@pryso Thank You for your contact, unfortunately I can't reply through the private mail as I can't access mails on this forum.

Making a contact through a private mail is fine, I assisted a selection of Gon Members over my period of membership through their contacting me privately.
A Plinth Design for a TT and a Structure Material used for a TT Plinth are two different entities.
A Plinth Design can incorporate a selection of materials, which might have different Intrinsic Properties that impact on a attractive coefficient of expansion (CTE) in heat or humidity being maintained.
Rate at which Shrinkage occurs to a material is also a consideration when moisture is absorbed.
A design can also be one where there is not too much thought in place, to show there is a discipline used to optimise the Critical Geometry.
When the above design is encountered as an incorporation into the Structure for a TT. It is inevitable that optimised set up will be quite difficult to maintain and a sonic will become compromised as the interfaces become lesser in their optimisation.
Choosing a Material as a Structure to support a TT can speedily remove some of the above concerns, if the correct materials are selected and used that are with intrinsic properties that make them noticeably stable in a cross a selection of environmental conditions, the need to be overly concerned about optimised set up conditions being maintained is much lesser of a consideration over time.
The next to consider is what is the want from the individual for the selected Plinth Material:
1, Is it selected to function as a Massey Material ?
2, Is it selected to be a Light Weight ?
3, Is it selected using the Materials Intrinsic Properties, supported through data, that shows the materials has a very desirable Damping / Dissipation for managing Mechanical Energies being transferred or alternatively managing local environmental kinetic energies being transferred ?
Each material type that can be adopted from the sections above will have their own unique sonic, as a result of how energies transferred though the material are managed and how the material itself is isolated from the local ambient environment energies being transferred.
How does a individual discover which id their most attractive material to have maintained as a Structure to support a TT?
In my case trial through experiencing many different materials as a Plinth, where a small selection of trials were carried out experiencing the same TT > Tonearm > Cart' in the same system on the same supporting structure for the system.
My selection for a Plinth Material and ongoing investigations into how to best attach a TT mechanical system to the Plinth, does not indicate I have discovered something that is ubiquitous to all tastes. I am very confident I have discovered a methodology that is the most transparent in use that I have been familiarised with, and that this is most favourable to my tastes for a sonic.
I can't inform an individual where their journey stops when it comes to getting on Bus and venturing into selecting a Colouration is most attractive to them, in this subject, most are very unique in what their preference is.
Each individual has their own stop where they get of the Bus.
Linn as an example has produced the Bedroc using a material type that is becoming more and more popular in use from a Commercial Entity or a enthusiast DIY Builder.
This material used in a Linn TT Design be a step further in managing ambient energy transferal, Linn have remained on the Bus and are inquisitive, in my opinion, they found a material that has attractive qualities, even though they overlooked some of the most attractive properties in what a structure should be when selecting the material.
My own experiences to date has lead me to using Resin Impregnated Densified Wood Board Material as the Plinth to support a TT, this material has excelled used with DD TT's, especially those from a Vintage Japanese era..
