I think that there can be MAJOR differences with various tweaks such as those that are weight, isolation, coupling, damping, etc... based depending on the type of flooring that one is on. Someone on a hard concrete slab will have VERY different results using the same tweaks as someone with their gear on a suspended floor i.e. over a basement or crawlspace. The results from one suspended floor to another suspended floor will even vary as they may have different levels of support / flexing taking place. Sean
