How to measure tonearm effective mass


Some of us who use high or low compliance cartridges fret about mating them with tonearms of low or high effective mass, respectively. Most of us rely upon data supplied by some manufacturers to specify the effective mass of their tonearms, but many manufacturers do not even supply such data. Does anyone know a simple and relatively accurate method for determining effective mass? We know what "effective mass" is; we want to know how to measure it.

Dear Lewm: +++++ " have correctly (probably) pointed out that the compliance/mass issue is not at all the sole determinant of a good tonearm/cartridge marriage. I suspect that is a very important truth. " +++++

why you have doubts about with so many testimonies not only on that MM thread but on other threads and even on proffesional reviews like that one that I pointed out in more than one ocassion review on Audio magazyne (1984) reviewed Ortofon MC 2000 cartridge. Well, maybe because you are " technical " oriented and like to know in precise way the why's, I would like to know it too.

Now, some way or the other we have to trust in the tonearm/cartridge manufacturer specs, yes maybe sometimes could be some errors but I think normaly are trusty numbers.

In other side, what I think we need is some one that take the task to " design " a mathematical/computer model that take in count any single factor/parameter/subject that has influence in the cartridge quality performance level and that could give us an " idea " of what to expect with a cartridge under " some/any " circumstances " where cartridge is surrounded.
Who say I take it?
