If I get a cart. w/ shibata, micro ridge, line contact etc and can’t adjust for VTA is there still a difference between them and an eliptical/ conical?. Grace 707 arm.
First of all you have to check do you really need to adjust VTA, then (if you need) you can add cartridge spacer between headshell and cartrisdge, you can also change the mat (different thickness) so i think you can adjust more or less. I’m not familiar with Grace tonearms, you can swap it with excellent and inexpensive Denon DA-401 tonearm with adjustable VTA.
It is true that conical tip is less sensitive to errors in adjustment, but some people overestimate a problem with adjustment when it comes to advanced profiles.
