vibration isolation bearings


Not really sure where to post this but I need it for some amp stands.

There is a vender out there that has 2 concave cups that hold a bearing in between, they make them for components and also build them into amp stands. Trying to locate the company to buy some does anyone have a link?

Or I do welcome any other inexpensive ideas to support two platforms together and add dampening.

FIM is the company you are thinking of.
Stillpoint makes a dual cup with a bearing also.
Aurios Pro Max's are another product with 3 captive bearings internally.
google "fim isolation"
GalenCarol audio is really helpful and has a chart describing the effects of different isolation products

any will work, just looking for the lowest priced ones. I need to make several stands and it is getting expensive. I think the FIM was what I was looking at but to much $$$ the symposium also look nice I am trying to get a price on them. The stands will be spiked anyhow and weigh about 40 lbs so this isjust to make it a bit cooler and may add another layer of isolation but not 100% necessary.
