Should I try a MC cartridge and phono pre?

MC cartridge picks up much less EM noise than MM, has wider freequency bandwidth and can improve ANY turntable setup. Going with high-output version of MC cartridge is also benefit to MM in many cases.

Francisco,
In general the quartz digital drive has the least amount of EM noise compared to AC or idler-wheel DC motors. The only consern in DD tables is influence of the power supply EM noise that very often located inside the TT chassis and somewhat transfered vibration of the digital quartz clock to the platter. Depending on the design quality, DD table can even be more quiet than idler-wheel or AC- belt-driven ones. As I previousely mentioned, if you have MM and MC cartridge with the same output voltage, MC cartridge will pick up substantiall less EM noise and will have wider freequency bandwidth in ALL cases, thus will improve ANY turntable.
