Granite under wood for better isolation?

Suspended tables will highly benefit from this application.

Reason is for the mere fact the suspended table truly has no plinth and get great support seating on rock solid hard platforms especially when suspended underneath the table with some cones.

Non-suspended tables on the other hand would not benefit from such a application and I would recommend a MDF board platform 2" in height box with a inserted cavity bladder such as a bicycle inner tube or fill the box with play sand sealed.

Again many company have manufactured same design application isolation platforms as mentioned for our hobby and have made tremendous amount of dollars marketing and then profiting big time on the finished products.

Wood colors the sound Granit rings try SYPMPOSIUM IS THE BEST!!

If you take a piece of granite (typically 18"x24" for a TT and at least 3/4" thick) and place it on a bed of sand (typically 3"-4" deep), and add a TT, the combination will way upwards of 30-50 lbs. I guarantee that tapping the granite with a hard object will produce no discernable ring. In fact in my case, such tapping is inaudible through the speakers on quiet passages. I suspect the same it true for bonding the granite with MDF. Try it.

Audiogalore, in what order Granite on top, then cork, rubber, and MDF?

Yes, exactly correct Granite on top then cork, rubber and MDF on bottom.

adding Vibrapod with cones underneath the MDF in a triangle would farther benefit.
