    Default 13g headshell + AT33PTGii - a match?

    I've got my eyes on a headshell with adjustable azimuth and overhang:
    https://eu.audio-technica.com/hifi-p...ies/AT-LH13OCC

    But it would take the effective tonearm weight to 17.5g. Paired with the AT33PTGii (6.8g + 0.5g fixings), the resonancy calculator gives me a reading of 10hz - well inside the "green zone". If heavier headshells are not viewed favourably on this arm (being low mass), why does this reading look so agreeable? Anything I should be concerned about? I have an auxillary counterweight and KAB tonearm damper to help balance the arm and tame resonance issues, but just a bit cautious because of previous advice I've read to keep it light on the techie.

    Cosmetically speaking, these 2 bits of kit would really look the part together.

    Cheers,

    EDIT: This headshell appears to have fixed offset...not sure that will prove very helpful in doing ultra fine alignments, in the case of working with tonearm tolerances..

    The compliance of the 33PTG/II should be 17.5 (converted from Japanese 100hz specifications to European 10Hz) which would give you a resonance frequency of 6.418Hz.
