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!

That is a fantastic and clear explanation. Thank you. 
 

I think I intuitively understood this by alternating soft (felt, Sorbithane, neoprene) with hard and heavy (marble). 
 

with my outboard crossovers, I have them on the floor behind my pure audio projects. Their sound isolation is currently: sandbag —> stone block —> light weight wood (mainly for mounting the crossover and controlling cables) 

think this does the trick? Could be improved?

That is an amazing integration of electronics with vintage / wood / stuff. It almost makes the cold boxes for electronics disappear.

thanks for the compliment. Wood, and Donna’s Stuff makes a difference!

I cannot tell you how long we looked until we found that wood and glass rack, it was a floor model in the basement of one of J&R’s buildings near City Hall, downtown NYC. They were closing and agreed to sell it.

The end panel legs are a poor design for stability, but my fix solved that.

It was CDs, no TT when we found it. I promised Donna she could use the top for plants, then I got back into vinyl, needed to keep my word somehow, added the large plinth TT on top and stacked my SACD player and Remote Line Controller on top, 

I put felt on the bottom of two large trays for her plants, so the plants can still sit on top, one tray of plants move’s in seconds from the TT dust cover to the R2R deck’s dust cover, depends on what I’m playing, they always get daylight.

Typically the speaker is more to the side, does not block the R2R, but sometimes, I move them further from the side walls as shown here. Happily the wood floor is perfectly centered, so I can use the grid for matching locations each side
