Lewm, The brilliance of the LT is that it is using the energy from groove friction to drive the arm! Friction pulls the horizontal bearing platform forward and a magnet underneath makes sure it maintains the right position.
Uberwaltz, I am not entirely sure but I think the alto is a version of the CB.
The CB is as good as a pivotal arm can get for several important reasons. 1st is the vertical bearing is at the level of the record which limits warp wow. 2nd is it is a neutral balance arm. You can draw a line from the center of the counterbalance through the vertical bearing right through the center of the cartridge. Most other arms are static balance arms which always try to fine one level whereas a neutral balance arm will stay where you put it and won't start bouncing. 3rd. It has a brilliant magnetic anti skating device. No friction. 4th it is not a unipivot and has excellent bearings. Need I say more?
