Travbrow, My Kuzma Stabi Ref. has electronic speed regulation which I never adjusted because there is no need to do that. If I use the Kuzma clamp or not this has no influence on the speed. To check the speed I use the Clearaudio stroboscopic test record with the stylus on the record. BTW I check with both my tonearms : the Reed 2A ,12'' with Phase Tech P-3G and Triplanar VII with Benz Ruby 3S. Both carts with 2gr. VTF. The Kuzma has inverted bearing, the platter is 8kgr. while the total weight is 40kgr.
