tone arm with 10gr mass with 15 gram weight cartridge?


i read about arm mass/compliance match  .
what about arm mass/cart weight?

Some manufacturers use "compliance unit" or CU as simpler abbreviation, but it means exactly the same thing as the others.

 

what is important = Resonance frequency within 7-12Hz, mostly it would do the trick. (The RF has to fall down into a precise interval of frequencies: some say between 8 -12 Hz, but reasonably it would be better between 9 -11 Hz).

And yes the general rule is:

a moderately high or a very high compliance cartridge to a low mass arm (up to 10gr).

a moderate to low compliance one to a moderate mass tonearm (11 -20gr).

(Screws are always added to the arm mass - something between 0,5-1gr).

A cartridge having 5-10cu is considered a very low compliance cartridge, a range between 10-20cu is medium compliance, and values above 30 suggest a very high compliance.

and what about the cartridge weight to match the arm mass?

Make sure though that counterweight is ok to balance the arm.

but how do i convert cu to the values that manufactures give?
and what is the effect of the cart weight?

μm/mN=...X10-6cm/dyn=cu

effective mass of tonearm, cartridge mass and cartridge compliance, should produce the desired resonance frequency.

and at the end of the day if sound quality is good (most important) then you forgett all the formulas.
