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?
