@mijostyn Simon will thank you for that endorsement.
He is aware of the VTA issue. He provides very fine height adjustment if necessary on the fly with a large diameter knurled wheel operating on the arm pillar by a high geared tensioned worm and screw. Using a parallel lines protractor against the lower flat surface of the arm, its arm height can be set very quickly and precisely for each record.
In fact the low effective mass of the arm works in its favour, particularly with a low mass cartridge. Tracking is very secure.
Yes the working length of the arm is unusually short. Simon didn't design if for use with off-centre records or for warped records. In fact because of its low mass this arm tracks warped records that no other arm will track - they just get thrown in the air. If you find this of value. But this also demonstrates the tracking security of this set-up.
if you tap any turntable hard enough the cantilever will flex under the force applied. But, all other things being equal the effect will be less than in the case of 9 inch pivoted arm with much more mass and therefore side force. And from his S7 on, Simon didn't believe in hi-mass as the best approach to isolation. I don't tap my turntable while it is playing.
Thank you, but I am not in need of parallel tracking arm recommendations. I believe the Aeroarm is the best design. Period.
