in current mode I would think almost any quality MC cartridge would be a great match. My best guess would be that lower impedance cartridges would be slightly superior as the circuit sees the MC cartridge as a near short electrically. But then again lower impedance may just equate to higher gain. You should try and contact Norman Luebke directly. luebke*at*aqvox*dot*de what is "best" is purely subjective based on your own sonic priorities.
