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.

Harry already has modified a few arms....Fremer, his own, et al.......just order the Prime with the dual pivot arm. Its not surgery....Harry says he’s working on a way to do it at home with no tools.  By the way....Lyras and Ortofons work great with the 3D...

When Harry changed from 12.6 to 12.7 he brought back adjustable fluid damping. IMHE it was a big improvement and continues to be useful. What I hear contradicts @stringreen 's comment above about closing in the sound and eliminating air. That's what happens when it's OVER-damped, not damped. If that is your result, just dip a Qtip or two into the fluid to absorb a bit of oil and you should be good to go. Cheers,

VPI metal arms have a damping adjustment.....VPI 3D arms are designed without one.  There is a reason a simple thing like a cup for fluid was eliminated.  I could guess, but then again.....
