Cartridge for Symphonic music .

GLANZ MFG-51L w/ tapered aluminium cantilever and GLANZ MFG-610LX w/ boron cantilever, latter hard to find thou... both outperform certain AT top dogs on, say Telarc Digital cannons. Can´t be bad for the most complicated and demanded music recorded on vinyl right ?

^ Everything is a final statement. Well, I doubt about that Ortofon, I´ve read on other forums like Steve Hoffman Music that some people have had sibilant issues with it. And I ain´t no Shibata fan boy. Because I once had an Audio-Technica 20SLa and even with a new replacement stylus SS (w/ Shibata stylus) it was somewhat sibilant no matter how it was adjusted so I had to sell it as I can´t stand sibilant David Byron not to mention Greg Lake. Very annoying. Instead I recommend a MI like Nagaoka´s best models.
Btw, are they truly Moving Iron cartridges, Schubert ? They always are advertised as MM nowadays.

Yes it has a Line Contact stylus and boron cantilever:

Vintage Audio-Technica carts 20SLa and 20SS had/have Shibata stylus.

Indeed the ART9 is superlative performer reviewed by so many, please read the threads about here on A`gon for start and continue on other forums.
As for my bad experience with my SLa/SS sample, it was evident with different pressings from different origins (countries). I´m positive that my new SS stylus (from Needle Doctor if my memory serves me right) was somewhat defective, as those replacement styli are mass production after all. And the cantilever was a few degrees off-center already from new so one can make some conclusions. ( However, a slightly off-centered  cantilever is not a problem as cart´s body can be adjusted so that stylus itself will track right as is meant to).  
I blame mass production and poor quality control, not Shibata per se.
