Don't take this wrong, that I don't appreciate any and all post and answers, but I have to ask, why haven't you asked Mr. Berdan? Not only is he maybe the most knowlegdeable person ever to deal with a turntable, but when I was lucky enough to live in the L.A. area where his services were available to me, I found that evan though he was a busy man, he was always willing and glad to answer any question I had, and a real nice guy as well.
And you're lucky again, (you may already know), he makes his living setting up, adjusting, altering, and modifying turntables. He is a hero of mine.
Does he still have the display of all those cartidges? It looks like a historical record of cartridge development, in real life! Evan the expensive ones! I'm glad to hear that he is still there.
