AT OC9/II vs AT OC9/III

Does anyone remember the OC-9? The first one, with no Roman numerals? I bought one 25 years ago when it was the latest "greatest bargain ever", and kept it for future use. It's still NOS. Any comments on what I can expect to hear, not in comparison to its successors, but as a cartridge in general? The tonearm(s) I'll use are good matches and shouldn't be a factor, and the suspension seems fine.

What OP should really get is the ART9. 

Many years ago I spoke with the US Importer (I believe) about the difference between the two and (if I recall correctly) he told me the ONLY difference was the way the stylus was fixed to the cantilever. Consequently, he said, there was no difference in the SQ. I'm not sure whether or how this would impact the compliance difference noted in the thread (I did not look the compliance stats up to compare) but that is my recollection. FWIW, I ran an OC9MLII for a number of years and liked it very much on my VPI Scout. I also ran the ART9 which is superb--much better than the OC9MLII (and much more money as well).

dodgealum - Are you still running the ART9?

Bill FWIW, soundsmith adjusted the suspension on my original Clavis  and did level 2 rebuilds of two different Helikon SL carts proved to be better, by my taste, than the originals. I will get back to you after I have broken in the new AT ART9 cart (purchased from 2Juki for $860.00) after broken in. Thanks again.
