@karl_desch, @sbank, The Kuzma screw down clamp is a reflex clamp. There is absolutely no reason to change it. I do not think you can unless the SME clamp uses the same thread. The Sota and Basis clamps are not for turntables with threaded spindles. Their clamping mechanisms might roll the thread and ruin the spindle. Spence, isn't your Nova a vacuum unit? If so you don't need any clamp at all! If you have to use anything a plain record weight is fine. My lead filled Cocobolo weight is just for show. I like looking at wood. Sota tried to sell me a reflex clamp also. Donna, bless her heart will try to sell it to everyone. The Sota tables are designed with the weight of the clamp in mind. My Cocobolo clamp weights exactly the same as the Reflex clamp for that reason but, I do not have to fiddle with a mechanism. The weight just plops on. @rauliruegas is right. The Basis clamp has a better mechanism and is beautifully machined but it is twice as expensive. it is however a pretty thing.
Karl, Which Vibraplane are you using, the 2210? The MinusK is the gold standard but I see no reason why the KSI shouldn't work and you can't beat the price. It is great that you are keeping this in mind. Now all you have to do is make a dust cover for the whole affair. As long as the dust cover is not attached directly to the turntable you can use it during play and further isolate the cartridge from the environment. Keeps the table nice and clean also.
