I've mounted cartridges with alignment done via different tools over the years: dbSystems, WallyTractor, Feickert, UNI-Protractor (best I've used.) One goal is to get the stylus tip on the null-point(s), another goal is get the cantilever properly aligned with the 'engine'. For moving coil,
that could be coil(s) on the end of the cantilever aligned with internal magnet(s). Granted all thus presumes a well made cartridge.
Doing this I played records and listened. Sometimes I'll put the 'table back on my bench and check the alignment. Sometimes I find I can do a better job aligning the cantilever. Invariably when I do that and listen again I experience better sound. The degree of difference may not be huge but I find it is audible and worth the second alignment.
Null point(s) alignment can change with tracking weight, with VTA adjustment, and with cartridge break-in. I usually check alignment after, say, 300 hrs of initial use and when adjustment is required I find sometimes sound improves.
