Running a LOMC in MM setting?

Hi! I bought a Gold Note Ph 10 for my system, what is the following:

VPI Classic 1 TT, Ikeda 9TT LOMC cartridge, Gold Note PH 10 connected with balanced xlr cable to a pair of Dynaudio BM5 mkIII active studio monitors. I am using the Dynaudio`s dedicated volume box, connected directly to the studio monitors.

The problem is the following:
When I am using MC setting in the PH 10, the sound is just terrible. I set up everything accordingly to the cartridge, and it sounds really bad. BUT, I have tried the MM setting, just to check it. It sounds very close to awesome, but I am affraid to damage my cartridge, and I have no idea how this could happen...
In MC mode, it is getting really loud above the 1/4th of the max volume. In MM mode, I am getting way enough volume 5% below 1/2 of the max.
What can it be the problem? I would prefer to use the phono in the correct setting....

Thank you all!

Sounds to me in the mc setting of the ph10 you need to reduce the gain.
4 settings if I remember correctly.
_3,0,+3,+6.

Even with my 0.24mv cart I only need gain set to 0.
I remember trying +3 and I got a fair amount of distortion so clearly saturating.
Also while in mc mode do not be afraid to adjust the loading as well.
I started at 100 but ended up preferring 1000 as my final setting.
Just use your ears, the ph10 is a very fine phono stage imho.
Also wonderful that you can make all these changes from the front panel on the fly rather than opening up and moving jumpers or dip switches.
Have fun
