Tracking error or ??


I was listening to my Lyra Kleos last night and on one of the most dynamic records that i own ( and best sounding) an Analogue Production Sonny Rollins Way out West LP; I noticed on the second side, which is very dynamic and has some serious high frequency extension, that there seemed to be a little distortion (or over loading) that i suspect is coming from the cartridge. The Kleos is tracking at the recommended 1.8 grams and my arm is usually pretty immune to miss-tracking ( as it uses a liquid bearing). Anyone else experience the same kind of thing with the Lyra's? I wonder if a higher tracking weight might be the answer, even though Lyra recommends an exact 1.8 grams??

@daveyf , don't over think this, if it has just shown this on one recording and you have had good success other wise I would not be inclined to do any adjusting other than normal periodic adjustments as time wears on. FWIW I have enjoyed a few Lyra carts on uni pivot arms and still do. Enjoy the music
@mijostyn  Interesting that you believe the WTA is not a good arm. Yes, it does have characteristics of a uni pivot, but it also has zero bearing noise or 'pivot chatter'. I do think that there are certainly better arms out there, but would like to know why you think the 'WTA' arm is not good--and why you think it is worse than a uni pivot? 
My version is the 'black' arm with the Van Den Hul internal cabling.
Meanwhile, i am going to adjust the AS. 
Millercarbon is correct as lewm has indicated. 

I hate to be a sow's a-s but that is not a good arm for a Lyra and I think you should replace it when you get the opportunity. If you do not want to believe me just ask Johnathan Carr. He is a very up front guy and frequently visits this forum. In ways the Well Tempered arm is worse than a uni pivot arm.  
In a response the OP did incriminate the R channel. Increase AS is a good idea IMO.

Right is the outside of the groove. Could be not quite enough anti-skate. Skating forces increase with modulation. The most highly modulated sections cause more skating force drawing the arm more to the inside losing contact with the outside thus causing breakup. 

Skating also increases with VTF. If the breakup was both channels - and if you have room to increase- then VTF might help. But since it is only the outside (R) channel it is less likely to help and might possibly make it even worse. For sure you don't want more than whatever is the cart spec.
