Goatwuss, I would have thought the medium compliance Jubilee (16cu) would be a good match to the JMW9 - at least from a low freq resonance perspective.
Is it possible that the JMW9 doesn't 'like' the heavier weight of the Jubilee (10.5g)?
For reference the Benz L2 weighs 9g and AT33 weighs 6.8g.
Looking at the specs the AT33 would appear to have medium compliance (at 10hz) and low weight, which perhaps works better with the JMW9.
When using the Jubilee in the Graham 1.5T, I always used the heavier counterweight - the Phantom 2 comes stock with a large diameter heavy C/W located close to the pivot - ie designed to work with heavier cartridges. In effective mass terms the 1.5T was supposedly around 11g, and judging by the lowering of fundamental resonance with the HFNRR disc, the Phantom 2 has a somewhat higher effective mass.
If the JMW9 does prefer lighter cartridges, then a ZYX at 5g and 15cu could be a just the ticket. Best to ask Doug, I have no personal experience with the ZYX (though I once owned their grand-daddy the Monster Sigma Genesis).
