I think that good inspiration can be found if we look at how cutting lathes are constructed or outside of the industry, we can look at how milling machines are put together. These devices are required to hold a fixture precisely in place relative to the work piece, (record blank or machined material), whilst being dynamically loaded. This is exactly what a TT is asked to do.
No issue at all with a suspension if the siting of the TT dictates. My installation is basically fixed to the concrete floor and mother earth and I believe that this approach yields good results. Of course in most situations this technique cannot be used, so a suspension is a good solution.
Interesting re the SME's, ok you can see their entrails but their is a single structure carrying the platter bearing and the arm. In this respect they are pretty conventional.
However the box that encloses it all is missing. This is likely a good thing.
Damping is a real can of worms. It's use can yield fantastic results or it can suck the life out of the sound faster than a death eater in a Harry Potter Movie.
propagation speeds.
Yes in this case transmission velocity of sound thru the material.
for example: acrylic is around 2700m/s
copper is around 4600m/s
