A wall rack is a good idea. A rack on a load bearing wall even better. When I was just out of college I put my Sota table on a granite slab that was pried off the front of a building that was being torn down. The slab was placed in a window ledge with rope suspending/anchoring the front of the slab to the top of the window sash. PARTAY! The cool thing about the Sota tables is that they are reverse sprung - the spring doesn’t compress, it is suspended. Good luck
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.
