hi Jamie, Do you know the material for the ball at isocapfeet... İ could not find at the description
And what is the total weight upper platform of existing sandwich with turntable together more or less. because with sorbothane not only upper load capacity say here 16 kg. is important. Sorbothane has also a lower load limit. Best works between upper and lower limits.
Please go through this link

hi,
thanks for your reply,my turntable weighs 8.2 kg,the board it sits on weighs approx 1 kg so roughly in the middle of the weight specs for the sorbothane cups.

It's not costing a king's ransom so if it were me I would give it a go. It may be better, worse or do nothing - only one way to find out. :)

Hi Jamie,

I use four of these under a platform made from a laminated dense isolation material, it is very heavy and similar to slate in acoustic properties, but you could use a 3 inch maple wood shelf. I then stand my turntable on the shelf but the VPI Scout has its own ball bearing tipped isolation feet. It works very well Indeed.

Have a look at some of the suggestions the Vibrated company have for building a platform with the sorbathane vibrapods.

Good luck

The isofloat is very good at that price

cant find any info on building a platform though.

I think they suggest to use two shelves with Vibrapods in-between.

or you can use vibropod cones with them

thers no info on line at all regarding this one http://www.ebay.co.uk/itm/2519640375...%3AMEBIDX%3AIT

What strikes me is the lack of objective measurement for these devices. No reviewer bothers to test either decks or supports for degree of isolation. You might ask yourself why.
The result is that all sorts of claims go unverified.....I've used sorbothane in a 'sandwich' but it's no more than vaguely helpful if you have serious isolation issues. To my ears, well isolated decks have a characteristically 'calm' sound, poorly isolated decks often sound coarser. This is then described as 'more alive' or similar.
Objective tests would solve this issue, and make clear where the truth lay, but I am not holding my breath. Too many vested interests.

And how would you propose to do an objective test?
