How to isolate turntable from footstep shake or vibration

D.J.’s from the past were used ash trays with rubber bands wrapped around them. Not insinuating that you are a DJ or a smoker but surely you get the idea. 

Pleased that you got the problem sorted...

SOLID TECH FEET OF SILENCE is a proven solution...their RACK OF SILENCE with the isolation system with TT shelf not only will work for your TT but for your front end equipment as well...Preamp...DAC...etc.

As a general rule, I look for the simplest solution as it is also usually the least expensive.

As many others have noted here, set the table on a platform that’s bolted to the wall. It’s worked for me each time, both in my NYC loft (where I held many dance parties with up to 100 pairs of feet pounding the floor) and in my new home in Newburgh NY. before: vibration bad enough to sound like the woofer was going to rocket out of the cabinet. After: completely gone.

I apologize for being too harsh, Mijo. Was trying for humor. By the way, my OTL Atma-sphere amps originally used the high current Russian triodes (6C33C) designed for use in their jet fighters on board radar. This was deemed advisable because tubes are immune to nuclear blast emissions whereas SS is not. The US countered with an even higher current triode, the 7241, which until not so long ago was used in our own radar installations, at Andrew’s Air Force Base in MD, for one example. It may still be in use, for all I know. Anyway a few years ago I converted my amplifiers from the 6C 33C to the 7241. They are way more expensive and harder to find, but the sonic benefits seem worth the effort and expense.
