Tonearm mount on the plinth or on Pillar ?


Folks,
I am looking to buy a custom built turntable from Torqueo Audio (http://www.torqueo-audio.it/). They have two models, one with a wide base plinth where the tonearm would be mounted on the plinth (as usual) and the second is a compact plinth where they provide a seperate tonearm pillar to mount the tonearm. According to them the separate tonearm pillar version sounds more transparent and quieter because of the isolation of the tonearm from the TT. My concern is whether seperating the tonearm from the plinth would result in a lesser coherence in sound ? Isnt sharing the same platform results in a more well-timed, coherent presentation ? Any opinions ?

In a typical cutting lathe is the cutting arm mounted on the same plinth as the platter or is it on a platform ?
Dear @pani: Now that you have several opinions on your main subject thread: which was your choice?
Dear Raul, the fact that this question occured to me even though I am a layman when it comes to technicalities of analog playback is an indication that I value that ultimate coherence of sound over the last word in transparency. Some of the most coherent and musically correct sounding decks I have heard, all have tonearms mounted on the plinth even though they have all the engineering prowess to build a seperate tonearm pillar. The simplicity of an integrated design brings about a simplicity in reproducing the music too IMO. I only wanted to confirm it by this thread. I am happy that there are many more who think like me including an audio designer like Atmasphere. If I was allowed to try the seperate tonearm pillar + plinth I would have happily taken the trial and come to a conclusion but when I am buying blind I will go by the proven practice of getting a single wide plinth with tonearm mounted on it.

Thanks everyone for this lively discussion. Please continue if you would like to.
Pani,
Perhaps you should take note of an audio designer who actually designs and sells tonearms and turntables.....
Someone like Frank Kuzma who makes the 4 Point and Airline tonearms and whose top-of-the-line turntable uses a separate armpod.
I’d be hesitant in calling Frank a fool....
I am not challenging anyone’s hearing or designing capabilities. I am only saying that if I have to buy blind I will buy an integrated system rather than separates.
Now here is a serious new turntable...

Dietrich knows a thing or two about turntables, arms and cartridges.
And gosh....what are those?
They look like tonearm pods and did he say in the interview that the tops of the pods are totally isolated from the plinth and structure?
I saw that video. The tonearm pods are themselves on the same plinth as the turntable if I am not wrong.

So then, is this setup some type of Optical illusion ?

That Verdier setup is incorrect. I have owned the Verdier too and have tried various setup configurations. In the setup cited in the link above the motor housing and the turntable are placed on different platfoms, one is on a vibraplane while other is on a regular raised platform. This may give the sound some added transparency due to the seperation but they dont sing like one. The coherency is affected, I have tried it first hand. Probably the person who set it up would never agree to this because he first of all doesnt believe this can happen (hence he set it up like that) and secondly he did not hear this problem after setting it up like that. With all those expensive tonearms, cartridges, isolation platforms, one has invested very well and it is expected that he knows very well what is doing but simple things are some times elusive
The Resomat is indeed a contrarian design in that it specifically decouples the LP from the platter, whereas most platter mats make an attempt at coupling to facilitate the dissipation of spurious energy delivered into the vinyl by the passage of the stylus in the groove.  

This is again against the principle of "closed loop". I have the resomat too and it does bring a lot of goodies due to the "isolation" of the vinyl from the vibrating motor/platter, especially in terms of reducing noise floor and presenting a more airy sound. But music looses on the timing aspect, it doesnt sing as one, probably due to the decoupling. I have since moved to a Funkfirm Achromat which is the best compromise I have heard yet. And yes, it tightly couples the vinyl to the system.
