VPI 3D printed arm mod.

I understand that the 3D arm (which is considered one of the best arms there is), now has a (what is called - very major) upgrade.  I understand there is an additional pivot point on the left side of the arm (so it's now a kind of hybrid - not a uni-pivot arm any more.)  I was told that middle road cartridges sound like an Atlas (hyperbole?) with the new mod.  I understand all 3D's can be modified to the new design for 100 dollars.....wow.

Mat and Harry have replied to the Fremer article linked above by brf. Seems the mod will be user doable at home at not much cost.

VPI should just add pivot damping back, to the 3D arm, like their older JMW arms, which had no stability problems.

Pivot damping generally closes in the sound,  ,,eliminates the air, etc.  Cartridges are designed with their own damping...that should be enough.

Proper adjustable pivot damping has always given me an "across the board" sonic improvement with every cartridge!

It is a must have adjustment IMO!

I am very close to pulling the trigger on a Prime/Ortofon or Lyra combo after 6 months of vacillating. Would it be smart to wait until VPI offers tonearms with the mod already completed?

There's zero chance I'd attempt any major surgery on the arm once I have it.
