TW Raven Owners: Set Up Questions

I use a wall shelf and have tried a number of isolation feet. The problem with heavy granite slabs is the wall shelf might be overloaded. You don't want the table falling off the wall.
I have used a number of feet, stillpoints, black ravioli, Herbies Isocups. the New stillpoint SS Ultra are marginally better than stillpoints+ risers, not enough to justify the added cost, but better

In addition to the above, granite can be OK if damped by gluing linoleum to the underside.

I have experimented with a variety of mounting possibilities for my TW AC 1, starting with a granite base(not good, a bit of ringing) to a HRS platform sitting atop an acrylic stand( not recommended). The AC1 has been tweaked with a BN PSU and motor. This required more real estate and led to a wall mounted 2.5" mdf shelf on brass cantilevers. Wall mounting is by far the best if it works for you. The AC rests on a HRS platform while the BN motor has a separate mdf platform and the whole package is on a wall mounted mdf shelf that can support upwards of a 100 kg !
Any of the well known iso platforms should work well. I would urge caution regd the feet. Any hint of rubber or non metal in contact with the feet can deaden the sound ,as I discovered. I have the HRS couplers that consist of a round metallic plate with rubber dampers on either side. Initially, I had the 3 TW footers resting on the metallic coupler sans the rubber damper on top.Sounded good but removing HRS couplers led to dramatic improvements.
Use only the TW arm board as opposed to a wooden armboard .
All the best

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.
