I had a serious vibration and acoustical problem, because my TT platform rested on a suspended floor (i.e.-not concrete, but joists) I tried mounting a platform on the wall, but still had problems. I finally suspended my table platform out from the wall using heavy duty springs in 4 places. The platform doesn't touch the wall or floor and the cables that do touch the floor and wall are isolated by springs. The platform is bubble level, yet it is suspended. I have a friend who hung his platform from the ceiling accomplishing the same end.
People who have slab floors are fortunate indeed. Ya have to work with what ya have.
