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 ?

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.
