Has anyone had experiences good or bad with speaker isolation or isolation in general ?

hi geoffkait
thank you for again providing another great answer with a great solution to try from shun mook , i have just ordered 2 Mpingo discs to place one on my lector cdp and psu7 , i am waiting on the spring type seismic isolation platforms , i have 2 sets of final duramas bearing systems which i can place on each platform under the chassis of the equipment , then the Mpingo discs will be placed on top of cdp and psu7 , i will do this in three stages , springs , bearings then Mpingo discs if anyone is interested i will report back with my results , my speakers are already placed on seismic podiums with great results lets hope the platforms bearings and Mpingo discs can bring even more musical pleasure  

The thing about Mpingo discs is they're *very* directional, top to bottom as well as azimuth. They also are very persnickety as to where they will work. So my advice is keep looking until you find the magic spot(s).

hi geoffkait
have you found one product that seems to work more consistently than any other please for the internal vibrations , i once tried the cardas myrtle blocks under my lector and psu7 and found the sound over damped , i know its all trial and error but i have never tried springs under my equipment only the speakers , i use the final durama ball bearing system which i fill increases speed a little brings out fine details in the music and gives a little leading edge definition, over all sound wise they are an improvement sound wise for not to much money, i was looking at the oyaide dots which apparently have a different type of effect dependent on which side is touching the equipment so again we deal with lots of various products so i guess its pick one that hopefully someone has advised and had good results with , obviously if you turn to a dealer he pushes hes own brand thats why i turned to these forums for some honest advice and real experiences rather than believing whats written on the can sometimes as you said "theirs going to be a little rain sometimes " in the uk shun mook is highly regarded it was once considered snake oil or vodoo funny" times are a changing" sorry last question lol do you find ball bearings are a good product for internal vibrations ? if you have addressed this internal vibration issue could you list maybe 5 products that you have maybe tried or would consider are the best of the bunch please i am hoping the  Mpingo discs work as i have already paid and ordered but i also thought the oyaide dots looked interesting but then again so does everything else when you read the spec and how different products deal with it , i suppose stillpoints is top of the list if they deal with the rollerball bearing effect and the  Mpingo discs type performance if you can add anything else its very appreciated regards john

Hi, mains, I’m pretty sure I answered most of your questions in my last post. Why would you fill the Daruma roller bearing assemblies? The reason I ask is the bearings should not be damped, otherwise they won’t be free to move easily. Isolation can be defined as the freedom to move in the direction of interest without constraint, or without much contraint. That’s why the bearings and the cups are tempered steel or tungsten or some other very hard super-smooth metal - To reduce friction and allow the bearings to move very easily when the bearing assembly/component is acted on by external forces. Internal on board forces may or may not be sufficient to cause the bearings to move. People try to damp springs, too. Big mistake. There are many ways and locations to apply damping, which I mentioned recently. Was it yesterday?

hi Geoff Kait
sorry its my bad literature when i said fill i did not mean fill as in to top up , i meant to say felt , just to add more fun to the situation , my seismic platforms arrived  , i placed a granite slab 400/500/30mm on the carpet , then the seismic platform size 1 spring A on top with a single component then placed on the platform and the results was another step in the same direction of the podiums much more music , i then used my clearlight audio RDC 1.2 cones and basses between the platform and the chassis of the component and the sound improved even more dynamics focus clarity imaging sound stage basically everything audiophiles are looking for improved , i must say the seismic isolation products for me was the biggest upgrade my system has ever experienced but how strange the RDC cones and basses improved another element of the sound , the seismic products especially the podiums are the clear winners and should be for the money, but the RDC cones and bases performed even better with the seismic platforms contributing to an incredible listening experience. I replaced the RDC cones and bases for the final durama but i found the combination with the springs to detailed with what i heard as a slight distortion to the higher frequencies but very nice bass how crazy is that , taking the duramas out i have settled on the seismic isolation platform with 3 RDC 1.2 cones with bases but the duramas still did something to the bass that was quite extraordinary but they let there selves down every where else , maybe i may replace the RDC cones with stillpoints and see where that goes on there, i tried stillpoints before and found the performance was not for me , it just goes to prove one size does not fit all , experimenting various ideas on there own and combined can give great results this lovely audiophile life is fascinating and never ending , i strongly believe isolation is a huge area that needs addressing , i found starting with my speakers on the spring type idea worked for me , the springs were then very good under the equipment but then going back to some older ideas i had put aside as being not good enough actually worked much better with the springs but the cheap ball bearing idea actually took the springs into a backward step but a forward step in the bass, so maybe a better bearing  product like stillpoints with the springs will be audio heaven, for now im really enjoying the springs and RDC products under my electronics but by miles the springs on there own under the speakers or maybe i could try the RDC cones or stillpoints as well there who knows that combination could be complete audio heaven , please do not think for one minute the seismic isolation products did not do the job to an amazing level with which one would be 100% satisfied with the results, but slightly tweaking with other ideas as well proved even more beneficial adding different flavors that seemed more tasty when mixed with springs its all getting really fascinating because my system is playing like it never has done before by a huge margin good luck with your journey ignore isolation and you will never really get there i didn't in 35 years of trying
