1) The Cartridge is very sensitive to capacitive loading. Some experimentation with it will be necessary to get the best match to your system. I ended up with 51 kOhm resistive Load and 120 pf capacitive load (plus the Tonearm cabling - probably another 50 pf or so).
2) The cartridge is a little more than usual sensitive to VTA (Vertical Tracking Angle) adjustments (for a Moving Magnet Cartridge), so experimentation is on order.
For this setup, there is not adjustability to cabling or capacitance in the phono preamp, and the tonearm has no VTA adjustment. Perhaps there is a cartridge that is less sensitive to these non-adjustable features?
