+1 on wall mounts. My house is 2+3-story all wood framed perched on steep hillside. The upslope side is 2 stories and the downslope side 3 stories. The main listening area is hardwood flooring on the top level of the 3 story side. Playing vinyl was disastrous until I went to a wall shelf, on an exterior wall, with a sand/air platform base. Before the wall mount any footfall, door close or heavy flatulence would cause a skip and/or jump!! It hasn't been totally eliminated, but now it takes a pretty forceful "slam" of the entry door to create any issues.
Cheers,
Geay
