In his white paper on tracking angle error, does Mr. Firebaugh explain why he does not provide for end-user adjustment of stylus overhang? It would be a simple matter to provide slots in the headshell, rather than fixed position holes. All that he says about tracking angle error may be true, but it still does not explain why he seems not to trust the end-user. Further, there is another school of thought on the importance of tracking angle error. (I personally have no opinion; I am merely arguing from principle.) Moreover, if you say that this or that cartridge sounds "great" on the WT tonearm, this tells us nothing about the effect of tracking angle error, good or bad, on what you are hearing. I know from experience trying to help a friend to mount a Dynavector Karat on a WT Reference tonearm that the stylus overhang was way off, because the Karat has an unusually short cantilever. Ditto for the Decca mentioned above that sounds "great" on the Amadeus.
