The Zephyr is the perfect match for the 9 Sig and 10" arms, which weigh more. The best bang for the buck cartridge for the 9t is the DV 20x. Don't believe me? Just call VPI. Adding mass with weights or screws is nonsense, never worked for me no matter what I tried.
VPI Scout cartridge compliance
I have acquired a VPI Scout with a JMW-9t (not signature) tonearm. The table didn't come with a cartridge, so I have been using a Shure M97xE that I had laying around (and it works amazingly well). I've been reading a number of forums that state a JMW-9t arm needs a medium to high compliance cartridge due to its relatively low mass. I've also seen literature for the low compliance Soundsmith Zephyr that states it was designed specifically for VPI arms. Which is right? What do I want to accomplish here?
