I don't share your observation. Have you try floating your arm and then play around with the connector wire i.e. twisting and untwisting the wire to observe how much influence the wire actually has on the arm movement? I have no problem with the tracking of my JMW.
VPI Tonearm connector wire and record tracking
I have found that the bend in the connector wire from the tonearm to the junction box has a MAJOR influence on the trackability of the tonearm. it has tons to do with how the stylus tracks or SKATES across the record. If this BEND is not in an optimum position (that changes all the time as the tonearm tracks across the record), it will dramatically affect how the arm/stylus tracks the record especially on the inner grooves. I find myself bending this wire back towards the platter as it will bend away away from the platter in time. Has anyone else made this observation? Is their anywhere else this wire could have been located to have lass impact on tracking? It is my observation that the arm would sound much better if this wire were located someplace else.
