Help me understand cartridge alignment


I have a Ortofon Bokrand AB309 arm and I'm using a Royal N cartridge set up using Baewald geometry using the Feickert protractor. It's sounds awesome. I also have an Ortofon SL15 and I put it a cartridge and weighted it so I can swap it out for the Royal N any time without adjustment. The thing is, I don't have the right headshell for the SL15 yet so it can only line up like 5MM short on the Feickert. It also sounds great. So why is this? It doesn't line up with Stevenson or Lofgren. It's just off the grid and yet it's fine. I don't understand.

A 2.2mm shift in the mounting hole dropped the SPU I have right into place for Baerwald geometry. While I thought the sound was great with it off by the 2.2MM (I know I said 5 but I was wrong in the end) it turns out that it's better properly aligned.

I didn't really notice because even improperly aligned, the new 401 w/SPU is so much better than my old setup!

@lewm  , no I'm not was wrong because that opinion you had it just when you set up your Dyna 505 where I questioned you not to use Stevenson but Löfgren and you said no because all that bla, bla, bla.

I was not wrong, things are that you have short memory and this issue is not the first time coming.

Raul, in that interaction you were per usual arguing the superiority of Baerwald vs Stevenson. We were not discussing the importance of very accurate alignment. Perhaps it is you who have the faulty memory. Also back then I was reporting a problem that arose when I used Baerwald with my 505, which requires twisting the cartridge with respect to the headshell. Again, that had nothing to do with the anal approach to alignment. I won’t rehash the whole issue here.

Exactly, my memory is not faulty and here you are discussing about  that offset angle and TD not accuracy.
