How to isolate turntable from footstep shake or vibration


Even while the Oracle turnable that I use has a built-in springs suspension by design there is a low or even sub-low frequency boom every time someone walks in a room. This becomes really bad with the subwoofer’s volume set high as the low frequency footsteps make straight to subwoofer where they are amplified shaking everything around. It seems the cartridge is picking up the footsteps very efficiently as even a lightest foot down becomes audioable. What can be done to attempt to isolate the turntable from the low frequency vibrations? Interesting, that the lower the volume of the subwoofer, the less the footstep shake is evident and with the subwoofer turned off it is a barely a problem at all.

Jordan Peterson sold me on the idea anything worth doing is worth doing poorly. His point being too many people put off doing until they can figure out how to do it perfectly. In that case it is better to do it poorly, because then at least you learn from experience and maybe make it better next time. If you improve something even if only by a little bit, but keep at it, eventually it will be quite good. Or in any case a helluva lot better than when you started!

Perfectionism is procrastination and absolutely nothing else.
I think it is a bit dependent. One usually prizes perfectionism in a brain surgeon but not in a good manager. I am very pragmatic and can vary my precision based on the task at hand. I my way to the executive level in Corporate IT, so had to deal with many perfectionist programmers that would never finish anything.  My best friend is a perfectionist and has spent his life struggling to keep his head above water. He tried to be a Doctor, but just didn’t quite make it. Growing up with him I always felt inferior, I now look back and feel very sad for him… it can be like a disease.
If you are in audio, and especially if you are into improvement, then it pays big time to be willing to try stuff out without being overly concerned how perfect it is, how it looks, etc. 

People ask me this one all the time. What is the best one to do? What is the most important component? What is the weakest link? These are all based on a false premise. Every link is weak, at least in the sense it can always be made stronger. Every component is the most important.  

Before I came to this realization I was building shelves out of different materials, sanding and finishing, doing all this work that only makes it look good but has nothing to do with how it sounds. Eventually I figured out I can cut a piece of wood, stick it under something, and hear how that wood sounds without going to all that trouble. 

The perfect example of this is the tone arm board. This can be anything. Could be cardboard cut with scissors. For sure could be MDF, or any piece of wood, acrylic, plastic, aluminum, Corian, whatever. Don't even have to drill holes, because for testing purposes you could stick the arm on there with tape or blu-tack or heck some arms even gravity will do.  

Nobody ever does this. If they did they could learn a heap in no time flat. But they don't. Why? Who knows. Appearances. Everyone so freaking worried about how it might look. 

Me, I am concerned with how it will sound. What did Magenta say again? "Risk it!"
