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 ?

Ralph is absolutely correct. It follows that the tonearm and the platter must be in communication, and the faster the better. Beryllium anyone?

Well, Ralph, your explanations are perfectly intuitive to me. 

When I replaced my TT plinth, a rigid coupling of the platter bearing and the tonearm seemed intuitively obvious - I used a sandwich of heavy, precision aluminum plate, with the bearing surfaces machined into a high precision match. Improvement was not subtle.

Your calm is admirable.

I propose that Ralph be enrolled on the calendar of saints. His restraint is supernatural - a miracle thrice renewed!!

Halcro, you ask if I run OTL. Well, I did, and they sounded fine, but I decided on home brew, where cost is less of an object. Before building anything, I decided to optimize the system (instead of the pieces thereof), and found that I could improve system performance by using solid state Class A, push-pull, with low voltage rails, which allowed me to safely remove the now-redundant protection circuits from the ESL's.

Amps better than OTL? Don't know - but the system sure is.
