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

Perhaps I'm being thick, but if there is a difference in stylus placement once the two cartridges are mounted on your SME arm, don't you deal with that by sliding the arm in its base? The protractor used simply means you end up with the same geometry after you have done all that.

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.

 

Regards and enjoy the MUSIC NOT DISTORTIONS,

The Mint LP target is specific to the pivot to spindle distance. Since that distance hasn’t changed, use the target. If long or short of the target, be aware that the Mint’s null points and their alignment grids  will no longer apply.

@wlutke , Was curious as to the practical performance implication of the 1/2mm difference other than those known about different null points. Thank you
