Mijo, Mijo, Mijo. You consistently mistake your own observations and opinions for science and facts. Tubes are microphonic, some more than others, and most tube gear does benefit from isolation and dampening. Not necessarily with spring suspension. Like I said, some guys even isolate, suspend, or dampen their solid-state gear, although the rationale for that is perhaps less obvious. If you ever looked inside a Halcro preamplifier, for one example, you would see that the entire printed circuit board has been sprayed with a rubbery coating to dampen vibration of the individual components. And that is solid state to the utmost.
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.
