TTW MOMENTUS MOMENTUS "The MONSTER" Rim Drive


I must say interesting indeed - anyone happen to have one or had a listen? Any initial impressions

Some specs ...

- 99.999% pure Copper platter weighs in at 88Lbs 40 Kg's

- Total weight of the whole table tipping the scales of 200-220Lbs

- Bearing Shaft is Pure Micro Grain Carbide .5 inch diameter x 1.5 inches deep

- DC Servo Direct Rim Drive Super Torque with 24,000 pulse drive control (each revolution counts 24,000 points for accuracy and the MOMENT of inertia combined with the rim drive provides perfect rotational accuracy

Lewm, looking at the rubber on the motor's shaft it does not look like a precisely machined surface, but I may be wrong. I'm also wondering how they engage/disengage the motor?
I would think that with a rim drive o-ring with a durometer of about 60 slightly pressed against an 80lbs platter would cancel out any slight out-of-roundness of the o-ring. But if not, a $25K table should come with a high precision/machined O-ring.

Also, I believe that the table can be easily converted into a thread drive system.
Brf, you can think...when you start to listen&measure it can be adifferent experience. I'd not waste my resources on precisely machined copper plate without a mathing rubber surface...and we haven't touched the motor yet
I also suspect the thread/belt drive and idler/rim drive have a different physical optimum of the motor strength/platter inertia, so I doubt one can have a universal solution here, as they propose.
I would be extremely concerned with resale value, with TTW models constantly changing, obsolescence will occur quickly. TTW pricing structure is questionable as well, determining retail and 'street' price could leave a deep hole in your pocket if things don't work out. Seeing TTW's silly Jelco remodeled 'Eliminator' tonearm also brings me to question what other silliness is occurring. In speaking with Larry at the TAVES hifi show last year I understand he doesn't believe in resonance control, just tolerances and machining. This again has me concerned that his methodology is potentially flawed. Undoubtedly the machining quality is impressive, I am afraid however that it may end there...
