer to your question about stacking components on the Halcyonics platform, it depends. The Halcyonics Micro 40 will hold 100 kilograms (about 220 lb), however, you don't want whatever stack you create to be too tall. I am stacking two components with a total height of about 12 to 14 inches and haven't had any problems, but a taller stack (which I have tried) creates sort of a vertical cantilever effect which (particularly if the components are heavy) if bumped, can cause everything to oscillate while the platform tries to regain control of the mass.

In the case I tried, I was attempting to put a lightweight rack on top of the Halcyonics platform and then add components to the rack. It was just too tall.

Having said all that, IMO there is no better isolation platform extant than the Halcyonics.

Any passive design will have a resonant frequency, below which it will not isolate. In fact, around resonance it will amplify the vibration. Although some passive systems are designed to be tuned to the specific weight they will support, many designs are not and hence, their properties will vary with the supported mass.

Therein lies the beauty of active isolation.
