I owned the Simon Yorke S9 and once mounted a Pertinax wand Schroeder Reference to it. In my opinion, the original tonearm gives a better match, provided you use better cables for the Simon Yorke tonearm. I used a solid core cabling mounted at the outside of the tonearm wand of the Simon Yorke tonearm going in one run from cartridge to preamp.
