Wow, I had no idea it is so sensitive. I have not heard this kind of report before about the Minus K. How does one put a level on the turntable platter to confirm that the platter is level? I imagine that the weight of the level itself will throw it all off unless you find the absolute center of the distributed weight and place the level in that exact spot. It sounds too finicky to be a practical solution to turntable isolation.
Makes sense if you have paid $$ for something like this, you will go to additional lengths to make it work and say it sounds great -- which it does. But I am not sure the finicky nature will be worth it - in my case anyway.
Getting the platter level is quite easy and I use a spirit level over the centre spindle - after the table wobbles around, its seems to go back to the original position - at least horizontally.
I am going to stick with this for a month before returning it to my mate. This should see if I am exaggerating its quirky day to day usability. Sonically its very good.
One thing that is quite cool. When you start the SP10 mk3 platter, the table floats/pulls quickly to the right and back due to the high torque of the famous mk3 motor. same when it stops on a dime - the entire table floats left and forward before coming to a stop.
