Sadly, the more snake oil prone audiophiles might think $2,500 to isolate a solid state monoblock is a dealTwo 19 x 16 Vibraplane Active Isolation platforms is your answer. Only $2,500 each (air pump not included), BUT, they really work, really isolate, really kill vibration.
Here are the specs for a Vibraplane, The vibration of homes and buildings is typically up to 60hZ.

I have been looking at the "specs" for the typical audio "isolation" devices and none of them (that I can find) provides any specifications on actual isolation (vibration reduction), what frequency, etc.
Devices that really do require vibration reduction, like high power optical microscopes, precision scales, and SEMs, all use isolation devices that are measured and come with specs.
Professionally, I have mainly used the similar Newport Bench top active isolation systems (https://www.newport.com/f/benchtop-compact-vibration-isolation-platform) you really can't beat an active isolator for vibration sensitive optical instruments. They are really fun to watch work.
PS They actually run for a reasonable time off of a large Nitrogen tank so you can use that to avoid the extra vibration from a pump.
I have been tempted to pop a turntable on an old one just for fun. (i.e how hard can I shake the table), and am really suprised that none of the subjectivists audiophile youtubers have spent less than a "tuned RCA cable" on a couple of these.
Although I am willing to bet that the biggest vibration impact on the average solid state devices will be the volume pot wiggling
