TW Raven Owners: Set Up Questions

I am curious about wall mount shelf. My apartment has solid concrete floor with tension cable runnig through them. The floor is very solid with a layer of MDF and solid oak floor on top of concrete layer and is supposed to support about 400 kg per sq meter. The stereo equipment is placed near outwall of the apartment which is non weight bearing wall with windows and basically a brick wall. In this case, the floor is much more solid than the wall in my opinion. Foot fall is never a problem. In this case, would I still expect the wall shelf to be more benefitial? The factory bench/granite top that I used weight in at almost 100 kg.

My apartment has solid concrete floor with tension
cable runnig through them.

This is called a
'prestressed' concrete floor and is designed to allow greater spans between
supports, with thinner floor thicknesses.
It is achieved by reducing the amount of steel reinforcing in the slab and
substituting steel cables (within permanent sleeves) which then are post-
tensioned.......after the concrete has initially cured.
It essentially pre-cambers the concrete slab so that the 'dead load' brings it
back to horizontal.
These slabs are becoming more like 'membranes' and because of the spans
they allow.....can actually bounce?
With the right equipment one can hear the structure 'singing' or 'moaning'?
They are possibly the worst type of floors on which to mount audio
equipment....particularly turntables?
If the outer brick wall is non-load bearing.....it must be supported either on
the floor itself or a concrete beam structure spanning between supporting
columns?
If the latter.....it is less prone to movement than the prestressed floor and
fixing a wall-mount shelf to it (as close to a column as possible)....will be
preferable.

Say what?

I am very confident that 3-5 Shakti Stones below, Shakti Online, teleportation tweak, liquid ceramic cables, clever clocks or brilliant pebbles will raise the table far above ultimate level.

Shakti stone will take away air not a good tweak.
