Confused about compliance matching with airbearing


Chrome doesn't let me post more than a paragraph, so let's try again.

I am ordering a Soundsmith Voice. I currently use a 20cu Grado with no issues, 10hz vertical resonance, on an MG1 airbearing.

Petere advised against the 28cu model which confuses me because Trans-Fi owners are use 32cu carts with what seems to be much more lateral mass.

Should the horizontal effective mass be high in order to use high compliance?

"Keeping the wand short reduces resonances within the arm which typically colours the music. It is probably one of the major influences contributing to the overall sound of a tonearm. Manufacturers of conventional pivoted arms go to great lengths to try to eliminate resonances. They have a hard job!
Together with a lightweight slider, Terminator has the lowest lateral inertia of ANY airbearing tonearm on the market weighing in at just over 80g including the saddle, counterweight & cartridge, allowing safe tracking of the fussiest high compliant cartridge."

Yeah, I do think the counterweight was overlooked. The damping trough is attached to the horizontal moving mass asemmbly....interesting.
Airbearings have a much higher lateral mass than fixed pivot. Seems Trans-Fi is about 80g (stock), MG1 appears to be about 65g with Grado. More worried about stressing the ruby cantilever with a really high comp. cart.
The ET2 is quite low mass then. I'm at about 60grams with cart, counterweight, and entire arm assembly on the MG1.
