Are vibration damping tweaks worth the money?

Thousands of dollars are spent without hesitation on vibration damping materials, bases, and feet for high-end audio. Is it worth it? Can we hear the difference? And how do you rank their importance in the grand scheme? I am getting close to publishing my memoir! It's called 99% True and it is chock full of adventures, debauchery, struggles, heartwarming stories, triumphs and failures, great belly laughs, and a peek inside the high-end audio industry you've never known before. I plan a few surprises for early adopters, so go to https://www.paulmcgowan.com and add your name to the list of interested readers. There's an entire gallery of never before seen photos too.
