AKG cartridges as explained by our respected member Nandric is another cartridge notorious for suspension problem. AKG took it back from the dealers/retailers and even destroyed the whole bunch of cartridges because of this issue (and their reputation) !
When someone recommend cartridges that are internationally renowned for serious technical issues (as suspension problems) I believe everything from such person must be ignored and can't be taken seriously if you don't want to loose money. None of us have personal relations with Van Den Hul and very few of us have unlimited amount of money to fix defective cartridges.
The problem with the most expensive Technics cartridges, even if they are sealed NOS, is rubber damper, I don't know any other cartridge (and I owned so many) with the same problem! And I learned this myself buying those Technics cartridges over the years. This is clearly the worst vintage cartridge ever, because of this issue with softened suspension. But it was so hardly promoted on audiogon so people think it's perfect cartridge, but it's not !!! If you read caferully between the lines in that old MM thread, those working samples were refurbished by VdH (the most expensive expensive service on the planet earth). On some other samples the whole cantilever/damper was transplanted from another cartridges like Nagaoka by Axel in Germany.
I know who sold refurbished cartridges without even warning his customers about third party parts (fake cantilever) inside these cartridges.This is disgusting! I even bought such cartridges myself few times (I was a victim) ... Some other audiogon members recently told me about similar issues privately (when a seller did not tell anything about refurbishing and sold it as original, you'd better not know who was the seller).
There is a huge difference between an ORIGINAL working cartridge and REFURBISHED cartridge. Especially when it comes to very special and very expensive vintage MM cartridges.
