Isolating components from vibrations is an audio fetish IMHO that is exploited by charlatans marketing to the worst of the nervosa syndrome.
Each object has a resonant frequency, and it’s going to resonate in the presence of that frequency, and there’s nothing you can do about it. You can change the resonant frequency, such as by putting sand or lead shot in a speaker stand, putting a bag of sand on top of a component, etc.
>>>>Actually, there is something you can do about. That’s the whole point! Let’s take a straightforward example, shall we? Tonearms and cartridges are designed to have resonant frequencies circa 10-12 Hz. The reason for that is so acoustic waves won’t excite those resonant frequencies, as they well below the acoustic output of most speakers. But guess what? The range of Seismic frequencies which is 0 to 100 Hz includes the Fr 10-12 Hz so can obviously excite those resonant frequencies. You agree that’s not a good thing, right? So, isn’t it logical to conclude that isolating the turntable from seismic frequencies will reduce vibration of the tonearm and cartridge. No one ever said isolation is perfect but it’s a lot better than nothing.
