@mijostyn @wrm57 - wrm, my doppelgänger here, is right on with adding a "plate" to the Minus K. I use an HRS platform that I had prior to purchasing the Minus K. Particularly with my table, the Kuzma XL, which is machined brass, I would not want the "ringing" effect of metal on metal- the top plate of the Minus K is a plain metal panel. (I am using their large bench top model, BM-1, with the Minus K supplied stand, a nice piece of welded steel frame with phenolic top that has recesses for the Minus K feet). I assume mijo will use a slimmer version of the Minus K if it is meant to be concealed as part of a plinth. The BM--1 is a big beast.
Good luck,
Bill
