@lewm you are correct, actually the most correct I have seen for a long time in your statement "no one is telling me what to do", I will reciprocate it with the passion others express about archaic, halcyon ideas that have certainly moved on in other circles of thought.
I am an individual who likes a first hand 'sit in front of' experience, then I make my assessment. I don't pretend I know what is the best and express a Boorish behaviour toward any ideas from another that challenges experiences and assessments that I am comfortable with.
As for the Base Board to Mount a TT and Standalone Tone Pod on.
My referencing a Base Board is how I have thought the methodology through and would choose to mount the Two Parts being interfaced.
As stated in a previous post, the board will be best if it has a Stable Property, ( again only my idea for this), it will with today's experiences to draw on also be a for the better if the Board has good damping and dissipation properties combined with being stable. This is not to be a statement to tell another if they do different they are wrong.
It does offer a alternative to an individual, if they have not thought of this methodology and choose adopt it, to see if a benefit can be attained.
There are many methods adopted today to control a transfer of energy not only one
As stated before, the TT Designs seen today and the methodologies selected as part of the design, to mount/interface the Tonearm are varied (the designs are way to varied to even be considered they are born from a one methodology only approach).
Tectonic Plates are what they are, they keep other parties with a passion for this field of interest extremely stimulated as does Marine Science and Astronomy.
All Three are natural, and all can have an impact on vibration transmission that can impact on a Man Made Product.
Tectonic Plates being used as means to describe a Set Up of a HiFi Device and Supporting ancillaries is so extreme it is ludicrously off the scale.
Is the next attempt to prove a point, using off the scale ludicrous as the parameter. Is where it is stated that Igneous Rock used in System, as a Plinth Material and Standalone Tone Pod Material will accelerate the convection and a Mini Mounting Range will form within ones lifetime in front of ones eyes, a ravine might even appear during one Albums replay.
Comparing the Naturally Created Tectonic Plates convection to a Platter Spindle and Tonearm that are 'not' mechanically fastened to the same material, hence, 'not' being mechanically coupled, and as a result, able to create a convection as seen in a Tectonic Plate is utter Cod's Wallop.
If a TT and Standalone Tonearm Pod had shown a movement toward each other at a dimension of Two Inches in one year in my own home, even if a Jack Hammer Breaking Out, next to the room with the equipment. I would be calling 'Ghostbusters' as a Meddling Poltergeist would be the most feasible explanation for the cause.
