Cartridge Change Overhang Difference-Fixed Headshell
I’m using a SME fixed headshell arm and an Art9 cartridge that was mounted with a Yip mint protractor. The Art9 mid hole to tip distance is 11mm. A new Art20 is stated as being 10.5mm. Opinions wanted as to use same protractor or not or Estimate the 0.5mm and shorten the arm, pivot distance. Note, this is not about the $130. That difference of 0.5mm would change the intended null points (Baerwald) and/or ultimately affect the sound in general shifting the distortion to slightly different points on the record? Thanks
Dear @bigwave1 : You don't have to worry about because that very small distance what it can makes is that instead to have Löfgren A set up you will have Löfgren B that several audioiphiles prefer over A ( Baerwald ).
Btw, very nice room/system you own. Congratulations.

@wlutke , Was curious as to the practical performance implication of the 1/2mm difference other than those known about different null points. Thank you |
Well obviously exist higher tracking error and this means higher tracking distortions. If overhang change in any geometry kind alignment it needs to change too the P2S distance to mantain that alignment parameters. The calculated set up parameters came from the input parameters in the alignment equations: tonearm effective length and most inner/outer groove distances to the pivot where you can choose between: IEC; DIN or JIS standards. At the end of calculation the P2S is the tonearm effective length minus the overhang and that’s why everytime that overhang it needs to change the P2S to mantain the lower tracking error/distortions.
