Let me rephrase the question. How important is vibration control? I would answer that it is one of the most important things you can do for your sound.
I am one who started my audio experiencing with my equipment on 1 x 6" planks using cinder blocks between them. I incrementally had improvements culminating with my trying the StillPoints Rack. It was outstanding. I had had Mana shelves before with two Halcyonics Micro active isolation devices. With everything on the StillPoints Rack, my sound was much improved
Later I tried the StillPoints Ultra SSs. Even on the StillPoints Rack, there was great improvement, suggesting that most other isolation devices are on the wrong track.
