Dear Raul, a very interesting point.
You are right - the effective mass does indeed increase when you move the cartridge away from the pivot/bearing. The position of a given cartridge does have some influence on the resonance frequency. Whether it is enough to really contribute to the sound itself has to be explored. The effective moving mass of a pivot tonearm is also (sometimes very drastic...) affected by the weight of the cartridges body (Koetsu's stone bodies.....) and/or the weight of the headshell (lightweight Orsonic AV-11 vs. FR S/3 for instance - a difference of over 21 grams !!!).
Both these units do "sit" at the very end of the "balance gauge" and thus do contribute very strongly to the effective moving mass.
Very interesting point indeed!
This too is one of thereasons why the torsion resistance of a tonearm is so important - the further away the cartridge is, the higher its influence on the mechanic resonance behaviour of the tonearm.
