Dear Mid,
Do you have the standard JMW9 or the Signature JMW9? The reason I ask is that the standard JMW arm can be a bit light and on the edge for compliance compatibility with the 501 II. We generally recommend to our customers considering purchasing the VPI 3gm head shell weight for the standard JMW9 arm followed by adjusting the tracking force to 1.8 gm for top performance.
The extra 2 grams tone arm mass the JMW9 Signature offers matches the Shelter better and no extra tone arm weight is required (we still recommend 1.8g tracking force here as well).
Hope this helps
Dan
