Dear Ralph: +++++ " " If the arm is mounted on a separate 'island', it will be impossible to reproduce the LP exactly, as any differences between the platter surface and the arm base, for example microscopic vibration or resonance, will be interpreted as coloration by the reproducer... " +++++
Maybe I'm wrong or I don't understand some issues on your statement but let me add some thoughts about that I think need further explanation by you or any one that want to do it with the precise answers:
according your statement that " microscopic distortion " has enough " intensity " for the cartridge can pick-up through the TT mat and LP.
This means that independent of what happen with the tonearm ( please forget for a moment on the tonearm subject. ) that platter distortion will be " taked " by the cartridge through the mat+LP: right?
Now, if the tonearm is atached on the same TT estructure/plinth then that distortion will be pick-up by the tonearm it self and " communicated " to the cartridge in addition to.
What all these means is that the cartridge pick-up not only those TT platter distortions but additional from tonearm too on the same generated platter distortions.
What happen if the tonearm is on a stand alone base?, well that those microscopic platter distortions will not contaminate through the tonearm too.
can this be an advantage of a stand alone tonearm arm board due that exist only one distortion focus ( TT platter ) instead of TT platter and tonearm?
+++++ " Absolute rigidity between the LP surface and the cartridge body is paramount! That requires no slop in the arm or platter bearings, and that the platter, plinth and arm tube are both rigid and acoustically dead. " ++++++
agree but this is true for either approach and the stand alone tonearm board IMHO not preclude that your statement be achieved.
Ralph and dear gentlemans I'm not promoting $$$$ nothing on purpose and certainly I'm not entilted or go " till I die " for the naked TT project and stand alone tonearm board.
I just want to learn and try to confirm or not the virtues on our approach that till today is ( for the ones that tested. ) workink just great an better than the other " normal/orthodox " alternative.
All of you know my attitude that not think always on orthodox/inside the box way and yes the naked project ( like Halcro name it. ) is part of that way of thinking.
We are not " deaf " in the same way any of you are not and I'm sure that if we heard differences, not tiny ones I can say, any one of you could hear it when decided to test our approach that could be yours.
I respect all opinions but seems to me thay opinions like the one from my good friend Lewm where he is against stand alone tonearm board because " theory " say is a " wrong/bad thing/approach " ( because that boat explanation. ) with out tested by it self only could create " confussion/mix up " in other persons where is not necessity to do it.
My take here is to test by one him self to understand what is down there instead to speculate about.
Ralph, do you already tested?, if not try to do it and make the comparison and tell us if you heard/hear drawbacks in quality performance level with the stand alone tonearm board.
As anything in audio not all is totally black or white but in between.
+++++ " acoustically dead... " +++++
like you many of us use those words in audio but what those words need really " means " for have validity in our subject.
Acoustically dead on what we are discussing means for me a " stage/scenario " where the cartridge can't reproduce or can't take it a " distortion " coming from tonearm/TT or elsewhere or maybe that could be picked-up by the cartridge with no audio reproduction influence.
Till today I don't know any scientific studies on that subject with different phono cartridges in different scenarios and with different in duced kind of distortions.
So, for me these " acoustically dead " words has no real significance other than a desirable audio factor.
