Tom, all of the cartridges I ran into the JLTI were LOMC with outputs from 0.25mV to 0.5mV. Unless you go all the way down to below 0.25mV or want to use a passive preamp you will be fine with the MC gain.
Also the specs state 55dB gain for the JLTI. Using the same loading the JLTI played louder than the Dynavector P75II at the 60dB setting or the Ph.D. at 60dB. Seems like the specs are quite a bit understated and the actual gain of the JLTI is around 60-62dB.
