Dover, So what is your turntable of choice, if you revile both belt- and direct-drive? As far as I know, that leaves only idler drive, which has its own issues. All forms of tt drive have positives and negatives. Execution of the idea determines the differences among turntables and what makes one turntable of one type better or worse than another turntable of the same or different type. This shouldn't make anyone angry. Anyway, what do you use currently?

I must be doing something right, if both Geoff and Clearthink are angry at me. Clearthink even used his signature triplicate warning system. (I mustn't "limit, restrict, or discourage...") Did you think that Geoff is some shrinking violet who needs to be defended lest he walk away in tears? Here's the thing, Geoff: Have you considered that we are riding on an enormous ball that is circling the sun at 67,000 mph, while also rotating about its own axis at about 1,000 mph, at the equator? My point is that the earth is our platform and everything is subject to those seismic vibrations with which you are so obsessed. Relatively speaking we are all in a sort of spaceship that is subject to the seismic forces. Therefore, relatively speaking there is no net motion due to seismic forces of a turntable with respect to a tonearm or cartridge or vice-versa.I'm surprised at you for getting so hot so quickly, but perhaps I struck a nerve.

Geoff, Enough already with the seismic forces. Have you figured out that no one is listening?

Chak, To your knowledge, is Toho still in the business of selling those accessories? The Torqueo stuff is beautiful (like a seashell, apparently) but not as substantial as Toho's.

Slowly, inevitably, this thread is backsliding into the old argument that was the central topic in the Copernican thread. I felt that over time (and months of haggling), Halcro's approach actually began to look like an idea I could like, so that eventually there was very little to argue about. And I went off on my rigid way with my tonearm pivot firmly connected to my bearing. It's easier for walking around.

Have you guys ever seen Halcro’s photos of the interior of his Halcro preamplifier? Something like that in black.

For the record, Nikola, I have never replaced or modified the platter on my Lenco. Along with the motor and idler wheel, the platter is OEM. I am in fact skeptical of those who have doubled up on the platter, using two original platters, one on top of the other. And I am not even aware of anyone who makes a candidate aftermarket platter for a Lenco idler. And finally, I don’t approve of doing any of those things, because I think the drive system was designed and conceived to drive the platter as is. Altering the mass might not be a very good idea. So, perhaps at sometime in the past, which I don’t remember at all, we may have had a disagreement having something to do with a Lenco, but it could not have been regarding my desire to replace or alter the platter. Without consulting anyone here ever, I did do one thing: I had the platter professionally painted in a vibration reducing paint. And then I placed 4 large O-rings around the circumference to dampen the purported tendency of the platter to ring. I got that idea from Win Tinnon, the guy who makes the Saskia.

Halcro, if your arguments are good, it’s really not necessary to be insulting.

I've heard the Doehmann Helix in a system with which I am very familiar. It indeed seems to be a fabulous turntable, perhaps the best belt-drive I have ever heard. My friend has since sold it because he needs to downsize and decided to go all digital. I could have bought it for a "nice" price, but even the nice price was a bit much for my blood. As to the independent mounting of the tonearm, I don't recall that it was evident. How did he make it look integrated with the turntable and yet isolate it? By the way, smart guys (Atma-sphere, Richard, and Mark) can differ in opinion, which does not make the persons on the other side of the argument "amateurs". If you wanted to make a list of competent designers who line up on one side or the other of this particular proposition, I daresay the "couplers" might have a larger contingent. But you and I have been over this before, and I have no beef with your preference, nor do I wish to argue about it all over again. Peace.

When I was building slate plinths for various of my turntables, I adopted the practice of not creating any tonearm mounting boards or accommodating for them. I therefore had to limit myself to surface mount tonearms, like Chakster says. These included the Triplanar, Reed, Dynavector DV505 and maybe a few more that I don't own. I bolt the tonearm directly to the plinth. Nothing moves. I am not saying this is the best way to go; it certainly is not the most convenient nor the most flexible, but I think it adheres best to the principle of coupling the tonearm pivot to the platter and bearing. For highest flexibility to use any arm any time, an outboard platform would seem best, if you're being pragmatic above all else. A very heavy outboard arm pod that sits on the same support structure as the plinth itself is probably an acceptable compromise as far as coupling.
