JMW-9/Cartridge Problem

I just installed a Clearaudio Sigma (4.5gms) on a JMW9 the other day. Clearaudio supplies a lead shim to add in case the counterweight is not light enough for the cart. I don;t know if VPI makes a counterweight smaller then what is supplied with the JMW9. I know they have heavier but not lighter counterweights

I had the same problem using a Karat with my JMW-9. I contacted VPI and they sent me a headshell weight at no cost. Adds weight AND mass. They also recommended against a lighter counterweight as it will further lower the overall mass of the tonearm.

Same problem here, as well, did the same as Jorjen as got the headshell weight from VPI, works well.
