chakster, ''the key to using the arm with high compliance cartridges
is to get the counterweght as close to the pivot as possible''.
This means, according to me, the question about ''universal arm''.
I own Sumiko 800 ( ''the arm'') with 6 counterweights meant not
so much for ''compliance'' but well for different cartridges weight.
Those 6 are meant for cartriges of 6 g till 26 g. But back than
people bought just one counterweight corresponding with ONE
cart which people used to own. That is why my sample is so
rare.
I started an thread ''on what there is'' and got all kinds of reactions
except the ''relevant kinds''. Well ''there is Sumiko 800 with 6
different weights '' but its ''existance'' make no sense when
nobody is aware ot this ''fact''.
