If you have springy hardwood floors, you need a suspension, like a good Sota. I don't think high mass without suspension corrects that problem, but might have other benefits.
I have eliminated the need for a suspension by recording reel to reel in the basement on a concrete floor; you could jump up and down next to the turntable with no effect; I have a lightweight Rega.
I think high mass costs more as opposed to a Rega; while delivering the same comparable sound. Of course one would have to audition the two in order to discern the benefits of high mass, but high mass, or low mass without suspension will not protect from foot falls.
