This is not one where its even necessary to rely on "experts". You can prove it to yourself in a few brief moments simply by looking at the situation and doing something that may or may not come naturally: THINK about it!
Every pivoted arm swings in an arc. So the cartridge swings in an arc as well. Just look at it. Put an alignment template on the platter and look at it. Pretty obvious the tracking angle changes constantly as the arm arcs across the record.
Its never perfect, except at two "null" points. If you move the arm, change P2S a bit, all that happens is the null points shift a bit. Which you correct for with cartridge alignment when setting overhang. Who ever heard the sound shift and said, "Wow it sounded perfect there for a second, but now its gone! No, wait, its getting better again, now its gone!" As the arm swings from one null to another? No one. Ever! Therefore, logically, who is going to hear if they shift a millimeter one way or another? No one. Ever!
So why all the fuss? Good question. Drill your holes. Mount your arm. Just Do It.
As I have stated multiple times in this forum and only had agreement from the experts here, P-S is not an exacting spec, assuming a slotted headshell. Your cartridge and stylus have no idea about and don't give a crap about P-S so long as the stylus hits the desired null points.Exactly what I was going to say. Because it is correct. Biggest problem around here is the vast numbers of people unable to refrain from posting stuff that is just plain wrong, and then compounding their error by refusing to even consider correct information.
