Hi Mark (stiltskin),
My system also sets on 2 Canadian Rock Maple stands! And I have been using a 4" thick Mapleshade platform with tennis balls under it for may amp (which sets on the floor), but I recently pulled out the Rock Maple amp stand that came with my racks. It is coupled to the floor by heavy brass pointed cones. The sound of the amp is much better with this setup than it was with the 4"mapleshade. The SRA iso base is still best under the Berning amp.
