So even with a 60hz electric bass riff, the needle is accelerating upwards in the groove pushing up against the cartridge. On your underhung model it is lowering the effective mass at the cartridge and reduces the vtf.A warp or dish would create more visual excitations.
By centering the median mass of the counterweight in the same plane as the stylus you are providing the minimal vtf fluxuation and gaining the highest tracking.
The software we are running is extremely powerful. It is configured on a 128 bit unix processor and we can examine extremely minute stylus movements and see what it does to the EM at the cartridge interface.
I started exploring this because I could not understand why my Grado Ref Master had such significant sibilence on a medium massed tonearm, and reduced on the Magenepan Unitrac low mass tonearm.
It was the effective mass at the cartridge and the compliance of the stylus related to the inertial moment of the tonearm which improved tracking.
Such fun!
