Rack Stack Vibration Isolation advice

Hello you fellow crazies....

 

I seek some advice on stacking my components is needed. 

 

I am restocking my components. Currently I have a wooden rack on cheap neoprene feet, some marble with neoprene feet beneath my components on two shelves. See here: https://www.dropbox.com/scl/fi/ybl9eltdoj7o94bx1gbap/IMG_8694.jpeg?rlkey=gflbkfb2hr2p494pr1ae01vv7&dl=0

I am needing some more clearance below with some small components added. I am thinking of raising the entire rack on a 1.5" wooden butcher block. My main question is what should I place beneath my butcher block, between it and the floor?

Option 1: Cheapo "Tertullus" footers with ball bearings: https://www.amazon.com/dp/B09P1BR54Q?smid=A22180QALJ57SP&ref_=chk_typ_imgToDp&th=1

Option 2: Neoprene Footers 1" high and / or Felt

 

The rest of the rack would consist of Stack Audio under the Marble which has the components. 

The total weight of the rack and components and marble is about 200lbs. 

 

What do you all think? 

Thank you for your input!

Below is the planned overall stack:

STACK:

  1. WOOD FLOOR
    1. TERTULLUS BALL BEARINGS OR
    2. FELT and / or (?) NEOPRENE
  2. WOOD BLOCK 1.5” THICK:
    1. 3X CS2 STACK AUDIO
      1. MARBLE
      2. PHONO PREAMP
      3. FELT
      4. NAGRA STREAMER
  3. WOOD RACK:
    1. TERTULLUS BALL BEARINGS X 2 AS FOOTERS
    2. FIRST SHELF
      1. 4X CS3 STACK AUDIO
      2. MARBLE
      3. DAC
      4. VROCK + VBIT
      5. 1/5” NEOPRENE
      6. MARBLE
      7. AMP
    3. 2ND SHELF
      1. 3X CS2 STACK AUDIO

+1 @slaw regarding Townshend. I recently purchased their isolation platforms and they are amazing. I’m a convert to decoupling over other methods. On the very low cost side I’d try the springs that are found on Amazon. I purchased a 4 pack and you can remove springs to get the appropriate resistance Vs weight. I’d put the Townshend’s under the rack and experiment with springs under individual components provided you have enough clearance. Happy Hunting , Mike B.

… so Townshend pods beneath the wooden butcher block… and the stack audios beneath the marble for my components on the rack?  
 

spatial king… I cannot read between the lines…. So how would the felt perform? And what do you mean by layers?

 

thabk you,

Cork Pads are one of my go to separators and used as a tier in the Support for the Sub-plinth my Racks sit on.

Years ago Spent Squash Ball as a Half Ball were used as footers under equipment. I was always led to believe Spent Hockey Pucks were similar in their managing energy, these would be a good dimension as a Rack Footer.

Do consider for the Rack Support, a Sub-Plinth built on top of a few tiers of different separator materials.

IsoAcoustics Mini-Pucks and Oreas work well under my main electronic components. At the suggestion of a friend, I use little squares cut from Ikea Gunstig pot stands under my power amplifiers. These are cheap enough to try under all components. When cutting, care needs to be taken with the metal magnets in the Gunsigs. Multiple layers of these cut squares can be used.

I did see a photograph of a rack that had been fitted with IsoAcoustics Gaia loudspeaker feet. For racks that take threaded bolts, this looks like an elegant vibration control solution. I think they would work for my Quadraspire racks and I have trying this out on my to do list.

Try some of these isolation pads. They have cork or a rubber compound in the center. They work and they are cheap
