Thanks so far to all and especially for the link too.

Thanks.
I too have, after some dedicated time, spent trying out different footers under components, found differing wooden types of either boards or blocks, do impact the sound.
My rack is atop a Beech plywood base which just rests onto the top of the carpet the rack is spiked into Mahogany Squares which reside in between Beech & spike.
Im not too sure just how much decoupling is going on if I use spikes anywhere in the chain. Rather the thicker 7/16 pad, and ½ pile may afford some detatchment, onto that why not place a board of sorts, and use pods, pads, or roller blocks there for the speakers to rest upon?
My concern that way would be stability, and number of supportive/dampening devices that would be needed for the job.
My speakers are right at <100 lbs each.
Im liking this notion as itll raise up the speakers overall height, which for me, would be a good thing. and prevent further holes being punched into the wood underlayment.
In fact doing away 100% with spikes seems a plus to me in general.
Apart from what and how many, Ive seen some notes that reflect a tipped up tonal quality when roller blocks are used, as well as lessend bass depth and impact is that a general but accurate, consensus?
