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.

Fremer’s mini review notes "no audible improvement", just a "psychological" feeling of more stability, before playing in the groove.

What about increased friction screwing with anti-skate?

Nothing of significance here IMO!

I am wondering why this mod with this arm, the 3D arm? As some of you know I have had several of these arm wands and have had issues with the arm twisting slightly under normal conditions, ever so slight but have gotten into the habit of checking and adjusting before each listening session.

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.
