I think the proof is in the playback. I've come to learn that the less AS, the better. And, what I find to work for me is much less than what the tonearm manufacturer supplies for a AS weight. Too much AS is just as detrimental as too much VTF. It creates an over-damped situation that suppresses dynamics and speed. That said, you really have to apply AS if you get that tell-tale buzz in the right channel because then you do have a problem. If you don't hear it, then don't increase AS. I have many records that I can play with no AS at all. But I will no longer buy an arm that doesn't have AS.
