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??

In a response the OP did incriminate the R channel. Increase AS is a good idea IMO.
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.  
@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.
