Nick, I tried the middle of the floor also, but it didn't help much. My basement has been partitioned off into three separate rooms. The interior walls and the ground floor support columns are distributed in such a way that I don't have a spot that is very far from something that connects to the floor above. One of the many things that continues to supprise me is how small a move from one location to another can result in a significant difference. There is probably a really quiet "node" somewhere, but it would take a long time to find out. One of the other things I've learned is that if I move the thing, it can take several days to stabalize, during which time I typically see occasional big transients and I have to tweak the leveling at least once a day for a week or more before things settle down.
