We had a suspended thorens 166. Tried a DIY high-mass stand. And just like some of the other responses any time someone tip-toed around the living room or even shut the front door the stylus would skip. It was pretty bad until we got the wall shelf. But even with the wall mount you could stll hear outside rumble (traffic, passing trains, airplanes) through the table. You have to be careful where you put the table.
If you have a crawl space under the house, you might be able to prop-up or otherwise support the floor just below the turntable stand to help damp the footfalls somewhat. Rather than let that area be super springy.
