Tri-Planar Vll "SE Upgrade"

Yes, the damping trough was removable on the VII without affecting the armrest.  I didn't realize that had changed.

Hello All,
Thank you Peter at PBN Audio for confirming our measurement.

From my experiences, I would actually believe nandric's comments as many newer arms just do not seem to track as well as the higher mass arms for some reason.  I have heard it myself.  I have heard medium mass arms mistrack many records and then here the same records on a mission mechanic arm and they track perfectly.  I have never heard a FR-64s but it is a high mass arm, just like the mission mechanic.

The triplanar is the best otome I've ever used it's a wonderful wonderful products with wonderful company excellent top shelf support service Parts this is a Rolls-Royce of the turntable world what a wonderful wonderful item if it's a little out of your price range save up it's worth the wait

@tzh21y  The issue here is something called 'effective mass' which is the combination of the mass of the arm and cartridge, and how that interacts with the mechanical resonance, which occurs when the effective mass interacts with the compliance of the cartridge.

Regardless of the quality of the arm and cartridge, if the mechanical resonance does not fall within the window of about 7-12Hz, the arm and cartridge combination will mistrack and you may experience breakup even with moderate modulation in the LP grooves.

IOW, 'medium mass arms' has nothing to do with it. What your post suggests is that the medium mass arms you heard were not set up properly.

The Triplanar allows some adjustment of the effective mass, and so it can accommodate a fairly wide range of cartridge compliance.
