Hi Don,
I hope Kansui (a bit higher compliance vs Shilabe) goes well with Graham.
I listened to Kansui with Kuzma 4p tonearm and Clearaudio (dont exactly remember the model perhaps Innovation), it was marvellous. I also listened to PP1000 with Clearaudio Linear Tracking tonearm (either tt2 or tt3). So I can not directly compare both cartridges since tonearms are different. Having said, Kuzma+Kansui was more musical, the soundstage and focusing more precise to my ears while PP1000+Clearaudio more on the analytical side, more detail, a bit aggressive on highs while Kansui+Kuzma's highs texture was better. The mids, no question, Kansui side clearly outperformed. Both cartridges with their tonearms had good bass definition. If I did not order Kansui before that listening test, I would order without any hesitation afterwards. By the way, my friend who owns them likes them almost equally, so my feedback is just one man information.
