Thanks Dominic - I am a bit confused now as I would say the cantilever IS deflecting by a 'noticeable' amount eg I can notice a definite change of angle when the cartridge is lowered onto the record. But this is a brand new cart and certainly has never been dropped heavily onto a record, I always use the lever to lower the cart.
Really not sure now if I have caused some damage with the extra 1g weight?
I seem to remember that on the DV20X carts the cantilever should be quite stiff eg when lowered onto the record it should not change angle at all.
Can anyone else (DV20X owners) confirm this?
