Could someone suggest a decent audiophile cartrige for a Technics dj TT?

+1 Nagaoka MP 110. I've tried all  the usual  suspects and there is no better buy in audio .
Plus it takes a  MP 150 stylus which will give any sane person all they need .

@addyson815 You can use hi-fi test record to measure the actual resonance frequency of your tonearm and cartridge. When you are using low compliance cartridge on lightweight tonearm the resonance frequency is way out of the desirable range. Simply read here. Not sure if you ever tried your Denon 103 on a proper high mass arm, maybe you can explain why you prefer lightweight or mid mass tonearms for a cartridge with compliance as low as 5cu @ 100Hz?  

We use a Grado Gold on our older Technics SL1200 which we use in our mastering lab to listen to cuts we've made on the lathe. I've yet to see it mistrack.

+1 Grado
Perfect match for the 12 gram arm on the Technics!

Another Grado user here (on a KAB SL1210 M5G w/fluid damper).
Grado Black stylus replaced w/8MZ .
Tracks well and sounds pretty good too.
