Yeah, like dill said Herbie's should be your first stop, Tenderfeet, Baby Booties depending on the weight distribution they really do a great job and are fairly priced.

Mass on spring. You know, real isolation. Like say Bungee cords.

Vibration control: isolation vs transference.  Different techniques yield different results.  Much depends on how resolving your system is.  For my amp, I use Symposium Rollerblocks upside down on a Symposium Svelte shelf.  For my laptop and streamer, I use the Mini-Stillpoints on a Symposium Svelte shelf.  Symposium’s Fat Padz or Point Pods are less expensive and work well.  IME, rubber feet muddies dynamics - even with a laptop.
