Classe DR-5 Pre-Amp

I have the DR-5 stock pre-amp. I would like to get feedback from all using this pre-amp regarding the phono cartridges being used expecially MC cartridges. I have no idea which might work best with this unit. I will eventually be using my Original Rock Turntable with the EXcalibur arm. In addition I have the following:

1. Threshold S/300
2. Mirage OM-9 floor standing speakiers (upgrade to Mag 1.6
3. Parasound Belt Drive CD Transport
4. Inexpensive DAC for now
5. Sumiko MM cartridge

Thanks much for all input and advice.
