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