I stand by what I wrote above your post. Yes, the designer of the RS-A1 does claim to have done away with the "inside force", but in fact there still would be an inside force or skating force at all points on the arc of the stylus tip where the cantilever is not tangent to the groove. At that one moment in time when tangency is achieved, there is no skating force, I agree. If there is a flaw in my logic, I welcome correction.The RS-A1, in particular, does have itshead shell mounted on a unipivot, which allows free movement in the lateral plane and in theory the headshell itself may choose its own offset as it traverses the groove, thus maintaining tangency at least some of the time, but in actuality the signal wires between the cartridge and the arm body impede free movement around that pivot point. Thus I have doubts that it self-corrects for inside force.
EDIT. Upon further thought I realize I was wrong in this last paragraph. If the headshell does passively pivot to hold tangency, then the fact of its pivoting creates a headshell offset angle and thus generates an inside force. No free lunch.
I own an RS-A1, and it punches way above its weight with an MC (low compliance) cartridge, for sure. I have yet to try it with a high compliance cartridge for fear of damaging the cartridge suspension; there's too many ways to screw up while mounting the cartridge and cue-ing it.
