Audiofeil,
It seems there is more of a difference than just the Nordost Valhalla wire between the VPI JMW9 and the JMW9 Signature. As described by VPI "The JMW-9 Signature tonearm builds on all the advantages of standard JMW-9 unipivot tonearm. The JMW-9 Signature tonearm is completely wired with Nordost Valhalla internal wiring! It also uses an improved bearing assembly with viscous damping, has added mass for better resonance control, and adds fine adjustment of tracking force on the rear stem of the arm. It even has VPI's newest addition: mechanical anti-skate control!"
