I own the, say, MK1 Kuzma Stabi Reference which is made for
one tonearm only and well 9'' long. The armboard is made as
sandwich from aluminum and acrylic and need to be ordered by
Kuzma for specific tonearm. However one can use 10'' tonearms
like Triplanar , Reed, etc., because their pivot is next to the
VTA tower which means longer distance to the spindle.
For those who want an second tonearm the use of an ''armpod''
is neccessary as well one 12'' tonearm. Both should be put at
the left back side of the Kuzma. I use the Reed 3P , 12'' as well
the armpod made by the Reed. The other tonearm is Sumiko 800
(aka ''the better Breuer''') 9'' long and with all 6 counterweights
meant for carts from 6 g till 35 g. Both arms are with fast headshells
such that changing carts is an exercise in frustration. So, sometime,
one ''really need '' an second TT + a toneram with removable
headshell before one can start his own cart collection(grin).
