I tried the nickel test (assuming a nickel weighs 5 gr.) and my scale weighs it at 4.9gr. The owners manual for my ZYX Yatra has a tracking range of 1.7gr.-2.5gr. with a recommended tracking force of 2gr. If I assume my scales weigh light by .1gr. I find that records sound their best at 1.7gr. (scale set at 1.8gr.) I know this is on the very light side of the scale, but there is no mistracking and cymbals both shimmer more and have more weight to them at 1.7gr. At the recommeded 2gr. everything sounds kind of flat and dead sounding. I have played with the VTA at the 2gr. setting, but it still does not sound as good as at the 1.7gr. VTF. By the way, I am able to adjust VTA while playing a record (which is nice).
So, I think I am happier with the sound when I fine tune by using my ear and not the gauge.
