VPI Uni-Pivit Tone Arms

@testpilot, the ears as far as I know are only adjustable on the 3D arms but being they are rubbing that would indicate to me that that is what he is dealing with and needs to screw these all the way in and adjust the azimuth as close as possible with the dropped counter weight and only fine tune with the side weights. A Soundsmith Counter intuitive might help also, I know they work well for me. Enjoy the music.

VPI now makes a Gimbal bearing tonearm. About time.
The unipivot topology came about because it is a cheap easy way to make a tonearm. Don't have to by expensive bearings and worry about tolerances but there is trouble in paradise. To many degrees of freedom. A tonearm should only be able to move up or down and side to side. It should be absolutely rigid in all other planes. Records are not flat. Any change in altitude is going to subject the arm to torque because the arm is offset which is going to change azimuth. Graham tried to fix this using a magnetic field to hold the arm steady and it works if you want to spend ridiculous money on an arm. I would rather get a 4 point. Much less expensive, better sounding and more suitable for a wider range of cartridges. 
VPI has finally come out with a turntable I could consider, the new Direct Drive with the gimbal pivoted tonearm. If they could figure how to suspend it like a SOTA it might even be perfect.

@mijostyn, I love all the unipivot arms I have owned and still own the 3D Classic arm and a JMW9, simple works best for me and I have no issue with milking the very best from these arms. Are there better? I am sure there are but to what exspense? I do agree with you on the point of no movement in the vertical plane thats why I would not consider the unipivot without a center clamp, BDR/Stillpoint and the periferal ring. Still wondering if this is a 3D or metal arm the OP is having this issue with.

He did not say but only the arm wand is different. The bearing assembly is the same. 
Sure tooblue you can make them work. Clamps help as you suggest. Staying with more compliant cartridges also helps. Less leverage on the arm. Asymmetrical counterbalance weights also help. But, theoretically at least a captured bearing would be best. How does this effect sound. Know way to know from here. More than likely it would be hard to hear difference. I'm sure Michael Fremer could hear the difference. His hearing is better than mine:)

I was addressing the rubbing of the outer weights on what I believe would be the VTA tower as the only thing short of a bent part or drastically maligned setup for this to rub as the 3D weights do screw in and out. I just looked at his system page and see it is a metal arm.
