I haven't tried it but it shouldn't have an effect on effective mass.One could also consider the tonearm wand to be the tightrope walker's balance bar. The rotation is on the vertical axis. so placing the weight of the bar (wand) at the extremes will have the same effect. The wand will not easily rotate but it the mass is centered close to the pivot (vertical axis) then it will rotate more easily. It's total mass can more easily be moved left and right.
All things being equal my Schröder arm sounds better with a heavier headshell (I have a couple) and counterweight moved further from the pivot than the opposite.
A few grams of additional headshell weight will not generally lower the resonant frequency significantly but will allow the c/w to be located further from the pivot. I know it's blasphemy. But considering the results I and some others have achieved with locating the masses at the extremes I can't imagine the leadweights at the pivot would have the same results since they are located at the pivot they shouldn't add to the mass thus not changing the inertia. I'm not saying it doesn't do what is claimed but ask why?
But now I ask where is the inertia the greatest? Inertia being the resistance to movement. That object with the greater mass has a higher resistance to movement.
The stock 300 C/W is 100 gr the HWs are 145 gr (at least one of two I have) and I also have a special "Lightweight" that is 110 gr. So the heavier HW will lower the effective mass since it is on the negative side of the pivot point.
Maybe those outrigger weights should be "way out there", huh? What do you think? I'm serious.
Cheers!
