Steve:
One thing to realize is that you will have to alter the loading once you put the step-up in line. The Consonance seems to have 20dB and 17dB taps, which refer to the amount of gain you can get. Assuming you want to stick to around 100 ohms loading and want to use the 20dB (i.e. the higher gain) taps, then by my calculations you will need a pair of 12.7k resistors. I'll order them this week for you. If you want 150 ohm loading, then you'll need a pair of 22k resistors, ironically the exact same value I purchased for your other cartridge, so I'll have these on hand as well for you.
