You may need to consider both the phono stage gain and the preamplifier gain. I am using a Karat 17D3 and DV75 Mk. II set for 63 db of gain going into a McCormack TLC-1 using the non-buffered output, which has no gain. I have to set the volume on the TLC-1 just a bit higher than I do for the CD player.
This makes me think that under many circumstances that this would be enough total gain. I don't know if the Monolithic, as good as it is, has a good combination of impedance and capacitance matching for the Karat 17D3. As another poster mentioned, the match of this cartridge with the DV75 Mk. II is designed to be right.
In fact, the DV75 Mk. II works better here than the combination of a Dynavector DV/6Z stepup transformer and a McCormack EF-1 phono stage in regard to overall sound quality.
