Dear @dangcaonguyen : """
I understand a lot more...... Can we trust on the cartridge manufacture on the 92 degree SRA? I mean, if we can set the top of the cartridge perfectly parallel to the platter, then we can get very close to 92 degree? """
Certainly that you are not understanding very well the overall subject through all the information posted here.
You can trust in nothing but your ears on the subject because: each cartridge manufacturer puts/attach the stylus tip to the cantilever in different angle ( around 19°-23°. ), all LP are cutted different ( read atmasphere posts. ), you own 120gr., 140 gr., 180 gr., 200 gr., etc LP's, all LP's comes with surface waves, etc, etc.
Your VTA/SRA set up works as you want it only in that LP and not exactly the same with other LPs.
