Best Cartridge for VPI Aries orig + JMW 10.5 ?

I have a VPI Aries (original version) and JMW 10.5. They feed an EAR 834p phono stage, mccormack map-1 preamp, rotel 1095 amp, and vienna acoustics beethoven speakers (which are a bit "warm" sounding). I listen to mostly bluegrass, followed by classic rock and jazz. What is the best choice of cartridge at $1500 or less? (any views on the Sumiko Celebration in this set up?) Any thoughts welcomed as I am a bit new at this. (ps. will one day move to all tubes, but likely a few years off).
