@bensturgeon, email Johnnie at Audio Origami in England. He knows all about that arm (a favorite of his). As I recommended earlier, a better route is to send him your Zeta for a complete internal-rewire, terminated in RCA plugs. Why anyone would voluntarily put an extra set of jacks/plugs/solder joints in the path of the tiny output signal of their pickup is a mystery to me. Those DIN plugs are awful!
If you don't want to spend whatever Johnnie charges (he cleans and adjusts the Zeta when he rewires it, with either copper or a choice of two silvers), the Incognito rewire kit is a good one (using Cardas copper, I believe), and the shielded cable coming out of the bottom of the arm is terminated "correctly"---on RCA plugs!
