Suggestions for tonearm for a Clearaudio Champion

I was hoping a member has experience with the Clearaudio Champion II that I recently purchased. What cartridge and tonearm would be best for this. I have a Audio Research LS-3 with an Oddyssey Stratos and Dynaudio Focus 220's. I also have no phono section on my pre so maybe a suggestion for a phono pre amp
Thanks,
Dan
