Dear @daveyf  : ""   Lyra recommends an exact 1.8 grams  ""

Not really, JC spec is exactly 1.72 grs. :

   I think that you need to reset/check the overall cartridge/tonearms set up along the VTF spec, maximum VTF is 1.75 grms.

Btw, I can't know the effect over time in the cartridge suspension using 1.8 instead 1.72 . It could be a good idea to send an email to JC.

DaveyF, pivot "chatter" is an illusion created by people who are trying to make excuses for unipivot arms. Bearings in proper adjustment are preloaded. There is no clearance at all and no room for "chatter" 
The Well Tempered arm is an interesting design, clever to a degree but like the unipivot basically flawed. A proper pivoted arm has two degrees of freedom vertical and horizontal. A unipivot has 3 degrees as it is free in torsion. The Well Tempered arm has 4 degrees as it adds torsion and longitudinal motion. Each free degree has a resonance associated with it.
The Well Tempered arm tries to deal with this by adding mass and fluid damping. These are crutches for flawed design. A properly matched cartridge tonearm pair should never require damping or added mass which adds inertia. It takes energy to move a tonearm through damping. It is like adding more friction and energy to overcome inertia. This energy comes from the record groove and can be seen on an oscilloscope as unnecessary cantilever motion. The cantilever moves because the tonearm does not, producing low frequency garbage, distorting the frequencies above. In really bad set ups you can hear it as a warble.

@tooblue, karl_desch is moving from a unipivot to a two axis arm with a Lyra cartridge. Follow what he has to say about it. it. https://forum.audiogon.com/discussions/kuzma-4points-and-lyra-carts

@mijostyn, thanks for the lead but will just spend that time listening to a very good resolving system and then thank my keen ears for leading me there. Enjoy the music

@mijostyn  I'm not following you with regards to your point about the WTA having added mass?The WTA is one of the lightest tonearms around, so light that I can use it with no issues even on my LP12, without disturbing its ultra sensitive suspension. I also don't follow you with your point about the longitudinal resonance...how is this? 

I do agree that the WTA has a lot of design issues, along with its brilliance. One of my biggest issues with it is that none of the adjustments are that precise, along with a propensity for these adjustments to not stay through time. The azimuth adjustment is a good example of this. OTOH, the fact that the arm is well damped does help with a number of cartridges that put a lot of energy into the arm, ala the Lyra's. Lastly, isn't the Kuzma 4 point still basically a uni pivot design?

to the OP, while i have a Lyra on a Triplaner, i have heard some fantastic music come from systems using the WTL tables and arms, notably the Amadeus .Did your tweak solve the issue ?
