I'm not dutch.

Looking at the Clearaudio site there is no figure for effective mass on the Satisfy model. A similar looking current model lists at 9gm which is low-medium and looking at the Satisfy it certainly won't be high. I'd say that it appears less than ideal for a Supex without some mass loading - you need around another 5g or so at the headshell as a minimum.

The modern Goldring models are excellent and sit around 18-20cu in compliance. The Supex was around 8cu IIRC and as Dave says some were lower.
