VPI 3-D tonearm

Harry has said that he's installed almost every cartridge into the 3D with success. If it were I, I would call VPI with your question, but having many arms, none is as much as a "no arm" than is the 3D

I have use a Koetsu Azule on a 12-inch 3D arm. It sounds amazing. Prior to that, I had to use Damping fluid in a 12-inch metal VPI arm to get it to sound right.

I have a 3D arm on my Aries 3 with an Ortofon Cadenza Black - mates very well.

I have a Lyra Titan-i on my 10" 3D tonearm- sounds great!

It is ESSENTIAL to know the effective mass for proper cartridge matching!

Why is VPI hiding this spec??? What are they afraid of???

I guess they do not believe in science, or think it will work optimally with "any" cartridge. LOL!

By the way, they have never listed the effective mass of any arm in the past.
