I'm familiar w/ the Morch (but not the OL; what a quandary:)) It's a very good arm and relatively easy to set up. The azimuth, angle, etc are correctly set, so no problems (unless the previous owner has been playing with this; if so, Tom, if you can convince him, could probably solve the issue magnificently...).
I used the arm with a Clearaudio Accurate & Discovery. It's on the neutral side of neutral (to coin a bad phrase), tracking is very good & resulting "speed" effect is excellent. Musical presentation is very open, mids are liquid (not harsh/ analytical) and the upper end extension obtained was at par (if not better) than with a more expensive arm. We didn't notice resonance issues and the bass was very clear and tight (maybe lacking ultimate extension?). Note that listen to classical music & use large orchestral passages to "audition" arms & cartridges.
I THINK a Morch would like the construction concept of the Teres; it felt very well in a Clearaudio TT, a big Project and a S. Yorke.
BUT, I've never used a 901. Maybe Tom can extrapolate because $800 for the Morch +cable looks like excellent value.
BTW, this is an exotic analogue rig you're setting up!
