Dear Syntax,
Thank you for your nice photos.
It is clear that for ALL of my records, (your first photo) the prefered TONEARM'S ALIGNMENT is the Loefgren B.
The problem that I'm still have, is that I can't indentify those particular points on the TONEARM'S GEOMETRY, that dictates to a specialised/individual/unique alignment !
Not to be confused with the alignments of the B,L,S, IEC or DIN, (that depended by the way the LPs were printed on vinyl).
I'm really sorry that I'm posting about this again, but I've just figured a possible misunderstanding might occur about my quest.
What I mean is : When you look a tonearm, how can you see those points that require a modification in it's geometry ?
Is that all about setting new null points ?
I don't expect an answer, I'm posting this just to clarify.
Thanks again.
