Are You Sorbothane Experienced?

I have a sorbothane turntable mat...and I find it works well. I tried the feet a long time ago and can't say it was worth it and made it much harder to set up.

The Sorbothane folk at isolateit! make it explicitly clear that for their material to work effectively simple calculations need be made to order what is needed.  Determine the total weight to be decoupled from whatever it is placed upon-that will tell you how many isolation devices need be used and the durometer rating they should be ordered in.  i have a 44 lb granite slab upon which my 20 lb table sits (64 lbs total) which has 10  1 1/2" diameter x 3/4" tall Sorbothane isolating hemispheres used by me as feet placed between the granite and the stand working in conjunction with each other to provide proper isolation. Each of these 10 feet were ordered with a duro load rating 30, which provides isolation for a load of 4 lbs to 7 pounds each.  Thus 64 lbs divided by 7 pounds each thus needed 10 of them.  Yes they are compressed when in position bearing that load, but function perfectly.  No wonder they did not work out well in some of the applications described.  Duro ratings of higher than 30 support additional weight each so the determination can be made to get the proper fitment for the load to be isolated.  Have photos of my application of these but am a newbie here on AudiogoN and don't know how to get them posted here. Sorry, hope this extended information gives some needed guidance.

Audio quest made some squishy S' feet ages ago

--thank heaven they disappeared--meh!

The really only decent use/misuse of the dreaded Sorbothane was the

Mission Isoplat---if you can find them--they are worth trying

if you want to completely isolate your TT from its surroundings down to at least 4hz i would check out a Townshend audio seismic isolation platform they, come in various sizes and can be built for the exact weight of the equipment it would be supporting and can be leveled once the TT has been successfully placed on top of it. if the platform is out of your budget take a look at the Townshend audio seismic pods you can use 3 or 4 and they are also adjustable so leveling your TT is very easy , theres been some great reviews in the uk regarding the seismic isolation products , the seismic podiums are platforms designed for you speakers to be placed on the results are absolutely incredible .  

sorry my experiences with Sorbothane have always been negative , even when i tried the clearlight audio RDC 4 cones with the sorbothane layer i found it kills the dynamics of the music , but if you wish to try it look out for a set of clearlight audio RDC 4 cones I prefer the RDC 1.2 cones with bases around 50gbp for a set of 4 no sorbothane in them or theres a German company called BFLY they build platforms using different layers of various materials and sorbothane is one of them , the do a 3 platform range i think which can all be leveled and they also sell isolation feet using the multi layer various material idea , i have tried the probase two around 500gbp i found the results a mixed bag so i didnt buy but your situation may be different good luck
