2nd pivot for VPI 3D

I think it would be useful of reviewers of the 2nd pivot let us know which cartridge is being used for evalualtion.  I suspect that the pivot would be more beneficial to low compliance (stiff) cartridges rather than high compliance ones.

That is a good point. My cartridge upon which these comments are made was an Ortofon 2M Mono SE, which is based on the 2M Black.  Lateral compliance is 22 micro meters/mN.  The arm is a metal VPI JMW 10, Series 3.  I have another kit on order for my 3D arm and will probably start with the 2M Black when it arrives because of the similarity of those 2 cartridges.  I am also eager to mount my favorite cartridge, a Per Windfeld, in the dual pivot modified 3D arm.  Later I might try either a Shure V15 or a Stanton 881 or both, who knows?  I have a lot of cartridges.

I'm using a black wrapped 10.5"arm with an Ortofon Cadenza Red.  Next install will be on a 10.5 3D arm with a Cadenza Black. I wanted to start with my lessor cart/arm then work my way up. 

I've been reading everything I could about this mod....it seems to be universally accepted as a pretty significant improvement.   I have a 3D with a Winfield installed, and now am a bit concerned about the question that low compliance cartridges are a better match.   I have never heard that before.  I haven't bought it yet...not because of the cost, but it would be disturbing the setup I now have which sounds good to me.  I'll continue reading these posts

It is easy to back the second pivot screw out just enough to lift it off of the glide plate.  Doing so is identical to removing the kit.  This makes it very easy to compare the effect with and without the second pivot.  The instructions suggest starting with the minimum amount of pressure necessary to keep the point of the second pivot in contact with the glide plate throughout the entire arc of the arm.  Then increase pressure in small increments to compare the sound.  Increasing the pressure results in sound improvement up to a point, then it falls off.  With the 3D arm making this pressure adjustment is very easy to do by adjusting the azimuth weight out on the side with the second pivot.  A Counterintuitive is also an easy way to adjust the pressure of the set screw on the plate for arms that lack the adjustable azimuth weights.  You are doing nothing that can't be undone, practically instantly, and the mod will undoubtedly improve the sound of your Windfeld.
