Maple platforms

Hi

I was wondering if anyone has used maple platforms under their turntable and if so what were the results. An exmple of the platforms I'm refering to can be seen at: http://www.mapleshaderecords.com/tweaks/platforms.php

My rack is MDF so I'm wondering if puting something harder between it and the turntable will improve sound. In other words, does the mdf have a damping affect on the turntable--in this case a Rega 3?

Thanks
