I've been reading a lot about cartridge alignment.
Most of the discussions about the differences between Baerwald/Lofgren A, Lofgren B and Stevenson seem to indicate that all three can be successfully implemented without regard for the tonearm being used.
The tonearms that I own have their vertical bearings "canted" in a way that will maintain azimuth as the tonearm moves in the vertical.
If a cartridge alignment, different than what the tonearm was designed for, is used the cartridge will have to be "twisted" in the head shell. This will cause a shift in the azimuth as the tonearm rides up and down while playing anything other than a perfectly flat record.
Furthermore, every time the tonearm is lower or raised at the back to set/change the SRA, the azimuth will have to be reset.
And further again, if a thin record is played the azimuth will be different than when a thick record is played.
My conclusion is that one needs to know (or figure out) what alignment the tonearm was designed for and stick with that. Always use the alignment that places the cartridge (cantilever) straight in line with the head shell.
