In Reply to: How or why would anyone design an arm for a specific posted by jnorv on November 13, 2006 at 10:46:14:
the offset angle is fixed by the headshell design and not adjustable, for all practical purposes. Also there is the concept that the offset angle and the angle of the bearings should be the same.So as it turns out virtually every arm is designed for a specific set of parameters.
An arm like the Schröder has no bearing offset and the headshell/cartridge offset angle is infinitely adjustable (or more than one would ever need) and it has a very long adjustment for effective length/overhang and the base (on some models) is eccentric so the pivot to spindle distance can be easily adjusted too. With this arm you can literally use any pair of null points, effective length you desire. I use mine with the Stevenson type 1B pair of null points.
