Is VTA and SRA the same thing?

One thing to keep in mind- the SRA at 92 degrees is an average. In reality the mastering engineer didn’t set the cutter stylus that way. He set it up so it would cut a silent groove. The cutter stylus only goes about 10 hours, then you have to remove the cutter head and replace the stylus. At that point, you have to installed the head and get it aligned and calibrated, and then start fiddling with the height of the cutter and the stylus temperature until you get something that works.


The result is every LP is slightly different. Fun huh?

Thank you for all the responses gents. I understand a lot more.
Second question: 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?

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.

I understood what you said, that is why I said “very closed to 92 degree”
