Using Maple Butcher Block Under a Turntable


When using a maple butcher block under a turntable, what is below the butcher block?  Cone?  Soborthane pucks?  Does it just lay on the shelf?  What are people using and how of they mounting the block?  How are they mounting the table on the butcher block?

When buying Butcher Block....make sure it looks like a checkerboard with the grain going in different directions. 
I recently bought a 3" thick bamboo cutting board that I made into the top of turntable stand.  I cannot make a direct comparison because it was for a new turntable, but the system sounds very good.
I'm now using the isoAcoustics Delos, instead of the ButcherBlock Acoustics I had before. It's more expensive, since it has four of their iso-pucks embedded as feet, but I'm happier with it and I'm now able to use my turntable on my equipment racks instead of dedicating a wall shelf for it. 
I use a solid bamboo tray I found in Crate and Barrel or somewhere like that.
