The 312S arm uses gravity as the VTF provider whereas the V-12 uses spring pressure.
Having forgotten to re-tighten the counter-balance weight less than a quarter turn of the locking screw on my 312S arm when adjusting the VTF, I wondered where the mids and highs had disappeared to (relatively speaking). Therefore, one suspects with a resolving system that you would have some minor differences between the passive 312S suspension and the active V-12. Whether its good or bad will depend on you.
I chose the 312S arm as it came with the SME 20/12A turntable.
