In my all-Naim system the best and the cheapest upgrade was Mana Acoustics stands for SBLs. Speakers sit on a light platform which is "floating" on the set of spikes going from Mana frame to the platform, and four more spikes face the floor. So, I cannot figure out if SBLs are coupled or decoupled from the floor, but the end result is truly magical!!! Heavy granite slabs just lower the resonant frequencies, something I am trying to avoid in my professional business when doing microsurgery under x200 magnification.
My say: four spikes from your slab toward the speakers, four more toward the shelf. Then substitute granite slab for Mapleshade piece of maple.
Herbie LP mat worked marvels on my Sondek, also keep in mind that I am seriously biased towards Naim/FlatEarth sound... ;-)
