I am not familiar with your arm and cartridge but from the picture i can understand that the notched rod is a thumb screw, what happens if you unscrew it a bit (making sure it still remains firm). That would increase the AS force a bit.
Normally AS force should be much less than tracking weight and is not implemented mechanically the same way on differently designed arms.
Applying more AS is like adding more tracking force but to one channel only so your sound will be more closed in amongst others.
Here comes your observation that on Analogue test Lp with limited AS the sound is equal to your ears, so you do not need more of it.
