Cones under a suspended table?

One of my tables is an AR ES-1, which I've made many upgrades to over the years. It works well, and is relatively free of influence from footfalls, but I'm looking to optimize the coupling between the table and the custom shelf it sits on (I made it from 1-1/2" of HDF, under which is a layer of Sorbothance, and under that a sheet of granite). I've read on the one hand that tables like this work best with their stock feet (little rubber feet), but I'm not sure I believe these can provide the best transfer of unwanted energy from the TT into the shelf.

Anyone have experience in this area? I was thinking of trying Black Diamond cones or something like that in that sort of price range. I've been told Stillpoints are supposed to be "right" for suspended tables, but they're a little too pricey - given the age and relative value of the table. Looking for a cost-effective improvement.

Other things I've considered are Audio Prism Iso-Bearings or a set of spikes (generic) I already have resting in Isoclean Tip-Toe bases. I'll repeat that the TT is pretty well isolated from external vibrations; I'm looking for a way to drain unwanted energy from the table into the platform in the hopes of improving clarity and control.

Good deal Tonyptony. I sort of assume that you did that because the cones, if used with the points down would not give clearance from the original feet. Correct? You may want to try removing the original feet and replacing them with the cones. If you don't already have them, you can get screw post for the cones that will fit the screw holes in the plinth of the table. I would think that that would give you the most improvement. If you get some mk3 cones, try mixing one or two with the mk4 cones. This seems to bring out the best of both for me.

Good listening,

I've used Vibrapod Cones with quite good success on several of my components. If you call the Vibrapod company, you will get good advice on installation and set up.

Compared to other "cone" products, the Vibrapod cones are quite inexpensive.

Mike, yes I was thinking of getting the add on screw posts and giving them a try, but at the same time I'd been thinking of getting a new custom plinth. :-) One thing at a time.

Tonyptony:

This was one of the first tables I was introduced to regarding (high-end), what's better than normally found.

I think it's an easy recommendation... Always replace any rubber feet with a material that resonances can "Pass" through! No brainer!

Then, the issue becomes, how do the (new) feet SEE the platform it's now married to???

This is going to be your major issue going forward, just remember you're choice to get rid of rubber feet was the right one.

Just a thought... I wonder about replacing the AR rubber belt with silk bead cord??? If possible, I think this will be a major upgrade!
