@lewm is dead right.
According to Peter Lederman, matching electronically usually means equalizing channel separation, which is a bad idea which can lead to a poor adjustment. So if you have a high end cartridge, with natural channel separation of say 37dB in one channel and 43dB in the other, you have to cant the stylus at a ridiculous angle to equalize.
Ask me how I know. My higher end Koetsu must have been at 10 degrees to equalize channel separation. Sounded terrible. Set optically and then by ear, and the cartridge sounds sublime. And it scarcely wears at all.
Assuming I've interpreted Lederman correctly and my observations are not too subjective. Anyway, YMMV.
