Tang - Dave, Mike, Ron and Christian have an AS-2000 each.
By my arithmetic, that leaves a sole AS unclaimed.
Are you gonna do the decent thing?

my understanding is that some un-named person has claimed that 'other one' already. but they have stayed anonymous as I had intended to do....but could not.
it's interesting and ironic to me that as we approach the 'ideal' of the vinyl format, we get more and more simple, elegant (not easy) and less automatic. we are needing to accept that belt installation and the relationship between the motor and the platter must be tuned by ear. and as belts wear and stretch it will need to be re-tuned. and my own take on that is that it's wonderful that the musical art and it's essential timing is best captured by the ear.....and it will be a matter of personal tuning preference.
What about Mik guys, I doubt there can be a turntable he does not own

As I said, the world's greatest and potentially simplest analog playback system (plinth/air/platter w no solid bearing/motor) is SO dependent on setup/ancillaries.
Are we really saying that Sutherland Timeline will be less useful than subjective "tuning"?
Surely that goes against the laws of physics?
Marc, this is NOT what I meant to imply. I consider system "tuning" to be quite distinct from accurate and consistent platter speed. I do the former by ear and the latter with the Timeline. It is interesting that Mike has lived with DD tables, known precisely for accurate and consistent speed. There must be something else in play here.
Perhaps Mike can elaborate on what he means by "tuning" and the sonic effects which he considers subjective. I am also interested in exactly how different approaches to belt type (material, compliance) and tension subjectively effect the sound, particularly with this AS 2000 turntable.
David has chosen his belt and tension. What went into that decision and how would he describe it?
(...) There's only an inch between the motor casing and the plinth, not much free belt at all. Spin up and spin down depends on belt tension and the force of the first push, in my setup it's 90 seconds to reach correct speed and the platter will free spin for a couple of minutes or more by itself if I leave the pump on. It doesn't matter in operations when you can change lp's with the motor running, it doesn't miss a beat.

Even with a good push it takes 90 seconds? The belt should be fairly loose. Does the motor increase the speed gradually during startup?
However considering the capabilities of current synthesizer circuits we have now the possibility of creating a three phase drive with variable amplitude and optimum shape in each phase if desired, minimizing vibration and maximizing speed stability. As far as I see each of the AS controllers is optimally tuned for its motor. This has been done many times for two phase synchronous motors, only a few current turntables do it for three phase motors.
I tried the trick long ago for the low voltage, three phase small motor used in the Oracle premier - it could run perfectly and silently, but unfortunately the too small motor had low torque and could not run at the lowest vibration point.

Sure Peter
I just find it deeply ironic that what I consider the simplest tt on the planet may have the most complex adjustability on the planet.
It's a "good" set of challenges to have.
