Dear vocalpoint, You might be interested to read the following post from Vinyl Asylum addressing just the question you are raising, whether you knew it or not:

The post supports my recollection that Stevenson and Technics are different. If they ARE different, that may account for the fact that you need to twist your cartridge a bit in the headshell in order to align it with the protractor. You might ask Yip what geometry he uses for Technics tts. I'd be interested to know the outcome. I would repeat however that I doubt this accounts for the fact that you are underwhelmed with your results.
