@speakermaster:  Regarding ..."the vinyl pressings can have distortion on highly modulated peaks that are not there on others especially at the end of the record side."

I find this interesting and would like to learn more about this.  Out of curiosity, could you share which cartridge and tonearm you are using when this happens?

I ask because I wonder if when this happens if it has anything to do with which type of stylus profile the cartridge has, or if it has something to do with the type of tonearm... gimbal or unipivot, etc.

When this happens... is the distortion just in the right channel or is it in both channels equally?

I wonder if it is groove wear or does it happen on brand new vinyl as well?

Best wishes,
Don

@daveyf, The problem is that friction pulling the tonearm along it's long axis is not constant but varies depending on groove velocity (modulation). Thus there is going to be a tendency for the arm to move in that direction. How much it does would depend on VTF, the mass of the cartridge and the velocity. Does it move at all? I do not know. But it can if enough force is applied and that is enough for me. 
I talked with AJ on several occasions. In his mind the hanging suspension was vastly superior. You see this in the Work of Art and Inspiration turntables. I have no idea what happened with the Transcendence. It is not in keeping with AJ's design philosophy in a number of ways. He also would never have stuck his name on the turntable. https://robbreport.com/gear/audio/slideshow/10-design-minded-turntables-clearaudio-vpi-eg17/aj-conti...

@mijostyn  I think you must be confused. I believe that AJ considered the Transcendence as his Magnum Opus!  If you ever get a chance to hear this turntable, i believe you will understand why.

As to the WTA, I have heard absolutely no issues with the arm whatsoever in regards to its ability ( or lack thereof) to move in the longitudinal axis. The forces required to make it do so just don't seem to be applicable to the design. 

I think the under biasing idea is the answer but check that the cantilever is still in line. I had a similar symptom after a year of heavy lockdown use and found the cantilever was off skewed towards the outside of the disc even when not playing, though this was only visible with the cartridge, an SPU Royal N, removed from the arm.
Nice to see a WT arm on a Linn by the way. I came close to buying a Versalex but it’s feet were a bit too close to the edge of my Fraim.

@yeti42   The Kleos has a cantilever that can easily be impacted by wrong A-S. I have to take a listen to the modification that I did to the A-S tonight, but what i added was a very small amount, as too much and the cantilever will skew. The WT arm is a good one, however, I think it is the weak link in my system. Problem is that the LP12 is very limited as to what arm will work and so far none of the choices are that great.
