I read your eloquent post. And I guess I am confused. I am not the brightest person so forgive me.
You seem to be taking a negative view on isolation and absorption merchandise sold by audio enthusiasts. And then in your final section you say that vibration management tools makes sense as part of the sound reproduction process.
Can you please clarify what you’re saying and provide examples of how someone would improvement to eliminate vibrations that are detrimental too good sound reproduction, which I’m sure exist somewhere.
Maybe another way to look at this, is to find ways to better manage sound dispersion throughout the room as well as minimizing vibrations that interfere with component performance, which is a more abstract concept I think. It is really easy to understand why you’d want to minimize external vibrations from a record Player as Jumping rope next to a record player likely interferes with a record being played, adding cushioning on the feet of a record player to prevent this seems like a good idea. Further, my subwoofer cabinet directly vibrates my floor which causes vibration noise from things on my shelf, an aluminum window frame, loose knickknacks, but if I put a squishy isolator disc thing between the feet of the subwoofer and the wooden floor it tends to absorb the sub cabinet vibrations and improve dispersion of pressure amplitudes more evenly throughout the room which is ideal for a sub.
Thank you
