Any suggestions for isolation platform feet?

@George Blair, are you using the cork over the same-sized blue E.V.A. type shown further below in you link? I ask because the E.V.A. type is advertised as "outperforming cork and rubber by 3:1..."

 

No, hadn't even noticed those. I'm using the cork ones at top of the page.

 

Looks like it might be time for a shoot-out comparison!

 

It is my understanding that a good isolation platform will absorb energy. Granite definitely won't do that. I use a Symposium platform under my TT. It is black and looks great and works great. I recommend a Symposium Segue platform under your TT.

 

If you have an IKEA in your area, try the thickest bamboo cutting board. It is a very inexpensive experiment. Like you said, if you like the sound, you can paint (stain) it. If you don’t you have a splendid cutting board for your kitchen or as a gift. You really cannot go wrong with the experiment, but only you can tell us what works best.

 

I use a 5 inch thick piece of granite under my TT and it does wonders to help with isolation. I have high mass TT on top of it. Its a lot of mass therefore takes a lot of energy to move it.

 

I did find this - pretty reasonable if it works ISOLATION PLATFORM - Absorbs Up To 94% of Vibrations | eBay

 

Yes, this will work better than granite.

 

turns out it's too small! The feet on my VPI are over 17 inches apart. seems to be an issue with most of the platforms - they're made for smaller units. crap...

 

Symposium will make a platform to your specs, though I'm pretty sure the stock seque comes in the size you need.

those are nice but really trying to keep the price way down. thanks though. budget is around $150 or so max.

 

I use the blue ones, never tried the cork.

 

overpriced, but it does exactly what I needed it too. Think there's a few similar models, ranging in size, price.

Your granite slab, with four of the feet that have been mentioned earlier in the thread, will absorb all sorts of energy. Granite is used as a heat storage medium for some applications, among many other things. Resonance that reaches a dense substance like granite is converted mostly into a very small amount of heat. That’s one of the important design goals of good anti-vibration/anti-resonance platforms. Thick granite stores that tiny amount of heat quite well, but doesn’t resonate easily. That also means a thick slab of granite won’t ring or vibrate enough to create sound of its own. Granite is also so dense that it offers significant weight per any given volume, which means it tends to damp the vibration of any shelf, table, stand or piece of furniture on which it’s placed.

 

That's a good idea for many tables, but if his VPI is similar to my Clearaudio, the weight isn't distributed evenly across the table because of the heavy motor pod on one side, and the foam will compress more on that side over time unless you use a stiffer foam that isn't nearly as effective for isolation in the lower frequency range we generally want to cover.

For my Clearaudio Avantgarde, I went with two tempered glass cutting boards with a constrained layer of silicone rubber (mold making compound) in-between. Just one of many approaches, but it all depends on what you are trying to accomplish. My motor pod is separate from the plinth, so makes the connection through the damped glass beneath (and the belt). The glass platform is coupled to the rack below with simple thick felt pads, but will be moved to a wall rack at some point.

 

I went throough trying all sorts of support stuff some years ago. You know what I ended up with ? Cork.
If you are really tight (like me...) wine bottle or prosecco / champagne corks work just great. I still use the latter under my valve power amp. I do like inexpensive stuff that works!

 

Some people also use the natural rubber or silicone bottle stoppers available at scientific supply stores in various sizes and hardness levels, they aren't too expensive

 

I'm using a Segue ISO under my Classic 2 SE in conjunction with the Symposium footer inserts. They made a huge difference together. It took a minute to get used to the difference in bass - low end is so much cleaner and palpable. I also noticed more space not just between the instruments, but the individual notes in some cases. Detail and transients are much clearer.

 

I've been using this Block https://www.amazon.com/Maple-Edge-G...?srs=5386164011&ie=UTF8&qid=1519067793&sr=8-8
Supported by these MP-3C - DiversiTech MP-3C - Rubber/Cork Anti-Vibration Pad, 3" x 3" x 7/8"
Under my VPI Classic for a couple of years now with good results.

 

I'm all for the butcher block thing but again, needs to be black. And I'm pretty sure I'm too lazy to sand and stain it - but I might give it a shot. thanks.

 

I am using the Symposium footers in my Prime. I started with the footers and liked what I heard. I then installed Symposium couplers. Again, I liked the improvements. Next comes the Segue.

I wish I could get the Segue. Spent way too much in January - the VPI Prime Scout and the McIntosh phono preamp set me waaaaay back. And I still don't have an MC cart yet for the VPI, which I know is a necessity! or at least a preference and significant upgrade from the 2M Blue I'm using now.

 

Granite is the Devil's work IMO. Lighter materials always work better;, in my experience

 

I sanded mine, Stained it, and Finished it to match the rest of the wood in my Racks.


You could do the same with paint, but it requires a little effort.

 

Why do you feel the need for an added platform? What does it set on now?
