How important is an audio rack?

IME, an audio rack is important for anti-vibration (within one's room) purposes. OTOH, gear can be placed onto butcher blocks of wood resting on the floor (like audio shows).

An audio system is a chain, made up of links and it is only strongest, as the weakest link.

TBG, I live near a Still Points dealer. I may try the Still Points Rack.

Thanks

An experienced audio dealer provided me with a custom modded version rack based on the Naim Fraim design .

I was skeptical (at a minimum) before testing it. But after its insertion into a high-end system, I was unexpectedly gobsmacked at the large improvement in sound stage, further clarity (like a veil was lifted); and further elimination of the noise floor.

The testing effect first on the CDP was dramatic as "Stage 1"; and the further improvement effect on the amp was not-subtle as "Stage 2".

The pre-new audio rack kit sat on Mapleshade 4 inch maple bases with Mapleshade brass footers; all on a name brand moderately priced stand.

What floored me was that this "old" set-up was SMOKED by the new audio rack set-up without all the extra MS trappings.

Go figger.... but the prior MS kit is gonzo and I now own the rack. FWIW

I have made my own rack, machining stainless steel 4cm dia spikes + screws on top, copying a basso design.
Tried 4cm thick solid wood shelves for two years. It does affect the sound vs the floor or just a whatever stand providing better vibration isolation. Just switched the shelves to 3cm thick cnc machined acrylic. All i can say is wow, that is a much better "dampened" material than wood, or at least for my system. It became quiter and rounder. Racks do matter for sure.
