TTWeights closing their doors

There is a guy in Germany who sells replica ms cu-180 gun metal copper mats.
 They are supposed to be excellent.

I own a ttweights momentus supreme and really love it. It sits on a Halcyonics type active anti vibration platform and feel like the combination is excellent without having to reach into the 6 figure turntable category.

I got the table before the rim drive was available so it’s the 3 belt version. (I also rotated it 90 degrees so I can use a 9" arm) I’m wondering how much a difference the rim drive makes on a 70lb platter with flywheel effect of the periphery ring (I think I have the most elaborate they ever made)

This was also before the copper platter was available. Mine is multiple layers of aluminium and composite, which was supposed to damp vibration. It’s also such ingenious design since no part of the 150lb table weighs more than 35lbs.

But I also own a copper platter add on they used to to sell a long time ago to use on another table (Maybe its 1/4 inch thick)

I never tried putting that on top of the momentus supreme standard platter but I should experiment. I’m wondering what the benefits would be and would I need a mat between the copper and the LP. The original platter’s built in top (which might be carbon fiber) was supposed to be of similar density to vinyl to create the ideal interface.

I also wonder if I should order extra belts or any other wear items while they are still available.

I was under the impression they were long gone?
