Isolation feet for monitors


I need to isolate my Linn Katan monitors from the bookshelves that they currently sitting on.
System can be viewed here : http://forum.audiogon.com/cgi-bin/fr.pl?vopin&1095824323&view
I have placed a 12”x12” slab of granite between the speakers and the shelves for mass, but now need some sort of isolation footing to separate the speaker from the granite.
A cheap solution would be to insert some neoprene pads beneath the monitors. Has anyone tried this?
Another option would be isolation feet or spikes. Are there any cost effective suggestions for feet?
Thanks

The isolation is to stop the speakers and book shelves resonating together - the shelves are very light and thin so i sometimes hear a tze, tze at high volumnes. So perhaps weather stripping between the speakers and granite bases will help to bind the speakers to a massive base and then some neoprene between the granite and shelves will help to stop the shelves resonating at higher volumnes. I will give it a try
