Tracking error or ??

@grk   I did as suggested above and increased the Anti Skate a little. This seems to have solved the problem, although I still need to listen further to some of the more 'dynamic' passages. 
Agreed, there are always folks who will naysay any product, even with absolutely zero knowledge or experience with it. Not sure why this is a thing? 

It just is. Just like I knew it was anti-skating, others know its something they know nothing about. One of the mysteries of the universe. 

Davyf, AJ considered The Work of Art to be his magnum opus and I have heard one. AJ tried to get me to buy it!
Now, as for your complete and total misunderstanding of the Kuzma 4 Point arm. They are in no way, shape or form similar to a unipivot. The Kuzma uses needle bearings, four of them that produce a solid low friction 2 axis bearing system. The vertical bearing is exactly like what Origin Live does in its better arms. It is the horizontal bearing that is special. The vertical bearing platform hangs from needle #3 which engages the top of the center post. Then in front of the post is a slot that engages needle #4. Since the weight of the tonearm engages the platform in front of the post needle #4 is force back into that slot. Needle #4 prevents any torsional instability. I can only move through an arc of 70 degrees which is more than enough to play a record. There are breakdown pictures of the 4 point bearing if you are having trouble envisioning it. It is not easy to describe. I have installed 4 Point 9's on two Sotas with excellent results and it will do great on an LP 12. I would be very surprised if you did not immediately notice an improvement. 

grk, there's that listening thing again. You can not trust any single individual's listening skills. Regardless of the way you think that arm sounds it is a more defective design than even air bearing straight line trackers. Forget about what your ears are telling you. Get a better arm and they will be even happier. Tonearms are very simple devices. There job is to hold the cartridge perfectly rigidly except in two directions, up and down, side to side. If it does not it is automatically disqualified from being a decent tonearm. Even the possibility of movement in another direction is not acceptable. After this are the finer points of good tonearm design, geometry, bearing design, anti skating, resonance characteristics and such. There is certainly room for creativity and original thinking. Both Frank Kuzma and Frank Schroder are great examples and both have designed some klunkers. 

Never be ashamed of buying a bad piece of equipment. I have had my fair share. That is how you learn. I was lucky early on getting a lot of exposure working in the business. But, I let myself get waltzed into some pretty stupid stuff the highlight of which was a tonearm. The Transcriptors Vestigial Tonearm a very strong contender for the worst tonearm ever made.

@mijostyn I think you are confusing AJ’s work a little. He did bring out his "The Work of Art’ table as his top model..prior to the Transcendence.

As to my understanding of the 4 Point arm, I feel your post was quite supercilious and telling. BTW, you might want to get ’there’ and ’their’ in order...for instance it would be ’their job is to hold the cartridge’...
oh, sorry that is just about as supercilious....lol.

Sorry, the Kuzma 4point 9 will not work well on an LP12, simply too heavy for the little fruit boxes suspension requirements.

The easiest way to conceptualize the 4point bearing is as two knife edges (one for horizontal movement, one for vertical movement) with the center sections removed. Since there are only two points left as contacts at the extreme outsides of the knife-edge, any manufacturing unevenness between the mating surfaces doesn't matter.

And since the pre-loading (mating pressure) is only applied from one side, the loading can be increased without being overly concerned about cracking the bearing balls or thrust plates on the opposing side.

The result is a zero-clearance bearing, which similarly to a unipivot, doesn't have any loose or lightly-loaded components to make noise or resonate. But unlike a unipivot, since the horizontal motion and vertical motion are stabilized across the full width / length of the centerless knife-edges, there is no azimuth floppiness.

The 4points are clever designs that perform quite well.

@daveyf, it is reassuring to know that revisiting the anti-skating settings has brought the Kleos' tracking performance to where it should be.

Regarding the current-generation Well-Tempered tonearms, there is much to like about them. However, granularity of anti-skating and azimuth adjustments could stand some refinements (smile).
