Lamm phono stage LP2.1 Deluxe with low output ZYX MC cart

Does anyone have experience with using the Lamm phono stage with a low output MC cart with .25mV output? I will be using the Lamm LL2.1 Deluxe preamp. Some reviews caution using a MC with such low output, while other reviewers seem to suggest no problems. I would rather not get a SUT. 

Thoughts?

This is not extremely low output, shouldn't be a problem for a LOMC phono stage. Owned a few ZYX carts and it was fine. A dedicated ZYX active headamp improved the sound, look for ZYX CPP-1 mkII pre-preamp instead of a SUT.

You can order the LP2.1 Deluxe with 31dB of MC gain (versus the default of 20dB). This configuration is ideal for cartridges with low (<= 5) internal impedance, which most ZYXs appear to be.

The LP2.1 already has SUTs, internal Jensens I believe with fixed 400 ohm loading. I’d be more concerned about that matching well because doesn’t ZYX like the typical Japanese 100 ohm load?

The ZYX has an internal Impedance: 4.0 Ω (8.0 Ω) Load Impedance: > 100Ω.
The LP2 has set configuration for MM and MC. 47k input impedance which apparently results in nominal value of about 430 ohms load.
Thanks
