Dear @atmasphere : According with my very high ignorance level there are some things that goes against your " scientific " test:Nothing at all. As stated previously, the stylus does not care where the difference is between the two- if the pillar is still and the platter bearings are not, its still a problem.
- as @halcro posted one of your premises is that exist movement in the stand alone pillar. Why don’t choose as premise that the pillar has no movement? what could happen at your scientific/theory?
- I have a premise too in my subjective " science ": that the holding cartridge tonearm must be aisled from the self TT " movements/vibrations " and air borne effects in order that those non tonearm " movements " can affect/produce additional distortions/colorations to the cartridge performance.Its best to isolate the motor such that its vibration is not a problem. Its also good to insure that the plinth is adequately damped. Beyond that I can’t comment on this passage as I can’t make out exactly what you are trying to say.
- according with your science my premise go against your theory because the tonearm has to vibrate exactly as the TT platter. So, if we have an integrated tonearm pod that does not vibrates at all then is wrong and add " colorations " by the cartridge.Its not ’my science’, its just science. Please reread my posts above- clearly you don’t understand them else you would not have said this.
- according that we need that the integrated tonearm pod/base has those same platter bearing vibrations. So, a well damped/dead one integrated arm pod is wrong and is wrong because till today exist no TT dead silent beairng platter.
I’m not talking about how noisy the platter bearings might be. Nor am I talking about motor noise. Please reread my posts above as you don’t seem to have done so.
- So, I infere from your science that it’s better not to aisle/fuly damps the integarted arm pod. I don’t know what I’m missing here but I’m not convinced that is better if vibrates evenly with the platter that if that arm pod stays deadly.
The arm pod can be fully damped as long as it is ridgidly coupled to the mounting of the platter bearings. Please reread my posts above as you don’t seem to understand this rather basic engineering principle. Could you also explain the word ’aisle’ as it seems to be a mis-spelling or mis-use.
- other of my premises is that the cartridge must be " aisle " from vibrations as we can. Now, the ideal scenario for a cartridge ridding job is to make that job with no single vibrations, this is imposible to have/exist.Ah- I think you mean ’isolated’ when you use the word "aisle".
If that is correct, the statement above is not entirely correct. It is true that it is good to isolate the turntable/pickup from vibration as best we can, but the cartridge must be held in firm locus at any time during its journey across the LP surface. If this simple issue is ignored, noise and coloration will result.
- starting from that ideal scenario next step could be to put at minimum all non-self vibraions that affect the cartridge job.You don’t seem to understand that if the platter bearings are noisy, no amount of vibration isolation of the arm will prevent the cartridge from making that fact plainly obvious! I’ve serviced thousands of turntables in my life and seen that played out quite a lot. If you have a noisy platter bearing, you should replace it with a functioning unit.
The bearing platter vibrations always affect the overall cartridge job as the tonearm/cartridge resonance frequency and the own tonearm additional vibrations and the feedback of all those vibrations and now we " need " that the integrated tonearm pod stays vibrating evenly with the bearing platter and this represent additional vibrations/colorations that are produced when in touch with all the other already generated vibrations because here exist a delay time on those same kind of vibrations and its amplitude are not exactly the same.
My God !!!!!!Your conclusion here is not logical and runs counter to real life! Do you not understand how a cartridge transcribes vibrations into an electrical signal?
We need additional integrated arm pod vibrations. Why and external dead silent arm pod is different of a dead integrated arm pod?
is it better/worst a dead silent arm pod integrated or not? or is better the one that vibrates evenly with the bearing TT platter with all those additional vibrations I talked about??
If the base of the arm moves in unison with the base of the platter bearings, the noise of the platter bearings will be much harder for the cartridge to pick up. If the same factor is on both sides of the equation, it can be canceled.
For you and the other advocates to integarted arm pod things are so " easy " but for me and other gentlemans are not. Please re-read all the @fleib posts where I agree with.
Vibrations or dead silent?, that’s the question.

I think the problem you are struggling with is the idea that somehow you are going to make everything perfectly dead silent.
In the real world this is impossible. No matter how dead you make it, there will always be some difference that you can’t find or fix. That difference will be interpreted by the cartridge as noise or a coloration.
Because of that in the real world a good solid plinth will beat a separate arm pod/pillar every time. Again, this is not to say that a pillar can’t give good performance, it is saying that a silent and rigidly coupled plinth will give better performance. You can’t beat the math on this one.
BTW, what I have stated above is also why an arm board on an otherwise solid plinth may not be a good idea. This is because if the arm board is of a different material as the plinth, it will be able to move due to vibration in a different plane. This is why we don’t have an arm board on our turntable.
Now if you have been thinking of a poorly designed plinth and comparing that to a separate pillar, then you are not thinking about what I am talking about at all. This is so important I’m going to repeat it:
