The Credo video is indeed a bit cheeky, a former distributor claiming to have taken Max‘s work to another level.......Interesting guy (Ozzie) with a background in microwave engineering. I had an enlightening conversation with him decades ago about vibration and damping (in connection with turntables) and he seemed to have all the fundamental principles pretty well nailed down even then. I ended up buying one of his turntables, which I still own today.

@sokogear - If you want a taste of the Townshend isolation products without the cost, take a look at my system page, which shows pictures of individual springs that are damped using very thin-wall heat shrink (somewhat loosely applied) with one or two small holes to allow air to escape. Other benefits of the heat shrink damping is that it creates a better bond with the bottom of your speakers or speaker stands and it protects the bottoms from being scratched by the bare springs.
One source I liked using is Century Springs, which have an easy to use spring finder feature where you input the spring parameters you are looking for and are provided with a list of springs meeting your parameters. I have teed up the search feature for you in the provided link. Expect to pay about $6-$20 per spring.
Otherwise, try Nobsound.
that are damped using very thin-wall heat shrink (somewhat loosely applied) with one or two small holes to allow air to escape.Rather elegant minimalist approach, I assume only shrunk at the extremes to preserve its more ’squishy‘ state and prevent friction. I guess another option would be to use an even more flexible (possibly corrugated) hose material and hose clamps..
@mitch2 - as I previously mentioned, I use the Townshend seismic platform (with 4 podiums underneath) for my turntable. It was like listening to a new turntable when I put them in, after I got the correct podiums for the small weight of my table. Every adjustment was noticeable along the way when I was trying a little more weight under my turntable, etc.
I am also going to check back with Symposium Acoustics. They have a great solution also, but couldn't accommodate the small weight of my turntable without having to mess with counterweights that would have had to go on my plinth, which for my table (Rega P8) wouldn't have worked. I'm thinking of putting their version of a podium under each one of my discs to get even more isolation. I'll let you know if I do anything with him or Townshend. I think I can get the Townshend platforms for less than $2500 based on my speakers' weight.
@sokogear - I forgot reading about how much you like the Townshend platform under your turntable, so you are indeed familiar with the benefits of their products and the principle. Since it seemed from your posts that cost may be an issue (relative to the price of your speakers/system) I shared what works for me at a fraction of the cost.
Some of this audio stuff seems like a Zeno's paradox where each step is half the distance to the wall. At what point are you at the wall, even though you never will be, and what is each subsequent half step worth?
