I found that even rapping the equipment stand hard with my knuckles did not transmit any sound to the speakers.
This is another issue that comes up often that I admit I just don't understand. My table is in my finished basement (concrete floor) and my DIY stand incorporates sandboxes, thick hardwoods, granite shelves and Stillpoints. If I wrap on a leg of the stand with the stylus down I can hear a thump through the speakers. Same thing would happen back when I had a Basis 2500/Vector tonearm.
But I have to ask, "So what? Why would you do that?" I'm not in the habit of doing this while listening to LPs. And I don't know anyone else who does this. So I'm at a loss to understand why the vinyl-phile community seems to bring this up as some sort of test to prove or disprove something.
Now, if you can hear your footsteps through the speakers as you walk around the room then I'd agree there is an issue. ;-)
